My First Try At Designing My Own Plane

Here is the first try at Designing my own plane. I hope it flies !

I drew it out on paper and me and my dad scaled it up from their.

If you guys see any problems with the plane please tell me so I can fix it before I instal the electronics.

The goal is to have a nice little 3D Foamie ...

I am going to add SFG's to the Wings eventually ...

That'll fly. Balance it on the wing spar. Make sure the ailerons move an even amount up and down. I'd go for a bigger rudder, but why not try it as it is and add more if needed.

Test gliding the empty airframe is always good ... Use a lump of clay on the nose to find the best CG ..

hi there from Toledo

I think that you will find that your Hstab and elevator is on the smallish side, areawise. Try for about 10% to 15% of the wing area.

Start with a hand toss glider version. Build a few Hstabs for test purposes. Start big and then reduce The Hstab in area until it doesn't fly right, then choose something in the middle of the range and go with it for the r/c version.

Haha James I can't tell you how many planes I've drawn in class that I'd love to actually build but never have. Cool to see you taking one through all the way. Maybe I can make it out to the field soon and see it fly. I drew one today I really like. Maybe I'll make an attempt at building a prototype of it this weekend.

It's a cool design but I agree the stabs seem a little small.

It did fly ....

It had some problems ... the motor was off slightly so I had a couple rudder trim issues .....

The rudder and pitch authority were fine .... and the roll rate was very good

But its very heavy for its size due to the doubled fuse sooooo when it stalls .... its going down ...

Next try will be without the doubled fuse and a Blue Wonder motor ....
