Castle should make the overvolt protection switchable in the setup menu. That way regular users could leave it on and retain the warranty coverage and the rest of us can switch it off and pay the fees if we cook it. Hell, they could even have different charges for repairs if it was switched off. Personally if I cook one trying too run to high gearing on a heavy vehicle it is my fault. I have had excellent service from castle on a lot of their products and never had a charge from them. Anyway, the 50 bucks should cover their cost of an esc. Just my 2 cents, can't blame them for cvering their butts
