How to Support Bell Crank Shafts on Team Associated Pro4 SC10 / Rival MT10

[Lumikko]

The bell crank shafts on the Pro4 SC10 / MT10 are 5 mm plastic rods that seem to have some support at the top but the amount of flex tells otherwise. I took out a caliper and verified that the screw heads have a sloppy fit to the holes below the main chassis.

A simple and cheap fix: heat-shrink tubing to thiccen them up!

This probably doesn’t solve an actual problem but feels good to know it’s there.

Sounds solid! Do you have pictures of the brace? Did you modify something else as there seems to be little space between the bell cranks and chassis?
