Rolls — The Triplane can be rolled but this maneuver gets difficult due to the differences in the control sensitivities of elevator, aileron and rudder. The best way seems to be to use high speed entry of 110, nose up 30º, full aileron and hope for the best. Lots of rudder correction is needed to overcome the adverse yaw. Once the roll starts indiscriminate use of the rudder or elevator will quickly stop the roll with some interesting results.
The best rolls seem to happen when you use very little corrections once a roll starts. Big barrel rolls also seem to be better than rolling on a point. Slow rolls are very difficult because of the control sensitivity. The bottom line is, keep it fast and quick with lots of altitude for corrections if you fall out of one.
Ah! And here I thought it was just me who was falling out of a roll...
The Triplane was constructed by Gary Shepherd and myself over a 2 ½ year period taking 3000 manhours to complete.
Geez, no wonder the Germans were always short on airplanes...
