Hi all!
I found Durafly's EFX race's architectronics is very similar to my originals.
I don't wanna claim though, I should have to say mines are the original before five years ago .
Anyway carl-up wing tip functions avoid tip stall.
Fuselage and cockpit design is almost the same, but mine is cooler, I think.

Huhuhu
