I run on indoor clay and they definitely dont start working til they break in but once you get to that point they perform pretty well

arms, shocks, towers, cvd's, turnbuckles, chassis, battery strap, might have missed something..better off to sell it..IMO

better off getting a t4...the only parts that you can use off your b4 is basically the steering/front bulkhead and the tranny/rear pivot. You would need to buy arms, driveshafts, shocks, chassis, shock towers...etc

track isnt dusty unless we dont sweep for the day, hard packed and almost similar to a clay feeling when nice and wet at nite time. Double dee green compound should work well according to maifield the the track is hard packed and dry or wet and loose. IDK ill get back to you guys on that.

I know I've read about changing the B4.1 chassis to the T4 chassis to lengthen the wheelbase.

Can I use a T4.1 to modify the B4.1 or does it only work with the T4 chassis?

Thanks

That will work fine if you want to try it. the main difference between a t4 and t4.1 chassis is the material.

My buddy slammed my B4.1 into a curb and busted the chassis, thought this would be a good time to try the T4 out.

Oh, what body fits that I read it somewhere a while back but don't remember.

You can use both but I would stick with the T4.1 chassis since it is made of the same composite material as the b4.1.

Edit: got beat to it lol

FTW Nightfox Xl body and Jconcepts J82 body.

I think someone on here used the proline bulldog for a b44.1

You can buy a FTW Night Fox XL body from Avidrc.com. That body will fit a B4 with a T4 chassis.

Thanks for the link, that is ugly

hopefully the bulldog B44.1 body fits...

B4 Chassis -vs- B4.1 chassis

Are there any differences beside material in the 2 chassis?

I found B4 chassis on-line but not to many B4.1. Don't want to go the T4 route, just had a body painted not to long ago.

Thanks

It is probably a b4.1 chassis. The part number didnt change with the .1, it was a running change. ASC9560 is the part number.

the b4.1 has taller sides to hold the larger lipo battery packs..that what ive heard..im to lazy to actually measure it but they are pretty much the same
