I've gone the HiMaxx 3618/4500 and planetary gear box route and wish I had put the $160 into a big AXI instead. Much better choice for what I wanted. Not saying the HiMax is a bad motor. I burned up a PHX 80 trying to run the motor direct drive with an 11X8, 9S pack! Well over 100 amps with no dammage to the motor. That was before I learned to use the Whatt Meter every time I tried something new!

I'm very happy with the AXI 4130 on 6S, (9S is much better!), with 19X8 EAPC in my 60 size E-U-CAN-DO. Should have gone that way in the first place. I'm running 6S3P till I can afford a 9S3P pack as the amp draw on 9S2P is too much for the batteries.

I suggest the big AXI.....You'll never look back!
