Evan, I was not able to pull full throttle due to lack of traction. I was over half throttle, though and had to let off in an attempt to keep it fairly straight.
Norbert,
I was using a Lehner basicxl 2400 motor and 18.5 volt (5s) LiPo batteries. What driveshaft are you breaking? A wheel shaft (diff to wheel)? I was actually using the stock plastic sliders on the e-maxx we are speaking of. My truck is just under 8 pounds RTR, though.

I am constantly breaking the MIP front drive shaft from the transmission to the front diff. I tried using the plastic ones and I snapped them on the first run. Start to twist a little but snapped and the base where it connects to the yoke.

I use steel dogbones in the center. For the front, the Monster Pirate front center dogbone works.

Thanks Mike. I have to keep an eye out on ebay. My LHS hates ofna therefore they dont order or stock ofna.

Probably any front 1/8 buggy center bone would be a close enough size to make it work. The Monster Pirate is a reworked 1/8 buggy from years ago.

hey Lou has the track running counter-clockwise now.
If the double on the straight is still in the same place you'll have 2/3 of the straight to build up steam. I wonder where it will touch down now?:-)

It tends to drop fast after it hits the ceiling!

well maybe with 40MPH of forward momentum it won't go up twards the roof so soon.LOL!
I just may have to get one...Hummm:-)

If there is less pitch on the jump, I am quite sure I can land in the pits!

I accidentally took out a lightbulb tonight with the gmaxx. HotnCold and I both put on a little show with brushless LiPo power and we have a little video as well. It should show up in the video vault in the next day or so.

what lipos do you run on what chassis (guess gorilla carbon)

The truck I ran is a generation 1 purple G-maxx chassis with a Lehner basic xl 2400 motor and 5s Kokam 3200 LiPos.

Alum Gmaxx chassis, 10L, 5s 3200's, busted a$$ revo rims.... Man those revo rims looked nice but didnt hold up very well....

anyone have a prob. with the traxxas e-z start?

it turns over fine but will not start any help please.

Noise
 

First off - welcome to the site - I have yet to start my Revo yet - so the noise you are hearing is new to me - however - there are a lot of people who are at work now - so later on in the day - im sure you will get an answer for this Question...
