 __Knez 289 points
Where to get 4mm pinions ?!?? All motors have 2,3mm shaft or 3,17mm shaft or 5mm shaft. Where ot get Motor pinions for this motor?

can you tell me if it will fit in a 1/16 traxxas e revo vxl ?
 xjohnx 23 points
I'm afraid this is a 540 size motor, then it won't fit your revo's stock motor mount. But it's possible to install 540 motors in the mini-revo, bu using the TenBol motor adapter
 Arthur 23 points
According to the specs that says 28 x 48mm it is the exactly same size of the velineon that comes with the E-revo VXL.

It is not a 540 size

Iam getting one of this for my own mini revo!!
 __Knez 289 points
This is not 540 size notor. As Arthur sad 28 x 48mm.

Could be a great 4s motor for a Wemotec Minifan or a 3s motor for the WM400 fan. But why is HK still rating those motors with max 7.4V? Seems to be senceless. Noone needs such a motor...must be a mistake. I hope so.
 panxgtsb 318 points
I don't think the motor can handle 4s, even if it do, the max amps is 58. a 70mm fan with a 4400kv motor the current would be more than 80A. for 4s and 70mm the kv should be 3200-3600. I believe that this motor can handle 3S.
 Wilhelm 255 points
My friend is using a HET 1w30 in a Minifan at 4s. It works at around 65A But you can reduce the trottle and fly with less amps. It works. 4s and 3600rpm is extremly lame. Sorry. We tested it.

Wilhelm, i can't figure that at myself about the 7.4 volt thing-I do know there are no advantages with lower voltages in terms of amperage as oppossed to higher voltage.

Got it as a freebie. No idea what to do it. I payd a little extra shipping for it so maybe I construct a car or smthng.
