WPL 3CH Speed Change Gear Box And Radio Transmitter For B1 B24 B16 C24 1/16 4WD 6WD Rc Car
A part of the review has been auto-translated.
The controller is excellent, very precise and with a lot of adjusting possibilities. Receiver is standard and works fine. Gearbox works well, but this is the older version with a spring for returning the lower gear back. This is sometimes not much reliable as the spring is quite weak.I changed the original plastic gears to the metal ones (also bought on Banggood) and it helped a lot, but the gearbox is noisy now. I installed the whole system to WPL B36 and it fits perfectly, without any modification needed.
Easy to use and easy to install, excellent for WPL C24-1, channel 1 for steering servo, channel 2 for esc, channel 3 for speed change servo and connected the front lights to the 5 volt output that the receiver has with a 1500 ohms resistor. In the receiver you can reverse the channels and set speed limit. The motor didn't have the connector
