Description

PROPDRIVE v2 motors are designed to perform right out of the box with tight windings, smooth bearings, correctly rated magnets, precision cut stator and balanced rotors.

 

We design and build the PROPDRIVE v2 motors completely in-house allowing us to control every aspect of production. We control the entire production line from material sourcing to machining, balancing and final assembly. PROPDRIVE motors can be trusted to provide years of reliable service at a price every modeler can afford.

 

We have included a collet style adapter, as well as a bolt on prop adapter.

 

All performance figures are the result of realistic testing on our own motor dynos.

You Can't mesure KV by reading 2 of the 3 poles of AC current. To read KV correctly. You must use bridge rectifying diodes to all 3 AC poles and convert it to Mono static DC current. I read 880KV on a 2 pole AC measurement as well. With bridge rectifying diodes to convert
the 3 phases of AC to Negative and positive DC current I measured around 520KV or 1.9 VDC at around 1000 RPM's. Dude if you have the skill to rewind the coil learn how to measure it right. The motor is spot on with great bearings. I use to think like Christian. Wrong ways to measure

Hi,

motor looks good. nice build quality and pretty good winding.
The no load tests at 10V showed a kv of 880, not 500. That's far off. I'll probably rewind this motor. It is a 12n14p motor.
