Ended up turning my radio dual rates down to 70% just to keep some aspect of cornering stability.
In your opinion, for someone looking to make a change, what platform would you describe as more stable, consistent and easy to drive?
as @30tooth mention above the problem comes from the short lower arms and the long upper camber links and some solutions I found ( @30tooth correct me if I’m wrong please )
•running the camber link lowest possible on the tower ( higher roll center )
• using the camber link shortest possible on the tower. ( as mention by 30tooth)
• minimize the distance between the out drive and the outer hinge-ping on the arm vía the hub
• running the right amount of camber no too much or too little
• using the mbx7-t hinge pin which is narrower than stock combine with the mbx6r arms that are longer than the mbx7 ( car keeps having the stock track width ) part #: E0150 arms , hinge pins E2127, E2128.
• buy another car
all of those should help tame the rear a bit , also sometimes asking the pros helps , but other times it might get you more confused, not all pros know car dynamics and theory , they just do trial and error until they find “the setup” rather than go on and do what @30tooth does and apply actual theory , acknowledge and physics into these toy cars.
