I've used some of their stuff on other kits and never had issues with them. Fit and finish was acceptable.

Yeah don't believe the people saying kyosho is superior aluminum etc. Its quite close with the strc stuff. Kyosho stuffs been known to fail as well the hubs, the front hinge pin brace etc. I ran strc stuff (front spindles, rear hubs and hinge pin holders) on my rb5 and it was great. Sadly they don't have wider hinge pin holders.

Lol. I still have a b4. Might even sell my 22 and give my kid my b4. At least I could use the same wheels front and rear.

hhmm... im not sure actually, let me take a look.. BRB

EDIT: It looks like I used 2 spacers... a fatter 2mm one, and a skinny 1mm one? It doesn't matter really, as long as the servo fits forward and clears all the plastic. Space it so the mini-steering turnbuckle is as straight L to R as possible.

Great choice of servo too, btw... the BLS line from Futaba are the best servos I know. The 551 is just perfect.

Here is a pic of my servo spacing... kinda tight and dark, but I brightened it up so you can see... you can make out the 2mm, and 1mm spacers

so I put a savox 1258 in my rb6. One small issue, how do I get a full pack in the car? I have a shorty, but I was thinking of also trying my full pack to check the feel. I put the rear battery box all the way back. and out the long pack in and its sits on top of my servo, lol. do you not use the rear box at all?

You don't use the rear battery box with full lipo, it just sits up against the tabs on the lower bulkhead.
