Rebuilding a B Max
Hi all
I'm totally new to the RC world and recently bought a used B Max. I have a few niggles I want to sort. I have had excellent advice from Si Coe, but I don't want to be pestering him 24/7  This car is just mainly for bashing at the moment and I would like to make a few changes. What cheapish shock/spring combo's are there that fit the B Max? Also I have a bit of play in the spur gear (looks like a buckled wheel). It's causing quite a bit of vibration. What steps would I need to take to remedy this, bearing in mind it will be all new to me Any help/advice would be much appreciated.

Hi, b max is a cracking car. It's hard to advise on shock springs etc as you say you only want to bash with it. If it is standard plastic shocks you have on it then an easy upgrade is Associated B44 or Losi xxx cr shocks. Associated springs are easier to get than the Yok ones. As for the spur gear. when you say a buckled wheel, i take it you mean the spur gear is damaged? You would have to replace it. They are really cheap and you can get them on ebay. If you were to post some pictures of the problem then we may be able to help you further.

It will be hard to take a pic of, as I can only see it when it's moving. Like it wobbles when rotating.
They are not original shocks, I think they are losi ones. I think the car is more set up for racing, but I find the back too soft and would like to stiffen it up slightly and riase it.

Looking at these on ebay at the moment. The shock I have on aren't adjustable. Would these fit?

Jaw, the spur gear problem could be the spur holder/ bearings. First thing i,d do is see if the whiole slipper/spur gear assembly has any play in it. Grab both oudrives of the assembly and move it in every direction you can. While doing this, is the spur gear changing alignment (not staying straight)? if so, you could have a problem here causing this vibration. If all looks great at this point, disassemble the slipper and place the spur gear on a flat surface to check for evenness. If the spur isn't straight, that's the problem and is a cheap fix.
For the shocks, I'd buy a new set of the Yokomo shocks (the plastic ones), that way you're sure they are 100% compatible. But id the Losi shocks fit, why not use them? It is for bashing after all...
