Ill let you know what my settings are, you can use the info if you wish.
First my normal mode is set so the revmax is off (50%) and throttle curve is as it normally would be with out the revmax. this is my "safe" mode so if the gov is setup wrong or i throw a magnet or it just stops working i can flip to normal mode and still have control.
second i have iddle up one and two set as 3d modes just two differnt settings on gov percentage for two differnt speeds 1900 and 2200 rpm head speed. my gov settings are normal 50, idle1 79, and iddle2 84.5%. on both the 3d modes my throttle curve is 100% across the board so the revmax does all the work
make sure when you calibrate the revmax that your throttle curve is temporary set to 0 25 50 75 100, the trim is all the way down, and your throttle atvs are close to 100 each way. then set the curve back to normal.
I recomend that if you do the 100 percent curve that you have the gov set to just above off at like 55 or so to start. and spool up on the ground to see if it works then slowly rotate the dial on the 9c up to a normal flight rpm checking with a tack (somebody else runnig the tach though)
