2S Scratch built profile foam sheets tape etc.
2 Cell scratch built from foam board, tape, glue and things like that.
No plans no pattens. If it looks like an airplane it should fly, right?
198 grams. 24 inch wing span. 2 cell battery, 15 minute flight time.
Flew today first time. It's a keeper!
I have flown it maybe eight times now. It is quite stable for what it is. The control surfaces are large enough to do rapid rolls and tight loops. It uses a variation on the KFm2 airfoil so there is a touch of self righting. The short wings provide good lift but a bit of wobble when you try to hover. It can fly quite slow in low wind conditions.
Overall it is a surprisingly good flier, definitely not for the beginner. Not for windy days ether! I may trace it out and provide plans later.
