Hi MrGerbik,

The roll of the plane is a function of several factors. The ones that you can most easily control are the degree of deflection of the ailerons and the speed of the plane. If your transmitter allows you to choose low rate and high rate for the controls, you will find the plane rolling much better on the high rates than on the low rates. Basically, the slower the plane flys, the slower and slopier the roll will be. If you fly your Trojan at 50% throttle and have it set to low rates, you will get a very sloppy roll. If you fly it at full throttle and have it set to high rates, you should get a nice crisp roll. When a plane banks, the wings provide less lift than when it is flying level, so the plane starts to loose altitude. For this reason a little up elevator is needed when a plane banks into a turn to keep it flying level. A roll is a bank taken to the extreme, therefore a plane is naturally going to lose altitude during a roll. If you angle the plane slightly up when you begin the roll, the impact of the lost lift is minimized.
