I used a drop of glue, so if im in a big crash it might break loose, when you are running no servo saver it is huge to make sure your end points are dead on correct, nothing will strip a servo faster. But on my track that is smaller, medium grip having it glued made it a hole new car, it turned much differently, way more steering.
Some of the guys here might know me from tq, where I had one of the first team c buggies in the us, when the big bores first came out they werent fastere, in fact in some cases the smaller shocks felt better, I guess the same could be said for springs, so even though you are seeing a lot of setup sheets with kyosho this amd losi that, chances are they are just testing and would most likely turn the same laptimes with ae springs.
I think many are looking for a comparison on the b4, b4.1 long chassis and the 22......I had a 22, and probably didnt give it its fair shake, but I felt the team setups where not there, none really worked well at my track, and being a privateer in 2wd acter years of not being, it was easier to switch, the 22 has a lot of potiential, but isnt quite suited to every track amd every driver, I would look for it to be there in some time down the road. My son has a ft b4, I put the long chassis on it to match the new setup and ot feels very good, very very close to the worlds car, the b4.1 you can buy now is as perfected as you can get, the setup out of the box is good for most drivers and tracks.
