If you're trying to do a flying wing, you'll need a radio with elevon mixing. You might be able to get away with dual vertical stabilizers mounted on either side of the servos on the outside and without rudders. There are commercial motor pods which you can use to point a pusher prop rearward.

Is that a scratchbuilt of yours in the photo?

Are you trying to make a flying wing out of an elevator or are you trying to install the elevator on a model?

Tell you what: I need to log off, but go ahead and send me a private message telling me what you're attempting to fly and your skill level. Let's figure out what you need to get airborne. The best advice I can give you is to simply learn the basics when starting out. You don't have to try and invent an airplane. That part's been done for you.

Good luck and stay in touch.

I don't think you'll have a lot of luck getting that to fly being a flat section. Flat wing planes fly well with a tail, but tailess it's a different story. You need a good wing section like one with reflex. i.e. the trailing edge kicks up. I've tried flat wing tailless planes and haven't had much success, but with a good wing section they fly very well.

I just meant a conventional plane with a wing and tail. I built this 163 without a tail and just couldn't get the plane to pitch up to keep it in the air without the tail plane added to the back of it. People do make flat wing deltas so I assume that some do fly but I still think a plank like yours doesn't have a lot of hope. If you want to build then find a plan for something that works. Perhaps a delta wing?

While you don't really need to know aviation terms in order to get started in the hobby, it should be clear as to what the "tail" is.

If not, it's simply the rear of the plane. It's sometimes referred to as the "tailfeathers" just for fun. It incorporates the horizontal stabilizer (the thing you want to try and fly), vertical stabilizer, rudder and elevator.

Check out this link from NASA:

This is a random Google link I found with a search for "model flying wing:"

http://www.rcplanet.com/ProductDetai...FQuCQgodMXYAcg

That swept-back shape is pretty much standard for any flying wing. It also needs an airfoil as another poster just mentioned; a flat, rectangular shape isn't going to fly.

Cam, that won't work. You're not going to be able to simply sand an elevator into an airfoil.

All you're going to wind up with is a lot of wasted time and sawdust. By the time you were to get the electronics you'd need, you're going to be out a lot more money than you would be if you bought a ready-to-fly model.

I get the impression that money might be an issue, especially given your age.

You actually have a better chance of getting that little display kite of yours to fly, but I don't recommend it.

I also don't recommend that a raw beginner with zero time with an R/C model even attempt to fly a flying wing. They're more stable than many designs, but they are by no means for beginners.

You do get credit for showing an interest in a very fun hobby. Beats heck out of video games. That's from someone who grew up with them starting with "Pong" back in the 1970s.

Take a look at the blog entry of mine linked below. That model may have been free, but it is by no means ready to go without throwing cash at it. It will need servos, a receiver, a receiver battery, a new fuel tank, new fuel lines, some rectangular hardwood stock for new servo mounts and assorted new hardware. My suggestion is not to go searching for a "freebie" like that since you haven't the money or the skill to get one flying.

Again, you'd be wasting time, money and material.

Please save yourself the frustration. Start by contacting your local hobby shop. Tell them you're interested in learning to fly, you have no experience and you'd like to visit a local club.

They will fall all over themselves to guide you.

I don't know how much longer you're going to have suitable flying weather in Wisconsin, so consider an indoor model such as a coaxial helicopter. Easy to fly, easy to fix and you learn how the sticks work as well. They're also relatively affordable, which is important since your income is limited. DON'T blow your money on a convenience store toy helicopter.

Someone at the club might even have an old model they'd be willing to let go for a few bucks...or even give it to you. Just don't troll for freebies.
