All depends on the track and your handling. Kit setup is 2 spacers rear and 3 front.

Default A tower or C tower-difference?

I purchased a used 4.2 from one of the members here and notice it has the C rear hub tower with an unshaved chassis brace with no washer. From what I can tell this is a high grip setup. Our outdoor track is medium grip and goes down from there.

Would I benefit from ordering and changing back to an A tower?

Thanks

I would imagine, that would be way better than the C hubs!
The C hubs were used with a shaved u-brace to free up the rear end if I remember right?

For any of those interested that still have a B4.2 I have a spare parts car with a couple of chassis and a custom body. Would be willing to trade for a servo.

Try the c hub and shaved brace. I liked it on a low to medium bite track better than the a hub.

Default Antenna Question

I got a plastic replacement antenna for my b4.2. This thing is 12" long!
It looks like there are a few extra inches coiled up in the receiver box.
How long should I make mine?

Which radio system do you have?

If you are asking about cutting the receiver wire, in general it shouldn't be cut. In the cases where it can be it is important to cut it to a specific length. The length is part of the tuning to the wavelengths it is receiving.

If you are asking about how tall the antenna should be, if it's a 2.4GHz radio you have lots of options. Many don't run a antenna tube at all, just leave the wire on the chassis, some run a short (say 3~4") tube, some run the full tube. If not a 2.4GHz deal probably best to run the full or nearly full height.

I'm switching this up to mod and using the avid setup, thoughts on gearing my 8.5? I think I only have the 81t spur or the smaller 72t. Thoughts?


momo
Yep, shaved level. My home track as well ... :-)

Getting my B4.2 dialed in but I stripped out the stock servo horn. Can I get some suggestions on which aluminum horn to use? Thanks.

Losi 22 series fits fine . or just replace the plastic one , would rather blow a horn than a $100+ servo.
