The problem is still there. After 2-3 mins the turbo/supercharger function is gone and intermittently coming back randomly. We also notice that while the turbo/supercharger is gone the red light only illuminate when in full throttle, not the usual red to green lights.

Anymore suggestions to trouble shoot this problem? Or can I just advice my fried to send it back to Hobbywing for repair and if so how do we send it back? Whats the procedure?

Thanks.
