| One suggestion. The manula give some Swash AFR rates to strat out with, somehting like 60%, -60%, and 60% (I don't recall as I'm sitting here in the office checking finishing up some paperwork.
anyway, depending on the servo arms you installed, this is what i used on my flippy-floppy Tiger setup. 20mm arms on the two aft swahsplate servos and 23mm on the forwardmost servo.
Then after selecting SR3 and making sure the directions of the servos were correct, I used subtrim to precisely center the servos at neutral position (mid-stick). I used 88% for both aileron and elevator and 48% on pitch.
I then dialed in the amount of elevator and aileron by defelecting the control stick and watching for where the bottom of the swashplate would "almost" touch the main shaft, and then backed it down a tad for clearance. by the way, check this in both directions and if it touches on one side before the other, you need to mechanically adjust linkages, but remember, to go in one turn on one side and out one turn on the other unless it's in the fore-aft in which case you adjust both aft servos in, then the forward servo goes out and vice-versa. Anyway, this give the max cyclic pitch (or throw). The collective pitch works out to 10.5 degrees and -10.5 degrees at 18% at point 1 and 82% at point 5 (yes, I now fly a symmetrical setup). I use this in both bormal and Idle 1 (and Idle 2 for that matter though it's an exact copy of Idle 1 in case I flip the switch to far). Then in the hold condition, I crank up point 5 to 92% which translates to something like 15 degrees of positive pitch for when I really blow an auto and need desperaste measures!
There's more to it, of course, but that should get you going in the right direction. I suppose it's time for me to make a new update to our R/C Basics: Hover video both since I'm now flying a symmetrical setup, and because while the 6X and 6102 radios are still available, they have been eclipsed by the very capable Futaba 7C at the lower end of of the price curve . . . that and I've just not had time (or the place) since Hurricane Charlie destroyed my studio where I film (witness the last modelSPORT was released way back in September 2004 and I've "still" not been able to release a new issue since). Oh well, at least nobody was hurt.
