Suggest you review the posts in the Global Electric motors sub section of Golf Carts NEV’s etc. This has been covered many times.

I have spent hours looking at site and can not find this. could you please give me link to area i need to be looking. I found where you told one guy to look at 5models but could not find that either. Thank you in advanced.
