I don't think it is lower. This is a really wide truck (almost square if you look down at it) and lands nicely when jumping. I would say it may even have more clearance and shock travel than some 1/10 trucks.

The stock rims are buggy 2.2 rear rims. You can, however, run the wider 1/10th truck rims with no problem also.

I am still waiting for my lipo from maxamps. I ordered it on 7/20 and it still isn't here. I have not ordered from them before. Do they always take that long?

$120 for servo-you could save some money here.

So if you look at it this way its $700, but you can go to a lesser servo or do what I did and steal the servo, radio, and mamba from a previous car.
nitro28,

Nice job on that conversion!
What's the pitch of the hardened 14t pinion and where might I source one?
Does that pinion mate with the original spur gear of the CRT.5 Pro?

Enjoyed the video and pics, thanks very much.

The pitch is a mod 1. It does work with the stock spur. You can get the hardened pinions from:

http://www.rc-monster.com/gears.php

Use the 5mm pinions because they are hardened, then buy the $5 bore reducer to make it fit on a standard 1/8 motor shaft. 14t is still a little tall for a mamba system. If you use a torquer motor you can play with the gearing a little more, but the mamba probably would work best with a 12-13t. I have seen gearing as high as 20t with a big lehner motor but its kV rating is much lower so you do need higher voltage lipos.

Yes I did make the mount. The stock mount as you know only takes a mid size servo which was too weak for me. I really like the airtronics 94359 servo. New its $120 but you can get them on ebay for a lot less. They are super fast and 200oz. Any full size servo is about the same size and should fit, I would suggest a torque rating above 100oz minimum. I used some aluminum sheet to make the mount and the bolted it over the servo using some stock holes in the chassis. I then just used the stock linkage and flipped the ball stud on the bell crank up on top.

Right now I am running a little hot on the esc with the lid on. The motor is 130 F and the esc is 155-165 F. I need to cut some vents for the esc's fins. Also I probably need to drop down a tooth on the pinion.

Ok i just ordered the 7700 because no where has the 6900 and i have a heatsink for the motor with a fan on it and a spair fan i will mount on top of the esc trying to cool down the temps...i will only be running it on 6 cells so it really shouldnt be too much of a problem, do you think?
