Need some info from those using an electric reverse.

I have a Sylva Phoenix with a 07 Fireblade fitted. I have a gear between the diff' and the prop shaft.
The question is..... what would be the best motor/starter motor to use, weight/power etc and fitting/operrating method?

Photos would also be a great help.

Is it to satisfy race rules or do you want a reverse that you can use regularly in the real world?

This thread might help,

the problem you have is most starter motors spin the wrong way
mk have theirs altered hence the price
ive done some searching in the past but never found anything
so i now make sure i have a passenger with me when i go out in the car
