Default Finally started my experimental Airplane... Check this out.

Here it is...the "wingspan" is about 40" wide... Right now I have my OS 46 FX mounted in there...the muffler is downstairs.. The fuel tank, throttle and rudder servos, batteries, and reciever will all be mounted behind the enine. The back part will have elevons and a rudder mounted.. The elevon servos attach to the support spans that attach to the engine.
I still have a LOT of shaping to do on the airfoil which I'm not looking forward to doing.
Let me know what you guys think!!!
I can't wait to get it done and try it!

It looks like more than a "start." I'll be watching to see how it progresses.

Looks like a flying eye! Can't wait to see how it turns out.

Is it going to be hand launched? Where will the CG be? What kind of shaping of the wings are you referring too? It may fly as it is.

My roommates and I call it the flying pink taco so far... I have yet to shape the airfoils into it.. CG, not sure, probably start with 1/3 from leading edge. Right now I'm thinking of hand launching... I will see what the 3D capabilities are and see if I can land it in a hover. Not sure how much it will weigh yet but I think it's fairly light right now as is. I need a power sander to shape the airfoil into a halfway decent airfoil then I'll probably give it a go.. No sense in wasting tons of time on something that might crash right away anyways.. We'll see! I'll keep you posted.

Did the "flying pink taco" fly yet?

It may be easier to use a 'hot wire' foam cutter to cut the airfoil [except at the glue joints]. That would trim away a lot of the excess quickly, and avoid the sanding mess.

Update...Still haven't worked on it in a long time.. Waiting to be laid off from work to start working on it.. That happened today so I'll get around to it.. I'd probably rather maiden this thing with some snow on the ground to soften the landing if it's not flying so great.
Still have to shape the airfoils but I have the aileron servos mounted and the slots cut for the hinges.. Other than that I'd say only about 20 more hours of work before it's flight ready.

Hi Love2FlyMN
On your maiden flight I suggest you keep it very close to you. With no tail, I believe that orientation is going to be a severe problem.

Hi iron eagel
What you posted is hardly different from a standard Biplane. The other thing is closer to a flying wing which have their own characteristics. The CG on a flying wing is much further forward than on a conventional configuration.

so would you consider putting the CG at about 1/4 the way back from the leading edge?? I was shooting for 1/3 the way back

I'd start 20% back from the LE of the pink.

As soarrich said, you want to stay more forward with a flying wing COG. Upwards of 15% of MAC is not uncommon, start with it forward if elevator is not that effective move it back in small increments till you get the response you want. Flying wings tend to be a bit twitchy as far as pitch so starting with a forward COG is the safest way to deal with them.
