Kerwin, sorry for the abrupt landing,, but hey It happens,, and It happens to all of us LOL, glad you got some flying time in.

T_ _ _ Ted glad to hear you received your parts, never tried the drill and tap for pressure so I don't know that answer I've never used a pump and never have had a problem either, so let me know what worked best.

rccar keep saving lol,,, I'm doing the same for my twin 61's

well wing number 2 has been sheeted and 3 will be done today,, now all thats left is mono-coting I will send a pic of the finished Twipe as soon as all the wings are wrapped... I think that may be a few weeks though unless I hit tonights lotto,,, I think I'm going to need 3-6 rolls Now I get to start working on my new mustang

Waldo, I like the T_ _ PE (lol). Make sure you don't forget about us after she maidens.

I decided to go with the CC BEC and thunder power 1320 for my receiver battery. It's considerably lighter than a 6v nimh pack which is nice. I will have to have an easy way to remove it for charging but I don't think it'll be too bad. I'm waiting on aileron extensions before I start really digging in but I'm really just entirely too excited about flying this thing.

One side question... With the Saito 82 and probably a 14x4w or 15x4w prop, is a metal spinner going to be absolutely necessary or will a plastic one work well enough? I'll spring for the metal if necessary but I'd like to keep the weight down if possible. I'm not even opposed to just using a little corsair-style nub like I have on my OS 70 on my Ultra Stick 40.
-Eric

Ok so I decided to drill and tap with the help of a little jb weld also. I will put it on tommorow and fire the beast up I will post pics tommorow.

I have always used the self tapping fittings that way all I have to do is drill an screw the fitting in I have used the perry pump on an old tigre 2000 worked great for a consistant needle setting.
why do you want to run a pump.
Waldo can you post a few pic's of the stang as she goes toghter I am sure that i am not the only 1 that would like to see her go together
Well I took another try at flying with ski's today it was 46 an sunny and with all that snow it was bright an really felt quite warm but the snow was really soft and on landing the plane only went about 10 feet until it sank 3 inches into the snow tore the gear up but other than that it was a great flight now only if I can get the T---T up. I may go looking for a road in a construction site some where and see about flying off it I just hate those nasty curbs is all

kerwin50,
Are you using skiis that are too small for the weight of the plane and snow-type? Are the skiis fixed rigidly to the landing gear or can they articulate? Have you taxied around at higher speeds to see how they ride and if they are indeed sufficient in design to ride out of the tracks they create? Here, in Northern Michigan we have powder that is so air-entrained (puffy) that the snow comes in contact with the bottom of the wing when the plane is set down in it. It turns out that skiis that are rigidly fixed to the gearare easier to fly, but it's neccessary that they be parallel with the fuse. CG also has to be considered with the skiis on. The two major considerations have been the area of the skiis that come in contact with snow and making sure the front of the ski is curved up enough so as to ride up and out of the tracks they create. Just a few thoughts for you to consider.

DT thanks I think that the ski's are two smoll for the astro hog. They are not fixed rigid.
There was a real stiff coating of ice on the snow the day we taxied her around but now that the weather is warmer IT won't. when I flew her I would open the throttle up full while a friend of mine held the plane once max r's were reached he then gave it a little push and in less than 20 ft she was airborn.
Here a couple of pics of my air strip. The 1st pic was taken about 20 ft off the runway looking south and the 2nd pic was taken about 20 fr off the runway looking north. It's not the greatest airstrip in the world I had my eye on some other pieces of property that would of made a better field but the wife was sold on this piece of prop so that is mainly why I bought the T---T, so that when I wake up in the morning an have a cup of coffee go for a couple of flights before starting my day.
I have been flying the sig se there for the past 3 yrs but I am very bored with that plane.

kerwin50,
It looks like you have a beautiful spread there! I've been trying to get my wife to move from town to a small farm and some acerage of her choosing, but alas I remain a town-dweller! Fortunately, living here in the sticks means I just have to drive a 1/2 mile in any direction and I'm in the bush. (Plenty of places to fly in the winter, with only three in the summer.)
The T_ _ _ T is the perfect plane for what you've got going on............keep on flying!

Downtrodden

Well it's cold this morning wind chill -5. when will it ever warm up. They say it's going to be 55 sat so I am hoping to maiden the T---T sat.
I am really hoping that old saying is not true for march in like a lamb out like a lion

Kerwin that looks like an excellent flying zone for sure, I remember trying to fly up my neighborhood street, avoiding houses on both sides along with telephone lines, trees and power poles, it was never a grand situation, we took off the wings so it wouldn't lift off and then mostly I just raced the neighbors up the street when they would drive by, but that always ended up with something broken on the plane, but at least I got to use my glues that night.. now the wife is wanting to move again so I am about to lose my acres of corn fields all around my house, hopefully I will be able to find something with the same amount of openness around me, or at least closer then 40 minutes to my club site,, Oh the packing and packing and packing[&o] We just did this 2 years ago... lol,,

I'm pretty sure I'm going to do a Mustang build thread I will post the link here when it is complete or as I'm going.

T_ _ _ Tedskies - How'd the ol drill and Tap go?? Where's those Pics??

Rccar, not to worry I think I would be shot if I didn't post the Video of the maiden Twipe after all the talk and Pics posted.

DownT,, Getting any flying in? I'm not hearing many stories of flights. You guys are what keeps me in a bit of the shakes usually, everyone talking about their flights all winter whilst I look out my frozen glass windows with enough snow to make things miserable but not enough for ski's, this winter has been weird,, we can get 8 inches 1 day and you can see ground the next, we have had about 3 or 4 storms that started as snow and ended as rain, just to make everything bumpy as hell and icy,, the same goes for tonight, were expected to get 10" but ending with rain, I hate that,, either SNOW or RAIN, the mixed stuff is terrible,,[:'(] and the same is going for this Friday also,, I can't wait until April. [:-]

Ok boys here we are gettin another snow storm today but only 3 to 6 inches are expected today but more on Friday. Waldo drill and tap went ok just secured it with some JB weld to be sure that is not going anywhere. Here are some pics of all my projects on the table right now. I just got the turtle deck on my laser done and the covering is started as you will see. I did get the fuel tank put in the cap and fired it up last night with her new muffler aboard. I will tell you that this thing is a screamer. I am running a 20 inch prop its getting about 35 pounds of pull and about 9500 rpm. I am thinking a bigger prop will be just fine lol.

Ok so here is another pic after just a little more covering. I am so excited for this weekend it looks like we are going to be warmer so maybe I will get out and fly this time. Well I am working hard on all my birds I am going to have 4 birds to maiden this season, that should be a great day at the field for me. I am finishing up the big cap today also just have some carbon to put on the pushrods and she is done and ready to go flying.

Hey Eric, I dont think your question got answered so Ill give it a shot!

There is nothing that says a motor even has to have a spinner, much less an expensive spun aluminum one. If you want to run plastic, it will work just fine. Aluminum obviously holds up to the starter motor better. Most decent (re:not worn out) four strokes dont even need that. When properly tuned, a gentle back flip will have them running. Some guys just grab the spinner to do this. Also, you should be able to just lay your fingertip on the airfoil of the blade to back flip, dont hook it on the edge of the blade for obvious reasons. This way when the motor "catches" and spins forward, the tip of your finger just slides off the airfoil and you are not having to "time" your release of the blade. A (handicapped) buddy has a Surpass 70 on his UCanDO and when I start it for him, I litterally "throw" the prop backwards from the 12 oclock position and it fires like a dream. This "throw" means my finger has traveled about 1 inch within the prop disc and is long since clear of the prop disc when the prop bounces off 3 oclock and comes back.

All that being said......I run aluminum on everything

I bench ran a Saito 80 the other day that I got for a GP Ultimate. Ran a 15x4w and it pulled like a freight train, so if you have the clearance you may want to go even bigger with the newer 82. Ill bet dollars to donuts that 82 will float the valves with a 14x4w....I could be wrong, but you dont want that motor screaming in the RPM range that it will probably spin that prop.

Hope this helps...Shane

While were counting...I should have 6 to maiden here before long. They dont seem to go very fast till you realize that in a few weeks you will have MANY new planes Kudos to all!!!! Pics, planes, etc...everyone is gettin excited to get in the skies!

Hey there, sportsfans. . . .I haven't chimed in for a while, but have been happily flying the wings of both my TwT's, and when I saw the spinner post, I had to also make a $.02 contribution to the fund. . . .

On my Saito 72, I'd ordered a custom TruTurn spinner to fit the prop choice (14x4), since local HS didnt have anything in stock that would fit. I also had to purchase a larger adapter cup for the starter to fit properly. . . . a lot of added expense that was really asteticaly pleasing, but added no improved performance.
The second weekend I took the plane out to fly, it seems the the higher compression of a realitively new engine took it's toll on the spinner.
Quite by accident, I bent the spinner. Another flyer had in his box a OEM type spinner nut. It was installed and I returned to the smaller starter cup. to my surprise, the engine was much easier to start as the fit was more secure between the peices. thats the way I'm going to leave it at this point. . .
so there's my experience with it. Your local HS will mostlikely have one as well, and with the realitively cheap price, you just might want to give it a try. . . .

I need some help......my club is 10 miles away....not a big deal. But because of having two small children, I can't always make it out there. I have 2 large open fields across from my house, on the other side of the fields is a major 4 lane highway. I could fly my T***T and other nitro planes in these fields, but I refuse to because of insurance, the highway and the unexpected. However I think an electric 3-d profile would be fine for these fields. The profile would be flown in closer to me .....I would be 1/8 mile from highway (speed limit is 35 in this area), but not an AMA field so the insurance thing comes up....

Any thoughts on

1. Flying this close to highway traffic?
2. Flying without AMA behind me (insurance)?.....and yes I have homeowners insurance
3. A good choice for an electric 3-d profile? Yes I love my T***T, but there are times that I can't get to the field to fly it. Stepping out the front door to fly would be a great option.

My new flying site is Right next to a road and pretty close to the freeway and some high tension power lines and a Gun range. but i'm going to fly all my planes there anyway.

AMA Insurance not so sure about. But what's the point of having AMA Membership if there not going to back you up in this hobby. Guess i'll find out just how good it is if i hit Something. i'm sure the guys at the gun range will shoot me out of the air if my plane starts heading towards them.[X(]

But theres alot of open ground to fly over and theres Some jet pilots that fly there and i dont go that fast. Don't know much about EP 3D powered planes don't own any Parkzone spitfire is my EP plane and it did well yesterday flying next to the road and there was quite a bit of traffic. Main problem is people Slowing down to watch. Wouldn't be so bad if they would just pull off the road and stop to watch. But they drive along and rubber neck and drive off the road. but thats not my problem if there just dumb.

Of course Some fool will come up with hitting a power pole and it was my fault cause he was watching me fly my plane and was distracted while driving down the road. The Jet flyers don't have that problem there planes move so fast no one can see them driving down the road i guess. But i'm ready to maiden my TwisT. Was going to today but the Wheather turned on me Hopefully Tommarrow.

I'm just happy to have a place to fly again and Some fellow flyer's to join in on the fun.

back several years ago I use to fly off a field next to a trailer park and a buddy of mine ended up putting a plane right thru the roof of this moble home. The AMA had no problem paying the home owner, as a matter of fact he ended up buying a plane with some of the insurance money and we taught him to fly.
Waldo I feel your pain, is there any way we can have 1 or the other. Right now I have about an inch plus of ice on my driveway which btw is 400 ft long and we are iced in unless I put chains on.
They are saying it will be in the 50's sat so I am hoping to fly, still wanting to maiden the T---T
I have had the chance to run some more fuel through the os 61 an boy is she smooth, I am so glad that you guys talked me into getting the os 61 after flying the astro hog with the super tigre 61 THANKS GUYS

Dad_Roman, thanks for the reply. I don't even have a spinner on the OS 70, but I know a metal one was pretty much necessary on the bigger Saito 1.80. I'd like to keep this thing as light as possible without going crazy, but I really do like the looks of the aluminum spinners as well as the durability. The cost doesn't bug me too much since I only buy a new plane like once every other year it seems like any more. For that reason, when I do get a new plane, I try to do it right. I seem to learn a lot each time and I think I may have finally gotten it almost right on this Twist. My Ultra Stick could really use better servos and I'm pretty sure that OS 70 with the pump is actually defective. It doesn't pump enough fuel sometimes and I think it's worn out the ring, sleeve, piston, whatever wears out in there. My second four-stroke, that 1.80 runs absolutely wonderful. I did a good job with that plane, but wish I had done a few things a little differently such as the fueling system (my first cowled plane), and the receiver battery. The twist will have the more solid engine (potentially), awesome strong servos, and a LiPo/Regulator for receiver power.
I guess I kinda ranted a little bit, but I'm hoping I don't end up with anything on this plane where I say "man I wish I had done that differently."
-Eric

Man, pretty much anything from E-Flite is good to go. I haven't had much experience with flat foamies but I'm around them all the time. I had an electrifly FlatOuts - Redbull edge 540. I built it straight out of the box and had no problems. Of course, I got their recommended brushless upgrade, and the thing hovered at half throttle and would climb vertical at still less than 3/4. It was hilarious.
I'd like to get another flat foamie because it was so much fun to fly, but I now have to drive in order to fly electrics, so I might as well make 2 trips to the truck instead of 1 and bust out the ultra stick or Super Star and go for it.

Edit: There's a guy really close to where I live... he comes in for CA glue and minor stuff sometimes... Name is Mike, and he uses a CNC machine to cut out flat foam planes. The company is called Fancy Foam and I've heard a lot of good things. I wish my boss would let us carry the stuff but Horizon pushes so much new E-Flite stuff on us that we don't have room for anything else. Granted, the E-Flites are awesome planes but it's nice to have something different for once...
-Eric

That 70 surpass would half to have some serious use to wear out the piston an sleeve, I've got a 91 that is 17 yrs old doesn't have alot of compression but boy it sure runs well.
Is there alot of play in the crankshaft if not you are more than likely having a fuel problem.
I've seen spray bars go bad from adjusting the low speed needle in to far an it ends up hitting the high speed needle. Your reg could also be bad. you can send it into hobby services and at least get an estimate. or just replace the carb with a non pumped carb

The thing actually runs really well... it just doesn't have much compression. You can hear/feel it blowing by like crazy when you turn it over by hand. Also, it really doesn't have much trouble getting fuel any more. One day when I went to fly it, it wouldn't start... this was after I had the klunk line fall off inside my tank. For some reason, after that happened, I had to *richen* the mixture screw (not low speed needle on this engine) probably 1/8 to 1/4 of a turn and it was back in business. The high speed needle didn't require adjusting, just the mixture screw.
I guess it's possible that I turned it while trying to figure out what happened to the thing when I didn't know for sure that it was the klunk line, but I don't think I messed with it.
Now that I'm actually talking about it and thinking about it again, I haven't really checked the valves in a while. I've never had a valve tighten up and cause a valve to stay open though. They usually just loosen up like they did on my 1.80 Saito.
If I get bored tonight I might check the valves though and let you know.

Edit: What do you mean by play in the crankshaft? Rotational, lateral, longitudinal?
-Eric

Check for carbon build up, especially on the exhaust stem

And do a "leak down" on the seats.

.

What is a "leak down" exactly? lol
I'm still kind of a n00b to 4 strokes I guess.
-Eric

Leak down Refers to how much it leakes past the valves when there closed the seats are what the valve faces mate with to seal the combustion chamber on the compression stroke.

Well maidened my TVV!$T today with the O.S. 61 FX and macs tuned pipe flew for almost 20 minutes on one tank of fuel i flew it till it ran out of fuel see how long it would fly on a full tank. probably would have flown longer if i wouldn't have been doing Straifing runs with it and high speed fly by's. Wind was blowing from the South east at 15 to 20 mph So dead sticking is not a problem it just floats to the ground. CG is a 4 3/4 inches but has to be moved back kep't nose diving had to trim up elevator quite a bit to get a level flight at half throttle.

Plane Screams with this engine and is loud as H**. Plane must do at least 80 mph in level flight. Unlimited verticle at 1/4 throttle. Full throttle is just insane it sounds like a bomb falling out of a bomber gives that high pitch whining sound.

Scared the People at the gun range lol. Thought they were under attack. Whole gun club was there. One guy came over Ask me if i was intresed in Some rc equipment engines ect. And to not bomb them.[sm=regular_smile.gif]
Would have taken him up on his offer, if he was giving the stuff away. But he's selling it for some pretty high prices and I have a Ton of RC equipment myself that i need to sell i'm running out of room.

But the new flight field is awesome nice and open and flat. with the bigger engine the rolls are a little slower and rudder and up elevator puts the plane into a scary dive instead of the Flat spin i was trying for. So Going to have to operate and build that hatch behind the cockpit and move that battery to get that CG back some. Last landing was a bit hard and i heard a crack and was thinking OH NO[:@]. So i will have to do an inspection on it. Make sure it isnt damged to badly was a small crack sound and theres no visable. Still always better to be safe then sorry. It bounced a couple times on the Landing. The dubro plastic landing gear is a good investment for this plane on a rough landing it flexes and absorbs alot of shock.

http://www3.towerhobbies.com/cgi-bin...&I=LXNM65&P=ML

All in all it was a great day for flying and i'm very pleased with the new engine. I'm sure i have the fastest TVV!$T in the Region. Now just have to maiden the 150 thats going to be intresting it weighs 12 Lbs. And has metal landing gear No hard landings with it. Going to have to be a little more carefull then I am with the littel one. I'm sure it will bend the gear or break something.

So Spring is coming and you'll all be out flying Again before to long

Link thats awesome!! you must be lovin it looks like a nice T_ _ _ T factory over at your place, I flew without AMA for about the last 30 years, not that I wanted that way, I guess you could say I was Darn lucky, after flying for so long and seeing what can happen over the years I was a fool not to have it, but I was pretty much just on my own all the time and flew in public places like a college field with all kinds of sports going on around me, then when I met my wife and moved out to the sticks, I felt much better about it, and now I'm with a club, so AMA is a must. I like it that way. we also have some hunters that practice near our field so If I ever heard a gunshot and my plane acts funny, we have a club that would have no problem in seeing how fast they can re-load during an aerial attack[>:] I even offered a $5,000.00 purse to someone who thought they could shoot my T_ _ _ T out of the sky, but the catch was If I hit them they had to pay me, after seeing the big ol prop spinning and the way the T_ _ _ T could snap on a dime, I haven't had a taker yet.. LOL,, I guess telling them that even if they hit my plane it might just end up with a hole in the fabric and it was still going to keep coming right at them, and they didn't feel like being attacked by an R/C saw blade,, I think its a little intimidating.[&o] just for the record all that was said in fun... or was it[:-] good luck on the 150 maiden

I use no spinner at all on my 70 4 stroke it helps to keep the weight towards the back in my case.

T_ _ _ Ted nice job!!! good luck with all the maidens,,and thanks for the Pics

Kerwin I would love to be iced in right now LOL,, it comes in at night, I clean off the van in the morning and its all a Ice mixed snow mess when I get home.... good grief,, can't even snow blow it...

well all the wings are done for the Twipe,, just need to wrap them now.. come' on Spring thaw

"Leak-down" happens after the age of 70.
