Pivot Ball vs Steering Block (Team Associated vs ARRMA)

Published 2022-11-04
When the pivot ball steering assembly turns, the entire steering block is tilted because of its fixed caster and because of this, The camber will either be thrown negative or positive depending if it is steering left or right.

With the original steering block design, there is a two piece design instead of one block on pivot balls., these two units are “caster block” and “steering block”.. like on the Team Associated, the caster block determines the caster angle and also holds the
“steering block” which turns separately from the caster block. This helps with keeping the caster unchanging while barely affecting the camber.

This is why the Team A. has a better contact patch while steering than the ARRMA felony has while steering.

As far as pros and cons when hard stopping and hard acceleration affects both mechanisms, that’s another topic.

    I think the biggest reason for changing the design is for manufacturing purposes and costs… The pivot ball steering block design has less moving parts and is more robust and reliable and easy to maintenance. It’s also cheaper to stock spare parts vs multiple smaller parts that MAY or MAY NOT be frequently purchased by consumers and possibly complaints from consumers about practical prices. These days ppl like brute power and brute force so a more robust design was inevitable. ENJOY THE VIDEO😆

    I can see what you mean know about the pivot ball vs steering block, they may be doing that for performance though? These buggies lean when coming into, are in, or coming out of corners, it seems they would benefit from camber while turning Not really 100% sure. Another thing to consider is the fact during corners your rear tires do more of the work than the front/ running on a dirt track you would also lack traction and so less roll, meaning less contact patch? Not sure, some slo-mo comparisons between some different cars would be neat to see Team Associated isn't very competitive in 8th scale from the looks of it (if you look at their recent 8th scale buggy chassis, people tend to not like the handling characteristics) and for that reason tend to not be running them, instead at my track i see a lot of 8th scale kyosho and tekno I've been tracking mine last 2 days, have already sourced down spare parts cars. I'm going to be tracking/keeping this thing as long as i can. really fun car. The durability is amazing, sadly i don't think i can actually drive and record at the track, so i have no footage for now. If and when i run out of parts to keep running, ill be keeping the car around for memories and going with kyosho or tekno. I will say this car looks amazing on the track, all you see running is very modern looking buggies, it's a nice change of pace, i appreciate really anyone putting work into keeping old cars working so thanks for keeping yours in running shape
