Default RE: Trimming Out Twin Motors on an Aurora 9

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 &gt; [Channel] &gt; Ch* <span style="font-size: smaller">(say5)</span> &gt; AUX1&gt; Sel (switch):RT.
[Model] &gt; [P.Mixes] &gt; 1. ACT &gt; Ch3 &gt; Ch5 &gt; [Select] Rate H: +100 &gt; Rate L: +100 &gt; switch G &amp; T.App : ACT&gt; end.

NB:Before Turning Model ON
Settings &gt; [Model} &gt; Monitor &gt; (opens Monitor screen) and watch what happens when trims are adjusted.
RTprovides a much wider trim adjustment and user will need to observe overall effect on ESC .
Tie model down and range check running &amp; trimming both motors to ensure operation is correct over full range. -
