Mamba Pro maybe toast?

[Alcrawler]

Start with Mamba Max Pro deceased heat sink removed (I know heat sink there for a reason but it wouldn't fit) smashed up with BEC and receiver. Problem is after couple courses I loses drag brake in reverse never lost it forwards. Then if your just playing around it will quit like you lost power. Cools down starts working normal then lose rear drag. I've had this setup for about a year worked fine till now. Thought someone may have run into this.



Been looking at Homes Hobbies TorqueMaster BR Mini may need to get one on the way.
