mamba max problems warranty policy ?

[v1d9uy]

ok so a friend bought a mamba max about 3 weeks ago and now it wont sync or even be recognized by any computer and it wont work all the lights just stay on he called castle and they agreed something is very wrong they said he had to send his esc in and then they would send a new one out ? is that right i know iv read on here a few places where someone just called in and castle sent out a new esc with a package to return the old one ? that sounds a lil to good to be true but i was just wondering...
