Learning to tune .21 size motors..
While the OS motors mentioned above/below are great motors, I would suggest a motor that can handle a learning curve. The OS motors cant handle getting hot very many times, but the RB Concept motors being made of harder material hold up very well as learning motors. They also make great race motors.
I suggest:
RB S5 L2G with a JP-3 pipe. This is a good race package at an economical price.
Expert level race motor:
RB WS73 L2G also works well with JP-3
