Had this idea for a flexwing. I had this thought that you could use the booster/engine weight for the balance, not drop it off.
Created this nose piece and 3d printed it.
Attached to 18" spruce spars.
Lightweight ripstop nylon.
Fits in a BT55
The rubber band across the nose spreads the wing.
The wire pieces pulled out, so I used staples for string and rubber connector.
Nylon glued to spars with titebond.
hinge pieces glued to spar with epoxy.
Thread to each side spar to limit degree of spread.
I think the nose and the metal screws are a little heavy, very nose heavy glider, but if I add about 8g clay toward the rear it does seem to actually glide. I found I can order smaller nylon screws. I'd like to try those.
I did lots of reading and know that the cg for a flex wing should actually be about 30% from the front and about same distance below the wing.
I had this idea to actually use the booster as the balance weight, slung below the flex wing. I have some ideas on how I might do that, but I want to move on and do some other builds to free my mind for a bit.
So this post is just to share what I've got so far, I need to take a break from this for a bit.
