JJKWANG,

Very nice work. Do you know what current the motor is pulling?

Thanks,
Keith

I'd also like to know how suitable that GWS motor is for RFFS airframes.

Nice job BTW.

JJ,
That is very nice. I think you have the 2-cell RFFS combination down very well now. You have another winner here.

Tiberius,
I think the GWS motor he's using is essentially a N20, which is about right for that weight and size plane on two cells.

Thank you for kind words and interest. Keith and Tiberius, I hope below link helps you(You can find the B2C data table on bottom of the page). The GWS B2C motor is similar to the hi-volt N20, but it has carbon brush.

Thanks guys. The M20, N20, HV, LV, UHV combinations still confuse me. The B2C would only be suitable for 2 cell applications. The RLC motor looks ok for 1 cell use, but that amp draw is too high for the RFFS, right?

LV=low voltage
HV=high voltage
UHV = never heard of this - maybe ultra high voltage?
N20 = M20 lookalike, a little less powerful as I understand.
M20 = that's what the KP00 uses, that's what an E-charger motor essentially is (slightly different windings)
M20-HV is the most powerful of them all, and it can be run on one or two cells.

Hello, Michael. How have you been getting along? Thanks for advice.

Tiberius, Yes, the RLC motor draws too much amps. This motor is not suitable for the RFFS-100.
