Frequently Asked Questions
What is the difference between the RMX 4 RTR and the RMX 4S PRO kit?
This is the RTR version — assembled, tuned and fitted with electronics; just drop in a battery and drive. The RMX 4S PRO is an unassembled chassis for those who want to choose their own motor, ESC, servo and gyro.
Is it suitable for beginners?
Yes — the factory setup does not depend on your tuning knowledge, and since it is built to competition spec, you will “outgrow” it much later than a budget RTR.
What do I need to buy separately?
A 7.4V 2S shorty LiPo, a compatible charger and 4x AA batteries for the transmitter.
Can I fit a different body?
Yes, as long as the body’s wheelbase matches the chassis settings. Whichever version you buy comes with that body, but you are not limited to it.
The RMX 4 RTR sets a new standard for ready-to-run drift cars: a sensored brushless system, professional gyro, metal gear servo and a competition chassis — you won’t “outgrow” this car anytime soon. Grab it, charge it and send it sideways.
