I recently bought 2 mid sized elec planes, about 48 - 50 wing.
An extra 300 and a Katana.
first flight on sat,......issue, extra suffered minor main gear damage due to full stall at no power, CG seemed to far to rear, Katana however, seemed to be correct in aspect of CG, Has more then enough power with 15" prop, seemed to fly relitivly well, even as shaken and nervous as i had become.
My question is this......a plane with this config, are they naturally unstable and touchy?
What can i do to tame down and stabilize flight characteristics ?

Thanx
Bob
