Ok. Gotcha.

My point on the Palmer plans is that he is notorious for underestimating the weight of his designs and anyone I have communicated with that used his recommended engine sizes have had to replace them with larger engines. My OV10 Bronco had a target weight of 19 pounds 11.58 ounces and indicated that it would fly on 2 .90 4 strokes. If (and that's a big if) you could build the airplane at 20 pounds then the 90s would have been ok. Mine will weight about 35 pounds and will be powered with a pair of 26cc MVVS gassers. There will be no runway creep at that weight.

The C130 will weigh more than the target weight of 22 pounds so I am just trying to give anyone planning on building one of these big guys that they will need to plan on more power.

Just a thought on aircraft creep.... Wouldn't a simple solution be to add an air braking system in the wheels? THat would be a simple "T-fitting" into the air retract system and a brake cylinder. With a plane that size there would be plenty of room.

Brakes are common on today's jets so yes it can be done easily. You should use a separate air system for safety.

Robart is suppose to be coming out with brakes for there wheels...They been advertising them online (Compact Brakes) for the last 2 months..also in the magazines...called them up awhile back and I asked them when they would be available, and also price....the answer I got was " Gee, don't know when they will be ready, and don't know the price of the units either".......Expected something like that from them...Hell,had to wait 3-1/2 months for my retracts for the KMP B-25....Great service huh, fellow modelers...........bet the brakes won't be ready until next year.....nuff said

Does anyone know which hinges Gunny11 is using for the flaps? I think I've seen something like that from Century? I have a kit with a sheeted foam wing that I want to add flaps to.

I have a c-160 and everyone has asked me if it was a c-130 i have never seen the c-130 until now, it does look something like mine, i bought the arf and it is such a pleasure to fly but the color of creme and white this week i had the leading edge painted red and i hope that it helps me to see when turning towards me is the only time that i cannoit see the wings at all, i have this bad habit of hot landings but there all smooth but not really needed so i have been trying to slow down on touch downs, it flies so nice, i have only had a few of the twinstars and this c-160 that i love dearly so i have just ordered the phoenix my problem is what to use for engines, it will take up to a 60 two stroke, what i want to try on it is two OS-55AX Engines or i could use the os-60fx but i have heard alot of good things about the 55ax engine it is strong and it runs great but the air is thin here but i do not think that little bit will make alot of difference, what would you guys use, rollie

who did you order the phoenex from ?

Hello Frank
I ordered it through the hobby shop, he got it from cedar hobbies and he always gives me a better price plus i dont have to pay for shipping, can you believe it i took my c-160 to the field this afternoon a nice day, and another guy tried out his prime cut for the first time and it went well, i took off and done a few loops a roll and landed but my idle was a little high so i gave her a few clicks down and it run so nice today to i was just going to go around the strip to do another landing, im just a sport pilot but a good pilot, on take off one engine started to quit so i cut the throttle right back but it quit anyways on take off and the right wing dropped and went right into a spin and unable to get it out and down she went, i have not crashed a plane for over five years but this past month i have put this makes the third one down, if i had mg servos i would not have lost the first one the second was my fault, so i go to find a pile of wood and where do i find it, right in the middle of a swamp a small swamp but a really muddy swamp, the plane was upright and from what i could see did not hurt a thing, finally after getting to it one step at a time sinking up to my butt, i got the plane and then getting back to the ground was another story, muckall the way one step at a time i got it out and the wing was a little bit off of course it was soaked, other then a few scratches it didnt hurt a thing, i had to pull the wing off leaving the third bolt there still into the block of wood that holds in on and the servo arm that holds the front tires on broke other then that i took the wing off and draines the fuel and there was no water in the engines so i refueled it and they both started right up and ran great, got to do some patching but it seemed that it could of been so much worst, so what do i do i buy another twin that i am sure that i will love it as much as i love the c-160 it flies so nice and will again, rollie

howdy
sorry to hear about your C160,but some days things just dont go right.
im just about finished my 160,have to wait for the other OS25 LA from the LHS.hope the snow holds off for quite some time yet.

Hello Frank
I have some really good friends, i took the c-160 to him tonight, it was funny to see that plane after watching it spin out of sight and expecting a pile of wood and there it sat of course in the center of the swamp. mud and muk, the worst part of it was getting myself out of the swamp, one step at a time, i took it to my friends home and i did not expect to work on it tonight, it is midnight and i just got home, all the cracks and scrapes are now gone and still some to go but he told me that thursday we will paint it, it is now so smooth and friday i willfly it again, i am going to build the phoenix by myself with my good friend there to give me support and to make sure it is done right, i have built many big sticks but when it comes to an expensive airplane and such a nice looking one i dont want to make mistakes but i also want to learn to build a nice plane buy myself without paying so much to have others do it for me.

gkamysz, the hinges i used for the flaps are from yellow aircraft. The extra large ones and cut them to the shape needed. Here's an under the wing shot where the out-board flap would go.

Did you say that you were going to put 25 size engines onto your c-160 if so i think it will do just fine i guess alot depends on where you also live along with the alt. is most important, you may not have the power to do some of the things that you want to, it takes me full power to do a big nice loop bt i am sure that the 25 will do just fine and will have good power to fly it nicely, rollie

Thanks Gunny! Those were the ones I was thinking of. I saw them at Toledo and should have bought them.

Yeah. I was getting geared up to cut my own out of carbon fiber but getting ready to dread it. But also lucky for me I saw these too at the toledo show and bought them.

I made a composite main spar. It utilizes the phenolic "cardboard" tube in which the aluminum wing tip tubes mounts in "sockets" and vacuumed bagged w/ epoxy resin a carbon braid sleeve. I've also added a balsa plug "a stop" for the al. tube. The entire assembly is glued into the wing sections using the al. tube and cradles and weights to keep things aligned, straight and true. Of coarse ply shim spacers where added between the tip panels so they don't accidentally get glued to the main wing. The glue I used is pro bond polyurethane expandable glue. Also I drilled a small hole through the main spar to wick thin ca to glue the balsa stops in place.
Gunny

O.k. now. This is my sequence of how I attached the wing tip pannels. Basically a dowel plug is glued into the top of the wing, flush w/ the surface and up against the wing tube socket. It is resessed so that the socket head cap screw is flush with the surface of the wing. The al. tube has a hardwood plug glued in it and is tapped for the cap screw. Important! do not drill through to the other side of the al. tube. Also if you are using the original seam for the wing tip parting line, then for even greater strength these should be on the bottom of the wing. But with my short tips, I can lift the 20 lb finished model by the wing tips with no problems of seperating at the bott. of the airfoils seam. Here's my wing tip cannoes. Ha! Ha!

Gunny

Tail attachment details. Very typical construction. Pictures tell the story.

I will be darned, i got home tonight and i got a call from the hobby shop freq. rc and my phoenix has come in we took everything out right at the store and checked everything right there the owner dennis i think was more excited then i was, it looked so good and the cover was on tight only a wrinkle or two, i really loved everything about it and the way the covers go onto the nacelles and the cover to the canopy, it is well built and when my friend and i get done with it, going to put two os-90fx engines onto it and were going to beef it up where ever needed and i am sure that it is going to be one sweet airplane, also going to use alot of my own personal things like fiber rods instead of the metal rods, i really have not looked over what is in the bag to see what is really there but i am going to start on it thursday, got to save for the engines so im in no hurry, also the magnum four stroke 91 goes for only 149,00 each, now that is not a bad price, i have never owned a magnum but my friend does have one and i have seen it run many times, he starts it with his finger every time and it runs so nice but sill he is the only one i have seen at the field anyone else got one out there that runs nice, you know that it is so much fun just doing the little things but i am going to learn so much with my friend helping me to build this plane, he builds alot of kits and does such a great job doing it, just looking at the bare plane give's me shivers that a guy can take a bunch of wood and make something like that and make it so it looks so good, i dont think as many guys build kits like before now that there making the arfs so nice but the guys that build the kits really are the builders that know whats going on, someday maybe i will try and build a small kit myself, something that is easy for a first time kit

I have a 91� span C 130 wing with no instructions.

Does anyone know if the ailerons should have differential throw? Also what is the amount of aileron travel?

Thanks in advance.

Bill

I don't have differential on my ailerons, but do use rudder coupling for smooth turns-maybe about 10%. As far as throw, been too long since I checked it but it doesn't take much throw. Mine is the QF kit, 102", 17# dry.

HOBBY PEOPLE NOW HAS THE 4X.25'S C-130 HERC COAST GUARD ARF LISTED. NO PICS POSTED YET . PRICE 449.99 . I THINK IT IS THE 100 INCHER!!! IN THE GEAR SECTION THEY SAY SCALE RETRACTS WILL BE AVAILABLE,,,,WOW!!!

What is included with the Quality Fiberglass kit? Any help would be appreciated. Thanks.

QF kit includes: Fiberglass fuse and vertical stab, shipped in two pieces.
Fiberglass nacelles/cowlings

Well, I somehow screwed up and posted before I was done. anyway, fiberglass fuse and stab, fiberglass nacelles/cowlings, foam horiz. stab cores, foam wing cores. One sheet written instructions, one or two (don't remember which) app. 24 x 24" plan. You supply the rest. go back to page one and you can see the fuse pretty much as you get it. It is joined aft of the wing saddle. I liked this feature. Much easier to get the stuff in before joining the aft section to the main fuse.
Randy

Well, I too am now 4 engine qualified. I was falling behind in posting the remainder of the building photos, but I think this is more interesting. The Baltic Air National Guard.

Hang onto your seats! It weighs in at 22 lbs dry, 23 1/2 lbs wet. O.S. .32 sx's with my custom made flying 4-bladed props. Need 15 degrees of flaps to lift off, but she's got good power. Lands very easy at a nice high angle of attack at flare just before touch down. Four succesful flights. Needed about 5 clicks of up elev. trim. I think 2 deg. negative would have been just right. I had put in the -1.5 deg. in the stab. but it's good enough. Thanks guys and also Jim and Randy for the great tips.

Wow, lookin' good Gunny! Glad to hear the flights went OK. Weather here was absolutely perfect today-temp in low 60's, not a breath of wind. I got several flights in on the Herk, and possibly the best landings I've ever made. I still like shooting touch and go's as much as flying it.
Congratulations on a job well done.
Randy
