im not sure as i have a x1 and i used the hotbodies ring and pinions from the lightning stadium pro. had to do some shimming but they are solid diffs. i would assume the x2's would work but im not 100 percent. but the hotbodies are cheaper, at least they were when i was shopping and hot bodies parts are easier to find by me.

I got the truck and have torn it completely apart. I've started with rebuilding the diffs. I have about 2-3mm space between the ring gear and the chassis, so not much room for a larger ring gear. I'm assuming truggy ring gears are larger than buggy ring gears?

The truck has been completely rebuilt. Instead of changing all the diffs, I only changed the center diff with a ravager diff with 51t spur. To stay away from gearing too high I decided I could keeps rpm's low. I have 3 options:
- Neu 1521 1.5y @ 8s : 31080rpm
- Medusa 80m1100kv @8s : 32560 rpm
- CC-Neu 1518 @ 5s : 33300 rpm

I'm not quite sure which way to go yet....

R u racing or bashing? If racing 5-6s is more than enough. I m using neu 1515/3d on 6s 5000 zippy, 50 slip diff n 16 pinion which gv me 37mph.

8s will be too heavy, 6s 5000 is already heavy.

Btw my car is a x1 CRT with x2 gearing.

Bashing only. Why would 8s be too heavy? I'll probably run 8s3000mah if I go for 8s. With the Neu 1521 on 8s and 13/51 gearing speedcalc's output without ballooning is 39mph.

Cost bro! U pay more for more Cells n C rating. The more Mah n cells the cooler the system will run. U also need slip diff if not your gears n cvd will wear out fast ESP with so many cells.

So your car is heavy, wear out faster n can't have long run time.

The cost and weight are about the same!

With the 1521 1.5y I would buy two turnigy 4s3000mah40c packs
weight: 720gr
cost: $76.52

With the 1518 I would buy a single 5s5000mah40c pack:
weight: 704gr
cost: $76.82

Good luck to ur insane truck:) the wear n tear rate will be very high ESP u hv so much power wo slip effect.
