RE: retiming ? on GWS EPS-350C-DX
I did a little experimentation with my 350C in a C gear box. I used 2S 2100 Li-Poly pack and a GWS 9x7 prop. Stock I got 4500 RPM at 6 amps. I retimed it using my amp meter and 2 AA batteries. Stock the 2 AA's pulled .65 amps (no load). I turned the back plate about 4 mm clockwise till the amp meter read .78 amps. After connecting everything back up, I got 5000 RPM at 8.5 amps. I hope this helps. It sure gave my Mustang some extra zing.
