what pinion would you suggest i use?
maybe a 20 or 21 with the stock spur. Then check motor temps every couple minutes to make sure they don't start to spike over 150 or 160.

Has anyone ran black springs on the rear? I cant find any. Is it normal for the rear springs to touch the camber linkage? Please share any tips you have come up that only requires work not buying anything.. cya in the pits.
Check the spacer on the bushing on the top shock mount screw. Maybe turn it around. I know mine used to rub more with the lunsford titanium turnbuckles than the factory team turnbuckles as they are a bit bigger. For optimum performance it would be best not to rub at all.

the used roller i bought came with no servo horn.
i tried to use one from an academy buggy but it sticks out from the servo to far.
the servo area is rather small.
am i missing something? or do i have to use an associated b4 specific servo horn

actually i figured it out...
i should have noticed tbh.
the braces that hold the servo to the chassis had a small shim in between the brace and the screws.
removed that and my academy svb2pro horn works perfectly.

its night and dark so i can only drive this up and down my driveway but i cant wait to try this thing out on a track! seems very zippy!

The speed difference probably won't be an issue unless on a very large track. The motor temp would usually be more a concern. Just keep an eye on it. Brushless isn't like brushed. They work in a range of gear ratios but too high can be as bad as too low for temps

The stock spur should be 81t, so a 19t pinion should be fine.

Gold springs for that one. Its a really good setup for high bite. I think it worked better with the weight of nimh though, especially on high bite clay tracks like trackside. The new FT T4.1 setup is really good too. Been running it all year with a variations at diff. tracks.

Question for you associated guys, I picked up a new b4.1 and on the rear shocks the green rear spring rubs against the shock body no matter how I trun the spring on the collars. I usually wouldn't mind but it does rub pretty hard on the body and can tell a difference in the two shocks. Anyone have a fix for this problem? Thanks.

Yeah both of my rear springs rubbed real bad out of the new kit. Take some sandpaper and sand the high side off the bottom of the spring. Do one side at a time. The color coating was real think on mine.
