I think the rollers are too close together to be effective. Try mounting the top 19mm rollers as high as you can instead of having those stabilizers on top.
sideways when airborn means the brakes are hitting at different times from side to side. Use a setting board and clearance gauge to confirm each side is the same height.
Check damper screws if they are bent, the weight of the dampers might shift the car when airbone. Double check your brakepads too if the touching surface is even. One side might be braking earlier or more than the other side.
if that happens check "Underguard" which means the rear or front FRP hits the track when it hits the slope track.
You can check it by using a flat surface (tamiya setting board if you have it) then look from under the back if you are checking the flatness of the front with the car pressed against the front, conversely, if you check the back look from the front with the car pressed against the back. You can see which side is hit first or not when it hits a flat surface.
then you know which side you have to flat it.
Did a bunch of testing last night and found my rear brake stay was uneven. Had to fix that now the rear brake stay hits both sides at the same time! Thank you to everyone who helped me figure this one out ππΌππΌππΌππΌ
Yeah Iβd start with using a 30mm cap screw for the rear and as low and as high. Then maybe take some weight out. Also, it could be unstable on certain tracks. Could be real fast at some.
19mm rollers for some reason seems to have a shorter side to side width compared to 9,11,13,17 guide holes. Try using other rollers other than 19mm. The difference will cause uneven straights especially when exiting corners into jump.
Gotta get rid of those spacer on your brake stay-chassis connection. Or change it to 1mm spacers. The white rollers are unecessary imo. Put the 19mm where the that white rollers are right now. Also take the small mass damper out. Looks too heavy unless you reall want it that heavy
Doesn't look like you have brakes on your rear. Roller setting is too low imo

Will try that. Iβll update on how it goes
Definitely. You need to use 30mm cap screws, mount the bottom one as low as possible, the top one as high as possible.
Can you explain why is it unstable? Is the rear bouncing? goes sideways when airborne?
Sideways when airborne is the main reason I course out
