Also on the brakes im not really sure how other people feel about the current setup for these cars, i watched a few races with these puppy's and it seems they use the brakes to help rotate the car in the corners and i have no need for this feature so i locked the fronts to help control braking from higher speeds. so it may not be for everyone but it sure tames the car to be driven like a normal car. just my few marbles

Ok then...how did you accomplish this. With my mrx-4, if I tap the bakes just a little to much, I am in trouble

The bearing size is 10x6x12mm for these cars i looked for a while for a bushing this size with no luck and then i was forced to make them but now i have options so tomorrow ill have some bushings made. I will be thread locking the bushings then drilling then tapping and ending with a grub to lock the wheels.

Is one of those motors in the last pic much fatter than the other or is it just my eyes playing tricks on me?????

I had a machinist press a fitting inside the hub which in turn eliminated the one way bearing and allows me reverse and motor bakes. Eventually I am going to eliminate the AL bottom battery brace and replace it with carbon fiber...

I am running a 1800kv on 6s and it flies...haven't quite dialed in the esc for a little drag brake, motor brakes yet but working on it. The first time I took it out I almost totaled the car..missed a concrete light stanchion by inches doing 50mph+ This is my first true on road car as it has a learning curve as I only have been running in the dirt

Thanks for that pics guys. This is going to help immensely with my Serpent 960 conversion I think I am going to do the batteries the same way as you did magman. I hope I can get some 4-5mm thick carbon fiber plate and make like a wide pan chassis so that the batteries can fit on the sides of the chassis. I think that would be the neatest and easiest solution (posibly the lightest as well). Do you guys think that 5mm thick carbon fiber would be ok for the main chassis (bare in mind it will be a lot wider and hold the lipos on the sides)???? Once again thanks the pictures. Great help.

Magman is running a CC1512 1800kv. The shorter can size in a small space does play tricks on your eyes a bit.

OK, that's what I was thinking. The next motor in size up (diameter wise) is the 1717 and that would be just plain crazy in one of these things.
