wondering what size of nut the plastic shock nuts are, im looking to replace them with metal locking nuts, i remove my shocks often and these nylon nuts are wearing out too quick for my liking. already did the front wheels since im racing indoor clay my tires are removed easily 6-10 times while at the track alone, then if i go for practice, double that lol

re: the pin falling out.

you mean the pin under the c clip? if so put the c clip offset like the manual says then put a drop of CA on the clip away from the pin. that keeps the clip from rotating and allowing the pin to fall out

rear wheel nuts are 8-32, uses 11/32 socket.
Shock mount nuts are 5-40, using 1/4 socket. 4-40 would be 3/16. if i've not lost my mind.
you can salvage a nut in the short term by running it on backwards.
all of these are available at your local hardware store in various materials (alum/stainless steel/steel/etc) if your LHS can't get them.

cvd pins fall out because the set screw backs out. your options are grind a small flat spot on the pin. use minimal mount of loc-tite on set screw. cvd rings (press on) or heat shrink.

shock mount nuts are 4-40...the only 5-40 nuts on a b4/t4 are the front axles and slipper nut. both would use a 1/4 inch driver. the smaller 4-40 nuts use a 3/16 driver.

Hey guys,
I just purchased a b4 here on rctech. I am new to 1/10 scale and had a few questions about my buggy.

1. Is it a FT? I want to download the instruction manual.

2. What size pinions do I need to have on hand for a small indoor track. I'm not sure the size of the spur gear...

3. I'm having difficulties installing the servo..see pic. The mounting holes are too far from the arms attached to the servo.



4. What is a good range of shock oils to have on hand?

5. Should I go through the diff? It seems to be very smooth. Is it oil filled or greased? What do I need to have when it comes time to rebuild it?

Here are some pics of what I've got so far.Thanks for any help!!

tom2one looks like your servo will need some shims like these


I recently got my b4 and just went ahead and bought the Bfast diff with the greases.

Yes this is a FT.

It depends on what size motor you plan to run. A 10.5 would be good. If you run a 10.5 your gearing would be about 78/25 or 81/26 or 84/27.

3. I'm having difficulties installing the servo..see pic. The mounting holes are too far from the arms attached to the servo.
Its hard to tell. You may need a different servo, I doubt it though. Don't tighten everything at first. Get the blue mount on the servo loosely to see where things are lining up.

4. What is a good range of shock oils to have on hand?
I would get 35, 30, and 25. I use 30 all over my self, but get the other two as tuning options.

5. Should I go through the diff? It seems to be very smooth. Is it oil filled or greased? What do I need to have when it comes time to rebuild it?
Honestly, I would rebuild everything. The diff is a ball diff and you should consider picking up a couple diff rebuild kits as this is a really important part of the car.

Ok so I picked up a set of used FT B4 shocks, I pulled them apart and they have pink 3 hole pistons in them. I know this is a long shot but any ideas what they could be and what # ae piston could they be equivilent to?

Cameron Kellogg

It's a Losi #56 piston.

would that be close to an ae #2 ?

There is a chart somewhere (can't find it right now) about the difference in the pistons and the pack effect they have. The Losi piston was something that some people were trying. I think the current Cav. set-up use #2 pistons to start with. Just depends on your driving and track.
