fly boy2 -> Foam combat plane (4/6/2008 4:46:00 AM)

I am trying to finish building a plane and I would like to build a cheap foam combat plane to help pass the time. Something that can be build in a day or two, and cheap to build . If anyone know of some plans or a link to a site.

Also, take a look at TufFlight, they make a number of planes that are designed to really take a beating, and fly quite well.

You can do a search for the FUNK on the forums. Made form 3/4" pink insulation foam. If you want something with a real airfoil I've built a plane with foam core wings and a coro fuse. Cheap and light. I haven't maidened it yet, but I plan to next weekend (travelling a lot lately). I'm planning on offering kits with CNC cut foam core wings for $45 bucks. Let me know if your intersted. Look a few posts back in RC Combat for twin tail SSC design. Chris

If it does fly which it looks like it will, is there anyway you could shrink the 60'' span to a 30'' or smaller and do you think it could be ran with a brushless motor?
Good Luck with maiden flight.

Fly boy2,

Well the maiden went great! I could shrink it to a 30" span. Shrinking the span won''t cut weight that much but it will increase the wing loading (stall faster). For a 30" wing it would probably make sense to cut it as 1 piece. I can do up to 48" on a single piece.

What size brushless are you looking at?

Chris




fly boy2 -> RE: Foam combat plane (4/19/2008 12:48:56 AM)

Well first can I ask you is this? How well does it handle, like a noob or a novice can fly it, cause I'm still a bit in the beginner stage. and I really don't know what size of brushless motor or any kind of motor , I guess a motor that it pretty cheap. lol I might have a few R/C cars I can take it out of. lol [:)]




batchelc -> RE: Foam combat plane (4/19/2008 12:41:15 PM)

Flyboy,

I wouldn't really know too much about converting a car electric motor to airplane R/C. I'm sure it can be done, but you would have to delvelop everything. The plane that I have designed uses a cheap 0.15 glow motor (60 bucks new, 30 buck os ebay). Electrics are going to cost many times more than that for a moror, batteries and speed control.

I flew the airplane again last night. I added some differential to the ailerons (one goes up more than the other goes down) and some additional vertical fin (rudder) area and I am much happier with the way it flies. It's very stable and could easily be flown by a noob.

I'm not sure that scaling it down would have the same flying qualities. Smaller airplanes tend to be twitchie.

Its a 4 channel right. Can it go in inverted and do a snap roll? Do you have a video of the flight, if so can you sent it to me?

It's a 3 channel (ailerons, elevator, throttle) so no snap rolls. But it's easy to fly and lands slow. It can fly inverted and requires some elevator to stay inverted.




Montague -> RE: Foam combat plane (4/21/2008 3:18:42 PM)

You don't need a rudder to snaproll, you just need enough elevator. A rearward CG helps as well. My SSC class planes will snaproll if I use ailerons and elevator, and yes, it's a real snaproll, not a barrel roll.

But if you're looking for nice acrobatics, you do need that rudder. Of course in combat we generally try to avoid snaprolls




fly boy2 -> RE: Foam combat plane (4/23/2008 1:16:37 AM)

how much do you think you will sell it for? and it it assembled except for engine and radio when you sell them




batchelc -> RE: Foam combat plane (4/23/2008 3:23:37 AM)

Flyboy I sent you a PM. Chris
