RE: Ultimate setup
Mr. Krayzc: I'm an IMAC pilot in the Unlimited class, and this thread is in the IMAC section. So my answers will be favoring set-up for IMAC flying. I set up my plane to the snaps at full transmitter stick deflection of the gimbles on all three axis (airl, ele, rud). Every snap is done the same on the transmitter by way of full stick deflection. I then play with the length of the servo arm and length of the airleron arm so I get the desired airleron throw while the ATV on the transmitter is at 140 % for airlerons. This way I'm getting the best mechanical advantage that the servo has to offer, less gear wear, less case wear, less battery usage, less linkage slop, less chance of flutter, I could go on and on ....... I set this up to give the desired roll rate for the snap. I DON'T roll the airplane at full stick deflection, I roll the plane at partial stick deflection. I know, I know, this contradicts what I posted. However in the Unlimited class we have more snaps than rolls, and snaps are harder than rolls, so I better let the transmitter help me with my snaps. In some cases we snap the airplane 17.5 times in one four minute flight. To get the feel I want when I do a point roll (the airlerons will be too sensitive for partial stick commands set up this way) I add expo until I get the "feel" I want at smaller stick inputs. This way I don't have to hit a rate switch for snaps. All my sequence flying is done on the same rate as far as airlerons are concerned. The elevator and rudder only have about 10-12 degrees of travel in them each way. This keeps the tail "quiet" while flying, and helps to hold the tail behind the nose.
I change models in my transmitter to fly 3D. It's impossible to fly IMAC and 3D on the same model memory at the unlimited level. I have two model memory's stored for each plane. One is call Yak-IMAC and one it called Yak-3D. One can't fly 3D with 10-12 degrees of tail throw. Conversely, one can't fly IMAC with 40 degrees of tail throw.
Hope this helps,
