HYPER GO R3B Receiver for H14MK, 14301 and 14303

About this brushless motor

The twelfth and fourteenth scale boards are not interchangeable even where they look alike, and the mounting tray is what gives it away: this one sits under the deck of the 14301 family. We keep it listed against those model codes rather than by scale so the fits row does the checking. Bind it to your transmitter after fitting, and route the aerial up and clear of the pack.

Where it sits in the HYPER GO RC car range

The R3B is part of our Motors, ESCs & Radio Gear shelf, which carries 11 parts for the MJX HYPER GO range. Model code R3B 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 H14MK, 14301, 14303. 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 R3B

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.
