That was my thought when they announced it was going to use the 2200kv - with all the bad press Castle has received over the XL, they don't need more because of idiots who think they can gear that thing any way they like and not bother to check temps.

Yes, I've looked through it quickly a couple of times - and you've been working overtime on that build - really nice. When I get some time I'll look through it carefully and maybe get some ideas for my next build - I have some crawler/scaler parts that I bought recently, and hope to do something with them sooner or later.

I had this out again today and it ran well - I'll post a couple videos in a bit. My only concern is that this truck tends to roll over much more easily than my other large-scale build. This has a slightly narrower width, it's center of gravity is a bit higher due to the body, and it has better tires (more grip in the grass) - all of these I'm sure contribute to it rolling over more, so I'm not sure what I'm going to do. The major advantage of this truck over my buggy-style build is that this has more room for batteries.

I could easily make the truck wider by using the full extended wheel hexes (instead of the cut-down hexes I have on this). I'm sure that would help, but I don't know if I'd like how it looked.

Or I could run it w/o the body (but I know some people didn't like how it looked under the body).

If you have any other ideas, let me know.

Videos:





I had some better jumps off the lip of the infield than we got on this video - but here it is anyway:




Edit:
Temps (outside 85F) after approximately 15min run:
Motor (Castle XO-1 1717) - 160F
ESC (EZrun 150A pro) - 145F
Batteries (2x Gens Ace 6s 25c 4000mAh in parallel) - 99F
Center diff - 135F

The batteries were not completely drained (probably 3000mAh used in each). This esc/motor combo on 6s has plenty of power and seems like the perfect size for this truck.
