Will (Flywilly) and all others interested.
My friend has his Top Star flying now.
It flies great.
No pull to the top or bottom in knife edge flight and only slight aileron coupling with rudder. He is currently flying it without any electronic mixing at all. He says he can trim the coupling out without having to use a mix.
He's flying the new FAI sequence with it.
Spoilerons on final really slows the plane down well.
I'll try to get a picture when I can.
