Jammin X-1 CRT motor selection

[BrianG]

If you want something that will work at both 4s and 6s, I'd get one of the LMT motors. As BP-Revo pointed out, the coils can be reconfigured from D to Y by some solder pads on the back of the motor. This will let you run 4s when in D mode, and 6s on the Y mode and still run at the same total RPM.

However, at the cost of an LMT motor, you could get three XL motors with different kv ratings for whatever voltage range you want. The XL motors are good too, just not as efficient so they heat up a bit more. As long as you keep the bearings clean and make sure the end cap doesn't pop off (use the RCM heatsink/clamp), there's no reason why an XL shouldn't last a looong time.
