'Lumpy' Orca 6.5t Brushless

[Dudders]

Guys,

Had an issue with my C4.1 on Thursday night. For the final, upon warm up the car was stopping quite quickly, I had assumed the mess/motor was off and was too tight. I ran it anyway and it was really like driving with a full on drag break!.

Taken it all apart today and the mesh was fine. I reduced all the speedo setting to base (no drag brake etc) and it's still stopping quickly.

Taken the motor out and the motor when running is very lumpy and almost feels as if its become unbalanced, if there is such a thing?.

Motor grumbles rather than whizzes. Any suggestions? It's aboiut 5 months old and only really raced indoors.

Thanks in advance,

Neil
