mmp works great on the 3800, only issues I've read were with ballistic 550's. I've run mine with the tekin 550 4.5, as well as 540 sensored with out problems.

my problem is that people having issues with the sidewinder.
i have a vxl that as been work flawless on every motor i used with it, even with novak 5.5 hv with sensor connected worked good but in this case for the 4 poles one form castle some people say canīt work good. the hobbywing one i was thinking is this: http://global.ebay.com/HOBBYWING_EZR...510793116/item i had several good experiences with previous versions of these escīs and this is half the price of a mmp. regards |
The ESC really can't tell the difference between a 2-pole and a 4-pole. 1 rotation of a 4-pole looks like 2 rotations of a 2-pole. I don't own a VXL, but I don't see any reason that it wouldn't work on a 4-pole motor.

the vxl is 200 amps rated and witout any motor limits so i will give it a try!

It can make a difference if the now doubled RPM's exceeds the rating of the ESC.

The rating it might exceed is the maximum rpm racing on the controller. The ESC can switch the poles up to some maximum rate. If you hit the limit you motor just doesn't go any faster. With a 4-pole motor, this maximum switching rate translates into half the RPM that it would on a 2-pole motor. So if some controller can run a 2-pole at 100,000 rpm, it can only run a 4-pole at 50,000 rpm and a 6-pole at 33,000 rpm. This was a bigger problem when brushless controllers first came out, but I haven't seen an issue with this in several years.
i will try than and see how it runs! regards |
Have you had a chance to run the 4 pole motor with the VXL ESC? If so, how did it go?
