HYPER GO E45K2 45A Smart 2S/3S Brushless ESC

About this brushless motor

We list it on its own rather than calling it a variant, because the lead lengths are what decide whether a board sits flat in that chassis, and the wrong length is a hot wire bunched under the upper deck. Cut off is set from the pack it sees at power up. If you have stepped a 1/14 car from two cells to three and the old board has started cutting early, this is the part.

Where it sits in the HYPER GO RC car range

The E45K2 is part of our Motors, ESCs & Radio Gear shelf, which carries 11 parts for the MJX HYPER GO range. Model code E45K2 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 H14BM. 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 E45K2

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.
