I'm running 17.5 and i got rid of the on power push but in the mid corner it doesn't feel stable and pushes a little, I can't get it to stick to inside line unless I let off completely. I'd like to be able to acc sooner without pushing out.
I'm rear motor

The axles are longer and work well with all rims I have tried.

great news! thanks 67rs! now if amains could restock that would be rad.

also noticed it has chrome steel balls. did you replace with tungsten? im thinking of tungsten for main diff and thrust, possible ceramic thrusts. any suggestions for the thrusts? thanks so much.

seriously speaking..switch from tungsten to ceremic..not much diff..maybe more seasoned racers can tell the diff, for me, yes it is smoother..performance wise..i really cant tell the diff

I"ll try this first, and if it still pops out I'll try glenn's solution.

I ordered the rb5 aluminum piece before I knew it was wider, so want to get the geometry back to stock so goin back to the b-block w/brace.

i bent the exotek front brace on the first race. got tangled with another car. Wonder if a plastic piece would stay true better then aluminum. or even carbon fiber

And i think the bumper shoulda been beefier upfront, because that brace bears the brunt of my mishaps.

Here is my setup if anyone wants to try it. The car is super easy to drive and it jumps great.i liked the shorty servo the best but can use a full size servo if needed.
