ORIGINAL: Whirligig Hi, My Aurora 9 was very easy to setup for a Fabco Tigercat parkflyer with twin electric motors. But there's a 200 to 300 rpm difference between the two motors that I'm trying to trim out. This difference appears from low to high thottle. What I would like to do is trim out the difference by assigning a trim tab to adjust the speed differential. Is there a way to do this? Thanks, Whirligig
Use two separate ESC.
Settings> [MDL Type] > Single Engine.
Settings > [Channel] > Ch* <span style=''font-size: smaller''>(say5)</span> > AUX1> Sel (switch) :RT.
[Model] > [P.Mixes] > 1. ACT > Ch3 > Ch5 > [Select] > switch G & T.App : ACT> end.
NB: Before Turning Model ON
Settings > [Model} > Monitor > (opens Monitor screen) and watch what happens when trims are adjusted.
RT provides a much wider trim adjustment and user will need to observe overall effect on ESC .
Tie model down and range check running & trimming both motors to ensure operation is correct over full range.

Alan,
I needed to revise the step in red from your instructions and that is to change the H: Rate and L: Rate to +100 while in the P.mixes. Without that, the rates to the program mixes are initially zero and in Monitor mode there is no response from Ch 6 until a rate value is put in. This really had me stumped until I figured it out. Here's the revised step:
Revised Step: [Model] > [P.Mixes] > 1. ACT > Ch3 > Ch5 > [Select] >
Rate H: +100 > Rate L: +100 > switch G & T.App : ACT> end.
Thanks,
Whirligig
