Talking about Rx-41 and Rx-81, there are different versions. Initially the production started in China, but two years ago Tecnitoys (SCX manufacturer) brought the motor's production to Spain, and modifiying several little aspects improved the quality, gaining rpm, brake and torque. There are no external differences between both versions, so it's not obvious know if a motor is made in Spain or China.
There are also a "pro Turbo" version of both motors, same structure than classic versions but at 18.000 rpm.
