This castor gauge is used to measure the caster on an Mi8 when using the twin adjustable upper arms.
Used in conjunction with a set up system such as Arrowmax, SKY RC, Hudy etc.
Suitable for both standard plastic or alloy hub carriers.
When using the later AM174040A – Set-Up System-1/10 Touring cars-With Bag (2022) the castor pointer requires a little modification to fit.
