Its very fast, i wonder what motor and esc and batteries he's running there.

That's no normal BX huh, on his car the rear belt is under the rear brace... It's not like that on my BX! :confused:

[Chaz]

Wow, that is one nice off-road track, that makes me wanna race off-road :cool:

I really wonder how he got his rear belt under that brace, and why should it be better?

[Bastos]

I think the position of the rear brace is "logic"...(ones of billy)

The brace , I think, is too much closer to the chassis... in case of "strong" flexion,..., it could brake ( I ever break this brace ) because the brace got the same flexion of the chassis
Better if the brace is higher.

[Marco]

would be interesting to see Details of that Mod

If you look closely you will see that he mounts the self made rear upper deck NOT to the shock tower base, but to the rear bulkhead (BX-302RL and BX-302RR). Doing so the upper deck moves higher (with the help of some bushings in the front and rear) and the belt is entirely under the deck. You can see these bushings in the front (silver) quite easily at the end of the video.

I mounted a stiffer rear shock tower on the BX after a crash landing. After that the shock tower didn't break any longer, but the rear upper deck started to break (not once but n-times :o). Actually the BX is the first car I ever had which breaks the upper deck quite easily. The good thing is that Billy Easton seems to have experienced the same problem ;). The reason seems to be that the impulse of a crash landing is directly moved forward from the shock tower to the tower base and finally to the upper deck, which might break if the shock tower did not (as Bastos already mentioned). With this mod the impulse which goes into the upper deck is reduced since the flex of the bulkheads should be less than the flex of the tower base...

Hope someone understands what I mean (english is not my mother tongue)?!:confused:
