You boys are correct, losi 8ight motor support (LOSA4462).
When I remove the motor next time I'm going to file a few fins down so I can slide it under the motor more if not completely.
My Hyper9E heatsink support is F.S. ? PM if anyone is interested.
Heres a couple pics of how the body fits. Not perfect but definitely a ton better than most I've seen.
