Yes it is worth it. I've driven both short and long chassis cars back to back. I did notice a difference in stability. Now I gotta get to the hobby store and get one.

If anyone looking for RCRD +8mm B4.1 chassis
http://www.rctech.net/forum/r-c-item...assis-new.html

Umm.... I will have to see if I can work up some money to try it

so now the track is being wet on a daily basis and the recent setup doesn't work well.

Somebody throw me a setup thats working well on wet med high bite clay.

New tires, broken in, bald=push, loose.

Idk what happend. My diff is getting gritty so I will rebuild that but i dought
thats what it is.

tried brent theilke surf city setup. It didn't feel much to good.

surf city is for blue groove, go back to brown green springs with stock weight oil and use Trinity bomb 1 foam 1512 in rear.... you will thank me later

im going back to stock. Stock links and all just 8mm chassis. And I will c what local sponsor is doing. Damn were gold barcodes slippery when it was wet

hey guys,
Is there any way to stop the rear tlr springs rubbing on the turnbuckle?

make sure using the short black ball stub #3983 on rear hub

Nothing wrong with your set -up , look into what the other guys are using for tires & traction compound.

ok also ganna smooth out my speedo, i had it agressive when it was higher bight, not its to agressive, its all sorted, I hope I can go rat at the track and test this out.

Prob ganna buy a new b4.1 kit my is clapped. Its still fast tho=]

I think it was my speedo that did it, viper stuff is great tho tune that out and im set.

cherry what setup u run? and ill stick with this but im wondering..

Thankyou, im just using the ball stud's that came with the kit but ill order those ones soon.

What's the difference between normal pistons and drilled pistons Cav is mentioning in his Vaasa setup? Are them 3 hole pistons with #55 holes?

#3983 are the ones that come in the kit

Anyone care to chime in?

Scanned a couple hundred pages of this outstanding thread, but didn't see anything much on "wobbly wheels" - apologies if I missed the answer to this noob question:
I just bought a B4.1 and I notice that most of my wheels have a wobble that could only be described as Wagon Queen Family Truckster-like. I don't know if a good amount of wobble is normal, but it seems like it would cause wear and tear to the bearings, drive linkages, etc. My kit is 3 days out of the box, 100% stock right now.. is there a mechanical cure or was this a bad glue job at the factory or...? I've taken the wheels off and put them back on, no real difference to report.

Would sure like to get my tires and wheels tracking straight and true - any help would be appreciated greatly. Other than that this car kicks ass! Much respect to those who've posted here, there's a TON of great info.. look forward to going from total noob to half-decent noob soon.
