The IBC has such a wide range of voltage because its not just designed for featherweights, it can be used in lightweights and possibly some small middle weights. IT can also cater for those who wish to run the motors on higher voltage ie: ww motors on 36v

The main reason why the IBC is so dear is because it has MOSFET reverse instead of the cheap less reliable way of using relays like in the Electronise. Also, the failsafing in the IBC is very good, maybe too good, I was rather dissapointed when i saw that my mate had payed out AUD$250 for a 30amp electronise to see it have no real failsafing :sad:

Anyway, Ive got two IBCs and I love them, but I guess its each to his own. Also Joseph, most speed controllers that have mixing have it done in the microprocessor programming, not via circuitry
