@Firestar119 - Your poll... should it be "unlimited video games but no bacon"?

Since the last Flite Fest, I've been thinking about designs for a better combat wing for FF '25. Since my last wing had its fins damaged during combat, I started experimenting with finless wings and drag rudder yaw control shortly after the 2nd prototype of this combat wing. The newest iteration, v3, boasts a 72in wing (with 3d printed wingtip extensions), removable wing sections, and dual use drag rudders that can be used for yaw control and braking. Since my FF '24 wing took so much time to assemble, I decided upon a much simpler Flite Test style airfoil and box spar system.

Had a VERY hard landing after misjudging a turn
No damage to the airframe, only the motor pod

Too bad...Glad it wasn't worse!

 

[Firestar119]

The plane is pretty overweight and sluggish on turns, might need to cut some weight from the spars or electronics (wrong)
Or add more thrust (maybe?)

How did it fly?

It needs quite a bit of speed to stay airborne, but its very stable and has enough power to pull straight vertical very quickly

Nice!

I went to fly the wing again today, this time with a GoPro in the wing and more elevon mixings for the airbrakes. It seemed to fly better than the first flight despite the added weight.
I got around 18 minutes of flight time with two 1800mah 4s batteries and a bunch of high speed passes.
