..electricDave is working on a better alternative. We don't think the present one will be financially viable, even though the gearbox itself works really well. The problem lies with the original c5motor - it just isn't really up to what we want to achieve,even in 24v format with maxxed out controller. Voodoo's performance at this years AER simply highlighted the problem.
I don't think any of us would be happy paying big money for a conversion that causes damage to the motor in the long term.
This detour means we may take a little longer, but it will be worth it.
