How come I see some M03's with 2 motors? Is this custom or just a different chassis?

Our cars now weigh close enough to 1500gms...and ask Drifting 101 how fast our cars are.... Less weight isn't necessarily more speed...

I build in a 3400 Lipo (Orion). I just attached it firmly with tape and I intend not to use my NiMh-stickpacks anymore.

And so I also did the lipo-mod as bescribed on Mini-net, ading weight within the body. It weighs now around 1400 or even more with body and transponder ... never had any problem keping up the pace with lighter cars, even when running mabushi.
The extra weight helps the traction of the wheels. They spin less.

There are some weighs within the bumpers and on top of the battery which I can remove if nescessary, but until now, I have never felt the need for this

May be a stoopid question but is there much driving difference between a gear diff and a ball diff. Made the switch over the weekend and my car seemed really twitchy coming off slow corners...or is all about even better throttle control.

did you build the diff as per instructions?

Is there still diff action?

It should be identical except you should get a bit more pull out of corners.

Make sure you have some foam bits or o-rings in the out drives so they stay in the splines and don't slide out, the ball diff splines are much shorter then the normal diff. Also make sure what ever you use in the outdrives that it doesnt bind the drive train as the suspension moves up and down and spins around.

Yep built as per instructions, used orings inside the outdrives to stop the axle moving round....do i need to use o-rings elsewhere....the diff still spun freely, first time i ran it there way no drive. Rebuilt it again and away it went. JUst comes off the corner real wierd until it gets some speed up and away it goes....kinda like having torque steer in a real front wheel drive.

well if the outdrives are not coming out then I don't know what else it could be.

What ride height do you run the car at?

Something that can affect how the car comes out of corners is the steering links getting cought on the chassis when the ride height is to high, make sure the ride height is fairly low and the steering links are level to the ground.
