I actually thought that was DickyT's truck for a minute when I saw the battery, lol.
Turned out really well.

Im pretty pleased so far. Im working on posting a video right now. just ran it for about 5 minutes.......lots of wheelie's

I also did a few high speed runs but none on film.

temps seemed to be fine.

motor and esc around 100
batt around 120

Hey thanks man.....
AZJC sent me a link to another site that had them in stock also.....

I have one on the way.

Just made another video.....wheelies and back flips mostly....will post it soon

Having a heat issue though.

4s 8000 lipo................................100-120
mamba max esc (w/fan)..............150-175
Feigao 7xl...................................200-225

im running a 40t spur and a 15t cb
any suggestions on changing gearing??

Im hoping the 8xl will help with temps.

you have it geared pretty low, I think the higher turn motor will help, but also heat is something you get with the Feigao motors

I have read the link in Brian's signature......about being over and under geared.

So just so i got this straight......under geared = high spur...low pinion
over geared + low spur....high pinion

is that right?

[BrianG]

It's not necessarily specific to a pinion or spur, it's about overall reduction ratio. Tire size even affects gearing (sorta). If your motor speed is fast, but vehicle speed is really slow, then that's undergeared. That can be caused by a spur too big, a pinion too small, tires that are really small, or any combination of these.

are you talking about "roll out ratio"??

you want the roll out ratio to be as close to 1 as possible right?

here is a video of some back flips.....

How is the side to side weight balance with that huge battery on there?
