Have Fun!
I like the 7XL on 14 cells best. Seems to be quite efficient on 14. Occasionally I run 16, works well too.

Thanks dafni, do you run your gearing 18/66?

Yepp, 18/66 for small tracks with lots of partial throttle, also works fine on gras, and I always keep it on 18/66 when I run 16 cells. This gearing is also great for bashing around.
20/66 for those big tracks (which I still have to find in my area :W: ) and parking lot sessions. And I think for speed runs, you could still go a bit higher.

Theoretically, 18/66 (1:18) and 14 good cells should give you 35mph. (KV rating from BK, stock tire size)

Optimal gearing depends on weight and other factors, too. So no two trucks are identical. Motor temp is a good indicator for finding proper gearing.

Yeah i just go back from my 14 cell run and yeah its fast enough for me. The temp on the motor never got above 160 degrees, which is a huge change from the 9L. I think so far i like the 12 cells for bashing because the run time is so good and i think i'll stick with for 14 cells if i ever go to a track someday. My truck is weighing in at around 9 1/2 lbs so not heavy at all.

Sounds like you like that motor there mike d. You thought you would.

Yes i do. Its seems like the 7XL was meant for monster trucks. The 9L and even 10L seem like they struggle to push the emaxx and the 7XL does not even hesitate at all. Runs cooler, better run time the only downfall is that its not as fast.

I ran mine with 18 cells. It was getting the job done. I need to get me another one on truck. If not fast enough just add more cells. :lol

Well this is the setup I'm likely to go for now. :)

Changed my mind between these; 9L/10L/XL2800 and looking at the 7XL, its what I want for runtime, speed and room to upgrade on cells. Still think the 7XL is the right choice? :D

@nick..

I don't see another option which is that cheap, that suits all your needs..

The 7XL not running hot, means it runs more efficient.

dollar for dollar it is hard to beat the 7 xl. IT has power decent run time and it is only a few more than a long.
