RE: cox electric cl
I honestly don't know as I have never even seen one myself.
I will say this, the battery is probably no good at all and even if it were the more moderen batteries of today are much more powerful for the given size and weight.
The same can be said of the motor.
However its flight charactaristics were then could be easily made much better by replacing the battery and notor.
I have no idea what would be appropriate however.
