This is a big project. Big with a capital "B". This thing is a monster! Bigger than anything I would have imagined when I first viewed her on Craigslist. I'm not sure what people on the forum have done in terms of calculating the amount of electricity it would take to propel something like this through the snow. I'll report back what I find in real-snow conditions.dumbass said:Let me be the first to tell ya that is one cool vehicle. Not sure how it's goingto take to being an electric but it is cool. Gotta love the dual tracks and wheels too. HAve to decided what motor (motors) you will use?
It has two clutches that allow individual braking for each track. The brakes are in the front. I've considered putting two motors on for tank like steering but to start with I'll stay with the original design and use one motor.FrankG said:Are the tracks going to be driven in unison or independantly, like a BobCat skid-steer?
I'm not sure if I have the:FrankG said:As to sizing the motor, What displacement was originally installed, even though there is considerable variance between ICE and Electric motor specs, it would be a starting point... If you're going to retain the the gearing of the drive train, at least you'll have an approximation of the RPM/HP range you'll need to make it fly.
I'd be happy with very happy with the 15.4 mile range. It would be a nice goal to have mine operating by the competition in March (even though I can't enter) it might be fun to take it up there.litespeed said:Not sure if it's helpful but I found this......http://elitepowersolutions.com/snowmobile.html

Registration Team Limit = 25 teams
Registration Cost = $500.00
Believe me the thought has crossed my mind. I'd love to make it into a robotic sled with tank drive steering. I already own one controller from Roboteq and I have two Eteks in original boxes!AmpEater said:That thing is just begging for a pair of eteks. Chain drive to each track, they would probably remove more weight than they add. Plus double the peak output of the engine.
Very cool. Never seen one of those before

You may be sorry with one motor. Those clutches/brakes are notorious for being a pain after the sled has sat outside for a few months. There are two of those sleds in our local club. I think they are both 440 cc. Great fun on a hard packed flat trail. Useless anywhere else.
