In Mode 3 the rudder stick controls the direction and speed of rotation with the throttle at neutral. So if you apply a little rudder then the motors turn slowly in opposite directions but at the same speed. (NB: By “opposite” I mean that one goes ahead and the other astern – in practice this means that both motors will actually be turning either clockwise or anti-clockwise, assuming that you have the conventional counter-rotating props.) This will have the effect of turning the model slowly about its own vertical axis. Add more rudder and the speed of rotation increases. Introduce a little throttle and you will bias that rotation so that the net effect is to move the model ahead a little in the turn i.e. if ‘forward’ then the model will describe a very tight circle instead of turning on the spot. The more throttle then the wider the circle. Hope that clears things up for you (even though it’s a pig to describe in words). The easiest way to find out is to buy one and try it…….…….just like over 1000 customers have done. One guy has bought eleven of these!

Everything P94 does is proportional to the stick movements – this gizmo is far more than a straight substitute for two microswitches on top of the rudder servo.
