I have been stalled on this project for quite a while now http://www.pirate4x4.com/forum/showthread.php?t=450342 and have been considering different motor options. There are the usual options but space/length is an issue. Electric motors have interested me for along time as a good fit for trail use. The on demand power, weight distribution advantages and near silent running tempt me to give it a try. I think a torque converter and a high quality control would be important. What might some of you with knowledge in this area think? http://www.cloudelectric.com/inc/sdetail/590
Thanks, Tyson

Thanks for the input, all of these are valid observations. The weight of the motor and batteries is substantial and must be balanced against power and range concerns. I like the ability to position this weight almost anywhere I want it and was thinking I wouldn't need much more than a fifty mile range for most extreme trails. One thing that concerns me is the shaft diameter of most electric motors. The shaft does not look strong enough for shock loading but must be rated for motor output? This is one of the reasons I am thinking of coupling the motor via torque converter. Maybe if I think about this long enough the advanced motor and battery technologies will become more readily available and make this application more feasible. I must admit there is still something inspiring about the rumble of a big block though!
