Default b4/velineon gearing

picked up a B4 and put a velineon setup in it and believe it has a 84 spur/24 pin......that sound like the right combo??

Hi,

Can someone point me towards a good starting T4 setup, indoor, high traction, clay? I have a plastic truck.

I had an older one from Bridgewater, I think my wife through it out with the trash by accident

Thanks

i need a good outdoor med-low traction lightweight set-up for my b4 and t4. when i try to run you guys set-ups from ur high traction indoor clay set-ups my cars push like crazy. im thinkin its in the roll center up front and possibly some other tweaks need to be made. thanks

B4 = blacks in back with 4th hole on tower and inside hole on arm
bronw spring up front, middle hole on tower and inside hole on arm
bumpy track = 25wt #2 in front, 30wt #1 in back
smooth track = 30wt #2 in front 35wt #1 in back
Longer camber links would help you gain traction so play with that for your track. use tires everyone else uses at track.

T4 = stock setup should be fine, tires = what fast guys use at track.

Thumbs up AE Is Killer Of All......

Hey slick why would you be running the light weights in the front and not the rear?

to soak up some of the bumps when when you steer so you dont loose traction, thats what i have run and it works on all tracks, even the carpet trck that i run at. ive tried different things, and that seems to work. and it makes it more responsive in low traction.

Default T4 RS Race Spec RTR

I am getting one of these for my son, and was just wondering how the servo it comes with holds up? It will only be used for bashing.

Default 5000 Lipo fit into B4?

Old racer here, getting back in. Just bought a B4FT. I purchased two 5000mah Lipo packs - a Thunder Power 40C and a Reedy 35C (ASC709). Neither of the packs seems to fit into the rectangular battery compartment "box" at the rear (under the rear shock tower) - the packs go in maybe 1/4" but then stop. I'm able to use the Thunder Power one with the battery in essentially a forward position, but I can't even get the battery hold down brace into the rear compartment (under the lip) with the Reedy pack (the Reedy pack is slightly thicker than the TP pack).

I've looked at a number of B4 setup sheets and it seems most times the battery is run in the "front" position. So, maybe I don't need to worry as much about getting the battery to go back to the rear (although it seems that might be a nice tuning option to have, as the chassis designers intended it with the older Nimh battery cells). But, I'm still confused as to how I can use the Reedy pack. With the Reedy pack, are people just not putting the hold down under the rear compartment lip (i.e. holding down the battery with just the front posts), or is it necessary to modify either the hold-down (thinning it out), or remove material from the underside of the rear compartment lip to make room for the hold-down?

Thanks for any thoughts or advice.

you can remove material from the underside of the tray. i just put the strap on top od the lip and call it a day. works fine, the carbon fiber bends a little.

Yes they fit, and they work very well. Use the medium spacers.

So what's a good fitting LIPO for the B4???? Money is no object, just want it to fit and be able to use it in the forward and back positions.

I run the Reedy 5000 in my b4 and I had to dremel some of the bottom of the shock tower in order for the strap to fit properly. Generally you don't want to run your battery in the most back position, only run it with the spacer in the back of the battery.
