I think you are right - I talked to a friend who did cut a big curved wing from a chunk of foam. He used aluminum U channel from Home Depot to make a big bow. He had to raise the voltage to get that much wire to light up, and it took two people to cut it, one at each end. They would each move the wire to a specific spot on the cut line and wait for the other guy to catch up, so that the cut would go evenly. It was not easy.

I asked him if he used steel wire or nichrome, and he said he used the steel fishing line. For power, he used a Variac, kinda like your light dimmer, and an isoation transformer so he would not kill himself.
Normally, he runs it at about 30 volts for his shorter bow.

For the power source on the first cutter he built, , he just used battery packs from his R/C cars. Just add enough batteris in series until you get the temperature you want.

Status: offline 		Critterhunter, glad you are really getting into this, it's saving me alot of time and money, I did run an experiement upon my 25" bow, put the power leads on each end instead of using the plug. I'm cutting the pink foam, so it has more resistance by nature, I even mounted it to the table and did some bandsaw types of cuts freehand with decent results. As I stated before, I'm going with the pro powersource and bow instead of trying to recreate it in house, it will pay for itself in my time, which is directly converted to money at this time.

I cannot tell you directly how to mount your components, I can say though, foam doesn't require the engineering balsa/ply construction requires, ie. there is no structure to mount within to make it stronger since it will always shere off at where it's connected to, fishers packing tape concept is the only thing I've found to really get these foam based creations to stay in one piece better. Alignment of any of it is all about setting up jigs and mounting platforms so that the better you create the original pieces mounting sections and the better you set up your blocks so that they keep everything aligned and allow you to work quickly, ie. glue and set in place without having to eyeball the alignment the better.

Status: offline 		EO,I'd rather work with the pink foam as it looks so much stronger and smoother. I'd like to know what the weight difference is between the pink (owens corning) foam and this white stuff. Sure, the white is coming out smoother than I expected with a bit of sanding but the pink looks so much better. If the weight factor won't hurt me I'd like to at least build the 540 Sub C version of this plane out of it and perhaps future builds of the stock size once I've used all my present white foam up.

By the way, learned this from the Stryker forums and it's something to consider for this and other foamies. There is VERY light weight balsa and/or foam spackle (container feels empty it's so light) that can be found at most hobby stores or probably at a home improvement store. This stuff is great for filling areas of damage on a foam body. It also can be mixed with water and painted onto foam to fill in all the little pores and pock marks. It sands well, weighs almost nothing, stays fairly flexible, and can make a foam body look like it's been fiberglassed (smooth surface). After I've got one of these foamies in the air I plan to brush the entire body over with this stuff for a smooth surface, then paint it with some H20 (foam safe paint...Walmart or other stores). I'm going for war bird looks on these (P38, German Bombers, etc), and perhaps a desert storm camo job as well like Fisher did.

Khalsans, Yea...I've heard of people using batteries to power hotwires. I don't trust the idea myself because of what can happen should a battery go critical. I've read of people using car batteries as make shift welding machines as well and THAT is also not a very good idea. As for the isolated AC transformer from Radio Shack. Yep, I know it's isolated from AC input side but I still don't like the idea of playing with anything AC...even at lower voltages.

Wanted to post a pic of the fuse for the next plane I'm building, it's all balsa/ply, no plans, no specs, just building from scratch freehand with the tiger 400 next to it and to take some raw measurments from. My version is alot stronger, lighter and much more correct in it's dimensions then the original big time. I'm finding it's alot faster to work in this manner then foam, so am bowing out of foam land for a short while.

Status: offline 		Yes, this balsa spackle (also called other things...try a hobby store or home improvement store...the container will feel empty it's so light) will work on any foam so far as I know. It's great for repairing crash damage to get the lines back to the original contours, or to smooth out the surface.

EO, nice looking start there. I've got some big ideas for foam myself. Several ideas kicking around in my head at the moment. Still, I want to cut my teeth on this foamie first and then it's upscaled version before trying other things. I found a thread in this forum (think it was called "Hot Wire Tutoral?" or something) and you should see the foam bodies this one guy has made out of the white foam. They look almost injection molded by simply using wood jigs like we are.

Picked up a few odds and ends from the hobby store yesterday. Hoping to start assembly of the foamie tonight.

Well done! The only thing I saw with your airfoil profile is that the leading edge ends quite sharply. I cut out the templates to allow for the hot wire to follow around the leading edge and leave a rounded nose to it. I am not sure if you will see any performance differences. I would suggest sanding the leading edge a bit to round it off some.

I centered the fuselage on the wing and squared it up with the leading edge. Hot glued it into place. Then I attached the booms and then the horizontal stabilizer. Basically built it using the wing as the base and worked from front to back. I simply surface mounted the vertical stabilizers. They hot glued on nicely. But I used the EPS foam cut in a symmetrical airfoil which gives more support. I followed Foam Flyers recommendations as closely as possible since I have zero experience of my own to work from.

I mounted the servos into the booms right where they attached to the wing. I hollowed out a cavity and hot glued them in place. I think Foam Flyer surface mounted them to the bottom of the wing. I had to make a silly looking !QUOT!S!QUOT! bend in the control rod for the aileron since the servo was not in line with the control horn on the aileron. It worked fine.

As for the fairing on the leading edge of the wing. I went ahead and attached it for the reasons you listed, Added strength and smoother airflow. I do not think that it is absolutely necessary but it made me feel better to use it.

One modification I did make was to cut the trailing edge of the fuselage off even with the trailing edge of the wing since I flush mounted the BP-21. This puts the point of thrust closer to the COG.

As for painting and smoothing. I found that you have to cover most of the tail booms with the extreme packing tape to stiffen them up. If you really want to put on an eye catching paint job you will probably have to insert carbon fiber rods in the tail booms to avoid having to tape the whole plane up. I covered the fuselage and booms with packing tape to keep it good and stiff. The H2O spray paint sticks OK to the strapping tape. You will just have to experiment.

Looking good!

Once again I have to bow to EO for his true plane building skills. One day I might figure out what I am doing. My son and I go the Floating Arm Trebuget to work last night. Flinging tennis balls everywhere.

Status: offline 		Thanks for the compliments guys, I'm going to jig it all up on the next one for true production. I consider both of you guys accompolished builders none the less, it takes true initiative to not only innovate the bow, but to follow through with completed planes, I do have to restate however, if you decide you want to build these for a little extra cash, I'm game to help sell them for you, not sure how your 9-5's are going, but wouldn't it be fun to just build planes out of your house/garage for a living rather then the commute.

When I get around to the original free foam flyer, I'll be using the white foam for the wings, pink/blue for the fuse and booms and balsa for the control surfaces. Also someone gave me a piece of advice upon covering foam based creations with silk and a little wood glue, I think that would make a very strong structure. But then again, I should probably make one out of balsa since in the end, wood is my preferred material of choice to work with and it would be nice to show another version based upon the original plans.

Have a couple of photo's, won't take up space on this server and detract from the original, free foam flyer.

It's amazing how easy it is to get this far, I'm engineering this in ARF format, so it's a little more engineering, but is worth it since it will be really easy for final assembly once it's covered. Day 3, I'll have the wings complete, so it's all covering and hooking up the hardware, will do at my leisure since I gotta get moving on production for the carts, just had a brief window was forced to hold back upon entirely based upon what scale I need to be building along that line currently.

Status: offline 		Ok gents I been sitting here reading from 1 to 10. Heres a few things I learned when I made my bow. If you use gator clips to hook up the power you can adjust the heat somewhat by moving clips on hot wire. I built my power supply from plans off threads in 2004
Not able to install pics. yet but soon. The battery charger is ok IF you wire in the dimmer . You have to be able to control . Im using nicrome wire but want to try stainless aircraft safety wire. Monocoat will work on foam fine just watch heat To hot will bubble foam. I built a duraplane 40 and they have a molded wing that you put extensions on and I used Gorilla glue. It is so easy to use aply glue to one side and spray water on the other BUT you have to clamp or hold together I have a Firebird that the wing has been put back together 5 times. Its a treehunter. I made molds for top and bottom from 1X6 and use waxed paper between wing and mold clamp with clamps and cure overnight. Back to bow. I used 1X2" oak in a H 4ft. Spring and turnbuckle on top. The center bar has T braces
to hold it together and will pivot . T braces Yeah Those T shaped steel peices used to hold stuff together. I wish I could send a picture cause woodman would like. I dont know about Green RC but I have bought servos from other vendors and you cant beat there prices.
Servos lots stronger for 1/4 the price. And they get here from china in two days . Now I have pecked this out I got to figure how to send. Yes I like the smell of nitro. You cant get the fuel buzz on electric. GOOD DAY

Status: offline 		He he, should I change my screen name to wood man, I still like foam, it has it's aps for me, just grew tired it and delved back into my roots material wise, not knocking it. Yes, their servo's are nice, well, as long as you get the right batch, I had some that had no working arms, the last batch were all good, the esc's most worked well, others fried and/or worked only intermittently, so you are taking your chances for that cheap price. Please do not get me back started with these guys again, I have 3 of their ARF's still in my shop I'll be Tiger 400ed with big time and leave it at that, hehe. Their batterys are good, just be prepared for making your own connectors, I wanted a few hundred from him in one of the versions but only could deliver 50 and I'd have to wire all of my own connectors which makes it useless for resale on a regular commercial basis.

The T connectors for getting the bow to play ball will come back to haunt you, I'd put more faith into some elmers between the joints, I wish they would take those things off of the market, I've seen too many people not familiar with hardware using those, there is a reason you never see them used in any commercial, or mass produced product, they just loosen up too quickly. L brackets would be the next option at that point.

I used 2 on each end bolted solid on the upright and loose on the crossbar. Works great I would like to try one of those planes you guys are building but I think it would have to be bigger. SIZE MATTERS I would like to start building some foam planes to sell but what is the question. A few tips Arrow shafts work great but I been thinking about cheap short fishing poles to stiffen wings kiddy poles (couple of bucks) might work. And if I get the CNC cutter made I could pop out wings fast and smooth. K

Status: offline 		If you are bolting it together, then it's a washer, I've seen and dealt with too many that are just screwed in place, they are designed for that purpose, so I retract the reference to that one since obviously you are using it in another way. Bigger, hehe, how big do you want it, I can build something literally scale, it's just going to cost a few extra bucks, hehe.

Along the CNC, you are dead on, it's all about tools and equipment, the better you have, the more you can produce, I replace these off the shelf power tools on an annual basis and I'm just one guy using them, I have my eye on a 25k cnc machine that will cut 1/4" steel and all things smaller to absolute precision but I gotta buy this guys neon sign outfit/equipment and supplies for an additional 7500 and he wants at least 10k to put down in order to do payments or cash out immediately. It's an expensive step I'm not even close to being able to supply unless I drag in some investor, but hell yeah, if you can do it, get it, I'll keep you busy, the proposal was, build a plane, make it presentable, comparable to what others already buy and I'll help you sell it. I very much do think the hobbiest can build not only for themselves, they can make a little change making extra's in low volume, so don't worry about not having god's gift to equipment, it's the end product that really counts.

Status: offline 		Fisher and the rest, thanks for the input again. I'll look into the potential problem you see with the leading edge of the airfoil. Remember, I used the wrong base line for mine and thus the jig doesn't have the slight undercurving....but will check it out to see if I think it's going to be a problem.

EO, when I crank out a few more of these bodies I'll send you one if you still want it. My problem is, as I'm sure you guys have noticed, I tend to get a bit lost in the details. However, this is my nature and I prefer to progress VERY slow and soak up every little tidbit of information before advancing. It's just the way I learn (think they call it micro-management...Or, obsessive compulsive disorder ). However, once I've gone through the process once or twice then I figure out new ways to do it faster, better, etc.

I'm planning on throwing this first body together ASAP...Tonight, tomorrow...whenever I get the time. After I've seen it fly a few times and know what problems to correct I'll make the adjustments and start cranking out a few more bodies. Within a week or sooner. One of those has your name on it EO. I've also got a few friends who are anxious to get a body or two. After that I'm off to building the upscaled version. Beyond that my next foamie might be a copy of Foam Flyer's Skitofrania (or whatever that one plane is called that has one boom and two fins at the tail we talked about weeks back). Maybe my next will be a cub or cesna. I've seen some killer looking bodies of these made from foam. That's a ways off and I'm sure I'll find another hidden gem in the dark corners of the net that I'll want to build before then.

More photos as progress is made...

Status: offline 		Took the unassembled body over to a friend's where we fly to show it to him. He's been asking for a body or two to play with and I decided to give him the parts for a build. So, have to crank out another one for myself. Maybe tonight.

He has two plane guts that he wants to try in these foamies. One is a sky zap, which only used two pusher motors for thrust, turning, lift. I told him he might have to trim the body and/or wing down a bit as the sky zap is a slightly smaller plane stock than your typical 400 pusher (Challenger, this foamie, etc). I told him to use a stiff elevator at the rear that he can flex and adjust for the right amount of lift at full throttle. Might work, might not. Worth a try.

He also has some stock Stryker guts that he'd like to try in it. Since my experience has only been with V-Tails and the Stryker's setup, I have no experience with planes that use an aileron/elevator configuration. So, my question is this...Can you use two aileron's on this foamies wing and the Stryker guts to turn/lift, etc? I would figure it would work as the left/right will result in one aileron moving up and one down (for even more agile turning). And the up/down movement of both flaps for climbing and descending should take the place of the elevator in the back. It seems simple enough to me but figured I'd run it by you guys in case I'm missing something here? I'd also figure you could do this with Challenger guts since V-Tail and the delta configuration of the Stryker are the same, just reversed in turning configuration?

Status: offline 		This is a rough one to wake up to. Whats the big idea trying to make someone think this early. I have a Firebird Commander and its only 2 channel so theres no way to get away from the V tail and have mush control BUT if you have one of those models with 3 chan.
ailerons and elevator would fly like a champ. Rudder is not used by only the best pilots . I know I sure don't use mine . Only on the ground to stear. The pres. of the flying club im looking at told me if you can fly a V tail you could fly most anything. But one of the 3 chan. units would give you guts to have a flying fool . The aileron only might work as well as the V tail but I think your asking for a spin. But thats MY thoughts and thats what this is all about. Im gathering more parts for the CNC cutter im working on. I can't wait to push a button on the computer and cut out a perfect wing with holes inside to make it lighter. Think about it Critter. A wing 1/3 less weight than what your using now. And I figure just as strong cause the hot wire leaves a coating on the wing so on inside it SHOULD make it stronger. Don't you think ? Imthinking about you guys plane to build but I would have to have at least 4 channels. The 3.7 gram servos X4 and a 6 channel receiver 42+ grams for radio + bat.= how big of motor? And how much wing ? FOUR servos ?? Yes I don't have to but a slow landing is Sooooo much easyer to make. Got to have a servo for each aileron. Breakfast is ready lets go eat.
Thats one thing im great at. And the wind isn't blowing so maybe the grands can go to the park and I can FLY!!!

Status: offline 		Critterhunter,

I am not so optimistic about putting a v-tail mix system in this plane and getting it to work. If you are using the RX from the F-27B with option for v-tail or ailerons/elevator I would pull the jumper and set it to aileron/elevator like it is on the P-51 and ME 109 and not try v-tail. As the name (V-tail) implies you are assumed to be controlling the plane from the very tail end. (Even with the Stryker). By trying to put the v-tail mix into use at mid ship you will probably do fine rolling on the long axis but trying to loop or even bank and turn may give you fits since you will be trying to overcome the horizontal stabilizer the whole time with little leverage since the control surfaces will be so close to the CG. I would stay away from the V-tail mix. But I am a nervous guy anyway. Heck try it. The only thing bad that might happen it that it crashes. And we all know that has never happened to anyone before.

And I don't know much about the P-51 or other planes. I just know my firebird is junk but I still try to fly it. There ought to be a law against 2 channel planes. So much for me badmouthing MY electric. I dug out some wings that I cut when I first started playing with hot wire. I have some foam that comes on the end of the dish receivers that can be used as a body for a boxcar. The 2 peices go together with a large void inside. Yes I called you guys plane a box car BUT its a nobel plane.
P38 ?? NAH! Maybe with lots of imagination. NOW crittercatcher is mad at me. At least its not a flying lawnmower or doghouse. Now those guys have some good drugs. Yep im going to get some foam and heat the bow. Critterhunter I wasn't making fun I was Having fun. But I do think if a person had one of those planes that has rudder and elevator I would go to ailerons instead of rudder and you'd
have a plane that could most anything. Now im going to look for a cheap 3 channel to gut. SEE YA

It's wingspan and control surfaces need revisions big time, that and the carbon fiber tube fuse broke very early on and it never flew well afterwards, you gotta place the battery pack further into the cabin, not in it's intended battery bay to get it to fly better, I figured that one out right off the bat.

Along the aerlons, I was thinking exactly as you critterhunter, looking at the full scale aircraft, where they were able to control them independantly ie. both flaps being able to go up and down at the same time and then being able to alternate for turning and banking, unfortunately that's not how most RC style planes work, but I can say, it is possible to do with a 2 channel radio regardless.

Splice both aerlon servo's "Y cable" together, place one servo backwards so that when you activate them, they will turn opposite of each other, you then have another channel for your elevator, don't worry about the rudder, I never use it and looking back at my ARf's, didn't need to buy the extra servo and hook up the hardware to it in the first place. You may have to get used to the controls working in a different manner and it may only be able to turn one direction, but at least that's one way of doing it. The other would be literally to take the controls from the v tail and connect them directly to the aerlons, making sure the plane naturally climbs when you give it juice, similar to most 2 channel planes, would make a nice transition to 4 channel. Except for the fact that the plane turns faster in 4 channel mode, it's not a huge difference between that and 3 channel, in fact, I'm finding the tail control only system a bit harder since you don't have the direct control to correct a mistake, ie. you gotta wait for it to get around to it, so it's like driving a bus in the indi 500, slow to react, and the direction it's facing is pretty much the direction it's going to go towards and when it gets around to changing, it may be too late.

Attached are the latest updates on the current work in progress:

before I got to finish it my time ran out and It went to waste . Oh well the dog has to have her turn. I have a question . I been looking
at the picture and wonder if the balance is 30 percent back from leading edge . And your rite about the firebird being nose heavy but I had good luck using the wing shim to level the flight. But the plane is still junk But until I get something built its what I have in the electric line. Its 12 miles to the RC field and theres a vacant lot 3 blocks away . And me not driving thats a biggie. Later====K

Status: offline 		There were more then 4 beers total into that entire project, hehe. I've kept very close to the original ARF spec wise so I didn't have to worry about balance, 30 percent is close, I'm still adding onto it, so can't say exactly where it's at, but should be very close to the original and I can of course add weight where-ever necessary. I'm not doing ARF's any more, going to sell what I have and replace them with all of my own creations. Everybody kept telling me it's impossible, but I'm finding it not only easy, I can make things user friendly and of course, reinforce what needs it the most in the key areas of the current Tiger since it has crashed a few times showing me what needs addressing.

Status: offline 		Yep when you grow up to be a big boy you will learn that foam is stronger and most of all faster and you will find you will have to drink lots less to build up your airforce. But who am I to say. At least you get to fly. Its been months since I put my plane in a tree. But thats what you get when theres so many trees around. If I had a better plane I could fly over the nebours? houses but the firebird don't have much control. That does it! Tomorrow im going to start on something new. OK you guys have built the So.X I have 4 battery packs for my firebird 2 stock 7.2 & 2 8.4 What motor can I use that will work with my batterys Would the firebird motor work? HEY im a nubee on electric . My daddy taught me to be afraid of electric. ANYTHING THAT YOU CAN'T SEE AND WILL KILL YOU YOU GOT TO RESPECT. I guess I need to do some hunting . Ken

Status: offline 		1st off an foremost, the absolute most time my "Daddy" spent with me was to take me and my broither up to his latest camping gig, fishing was an option, he never really participated, us kids were as always just along for the ride. I tie my own flies, he never fly fished, airplanes and hobby anything, not even close to his realm, I envy you having an actual dad, not some idiot that told his son he was more expense then worth it................

Do NOT mess with Topher and Critterhunter, you will be messing with me at this point......... I stand behind my friends and you do NOT want to step toe to toe with me, you will lose more then you can possibly imagine.

Other then that, consider what I say, I'm not flaky, and you very much will benifet from me being your friend, I honestly respectd your point of view and can utterly mirror your frustration with this entire ARF/Rc world, it's just wrong, and for the record I am the only Yank that's doing something about it, especially when integrity is at stake, let you decide what it means, and what I do and say and us working together or against..............

Status: offline 		I'm late for work and just woke up myself so I don't have much time or a clear enough head to respond to all at the moment. However, thanks for the advice. Fisher, good idea on the 27B jumper. Not sure which RX he has so I'll have to take a look. In fact, another friend brought over his new 27B RX last night as I was helping him put together a stock Stryker. I gave him four or five junk bodies, motors, and numerous other stock Stryker parts to build his first one. Told him not to go new with parts until he learns how to fly this abused stuff I had laying around. Anyway, the RX I gave him was fine until he tried to force the servo plugs in and out by hand and broke the solder on the pins. Anybody who's flown a stock Stryker knows you need to use plyers to hold the board's plug ends while you insert or remove the servo plugs on the RX, otherwise the pins will bust loose. So, he ended up getting a new 27B RX for it last night to bring over. About seven beers into the project of putting the bird together I realized the servos where not respond in the correct fashion. No instructions with the RX so I had to guess what needed moved or removed to set it for Delta wing mode. I'm going to find and print the instructions out to be sure but I think I figured it out. The two pin jumper probably is for nimh/lipo. With it in it should be nimh. The four pin jumper needs to be completely removed. Anyway, it appears to be working. Now, if my other friend has the 27B RX it'll be easy to set it for aileron/elevator. If not then I guess he'll be trying the two aileron configuration with a fixed elevator. Worth a try anyway.

Status: offline 		Critterhunter,

Sounds like you have things figured out. If he only has delta (v-tail) capability I will be most interested in hearing how it works out.


EO,

You have probably already seen this but the attached link is to another foam plane thread. It looks a lot like your current project using different materials. The construction is crude compared with your product but still very nice results from an appearance standpoint.
