RE: Rimfire / Multiplex Cularis
As long as you take, with all the grains of salt in Siberia, the suggested amp/watts limits for the Rimfire 35-30-1250 [35A/333W... get a grip!]. In my testing I found that the motor could cope with 25A... maybe a bit more... but it didn't like anything close to 30A, let alone 35A; at those levels it was unable to hold amp draw or RPM, and attempting to fry itself.
On 3s it did well enough with a 10x6 GWS HD, but a 10x7 APC E was a bit much, and an 11x5.5 APC E was over the top.
At 71g, and applying the 3W/g rule of thumb... 210W-220W is okay... maybe push it to 250W... but I wouldn't go much further.
