I have a problem with my CMPro KATANA 140 : when I do hard manouvers with the elevator, such as polling-out from a dive, or doing a strong negative-G loop, the wing drops like crazy! I can't realy say if it's allways the same wig, but I think it's the right one.
I checked rolling balance on the ground and it was OK. alsaw I checked both elevators (who have the exact same servo type) and they move perfectly equal, both "free" and with presure on them.

Please assist. I'm afraid of loosing the plain doing low manouvers... [&o]
