Went flying again today, i have put about 10 flights on since the carb trouble and no other issues since then. I have taken out all the upthrust and find that it flies much better. The vertical is very good and the plane will do hovers, harriers, elevators, walls, flat spins are ok (CG should go back a bit, better inverted), snap rolls and spins are really good as well as the traditional aerobatics.
