HYPER GO E45M 45A Brushless ESC with Heatsink

About this brushless motor

The twelfth scale cars carry more weight and more gearing than our smaller trucks, so the board spends longer near its limit — which is why this one is built around its heatsink rather than having one added. It is a plain speed controller, not a combined receiver, so a failure costs one part and not the radio link as well. Wiring is the usual three to the motor, two to the pack, signal to the receiver.

Where it sits in the HYPER GO RC car range

The E45M is part of our Motors, ESCs & Radio Gear shelf, which carries 11 parts for the MJX HYPER GO range. Model code E45M is the number every listing here is keyed to: quote it and the gears, shocks, wheels and bodies that suit this chassis all line up. It is a service part rather than a vehicle, so check the fits row before you order.

Fit and compatibility

This part is listed against H12Y, H12P. Those codes are stamped on the chassis plate under the body; photographs are a poor guide at this scale, because neighbouring versions differ by a couple of millimetres and look identical. If the plate on your car is unreadable, send us a picture with the shell off and we will tell you which version you have.

Living with it

Electronics fail hot. Blow the heatsink and the fans out after dusty sessions, keep the wires clear of the spur gear, and give the car two minutes between packs in summer.

Specification

Questions about the E45M

Will this fit my HYPER GO RC car?

Match the model codes in the fits row above against the code stamped on your chassis plate. Brushed and brushless parts are not interchangeable in either direction.

Does it need setting up?

No. The 45A speed controls read the cell count when you plug a pack in and set their own cutoff. Receivers are bound with the transmitter held close to the car.

What if the car powers up but ignores the handset?

That is almost always a lost binding rather than a failed receiver. Rebind both units together before ordering a replacement.
