Botbitz 85a esc..... in a heavy?

[overkill]

Marto custom programmed a TZ85a to act as a one way weapon controller for me, so it can be done. The problem is that you don't get all the FETs conducting at the same time; the most you can get is half of them IE all the high-side or all the low-side. It increases the current capacity but not by a huge amount.

Ah that's what I feared. Could you have the same setup with the external relay h-bridge then use one of these for the pwm control: http://uk.rs-online.com/web/p/igbt-transistors/7917422/
