Coolhand, what 2250 turn do you have? What vehicle do you run it in? And how many volts?

I'm probably just gonna buy a wanderer, but if I get the dough I'll buy the 2250.

And if there is too much power with the 2250, why not use like a 30t pinion gear (from kershaw)?

a 2250/10. there is quite some difference between the XL and the 2250.. :p

I have a 2250 10t. I have a center diff to lower the final drive ratio to 10.5 to 1. I have ran a few cell counts on it. It is awesome. It is way more powerful than a 7xl. The torque is unexplainible. I love it.

Do you have any pics of your prodject ?.

CHC- dude, how did you put Mulchers on 40 series wheels? cutting the bead off? I got to say I wish they would make the mulcher in 40 series. I want some.

Too long to mount easily, I would need a mount that was extremly strong, even then it may flex and strip gears, and what do you upgrade to when you start tearing up 1/8 diffs?:027:

Nothing to show yet its all still pieces, I will post as soon as progress is made.

I would be satisfied with about 60 mph, I dont think I would actually go 60 mph often, I just want crazy acceleration whenever I lay into the throttle. Big power and speed is more important to me but I want to be able to put that power to the ground, thats why I chose the crt, less rolls wheelies and flips than the emaxx.

are these the shafts you are talking about? These are the optional ones, they are alloy, I beleve the stock are steel, I am not certain. I may try to find them in titanium or get some made in tool steel if they are a problem.

Also is lightweight and handling more important or big power and straightline speed.
For a racier 40mph setup i'd take a 1940,mount it above the spur in the centre and move the batteries closer to the centre line to lower the yaw moment.i think that would be the best handling.
For heavier motors,i'd mount it low beside the spur,due to the weight of the motor.
A 1950 would do mid 50s i would think,beyond that the 2240.

I'd be a little cautious about the alloy bevel shafts in the Jammin,i guess any BL motor will test these though.
Edit;nl12,since you have access to a machine shop it would be easy to run off a set of steel bevel gear shafts on a lathe if the alloy ones become a problem.
