Well all answers are good.As far as dihedral needed for a rudder turn to bank the wings imagine this. Left rudder input causes the right wing to go faster than the left and produce more lift and produce a roll. In level flight a aircraft must prduce 1g of lift anymore or less will cause it to climb or descend. So in aturn this 1g is vectored into the turn direction even without control input to maintain height the aircraft will do a descending tun. Remembering that the primary effect of rudder is yaw and the secondary effect is roll. A 60 degree banked turn requires 2g to maintain level flight. To work out a planes stalling speed at 2g you get the square root of the g(2) wich is 1.4 times the planes clean stall speed, no flaps.At 55kts times 1.4 gives a stalling speed of 77 kts, under this speed the aircraft will stall and drop. This is true with models and full size. So when pulling massive g`s out of adive with a big heavy model watch out for the high speed stall on high rates. By the way this stick position will be the same at any speed and if your ever there dont pull more ease of up the gass or again your wings wont save your tail! B-2 is awesome
