Problem with 1/10th TC

[Jamesd]

Hi

I am posting this on behalf of a friend.

My friend is running an Xray TC with GM120 from 2009, with a 13.5T motor and lipos.

He has a problem with it. He will start the race with turbo then after a short time (this can range from 1 lap to 2mins) he will loose the turbo effect on the car and the car will become very flat when throttle is applied. The motor is not getting to hot. We had somebody at the club check the speedo settings and they seemed to be ok. We thought it was the servo causing the power loss but we changed it and it was still doing it.

Any advice would be helpful.

James
