Servo Replacement

Our team is currently using a hitech 485 servo to “launch” the boulder into our shooter.

Unfortunately we keep breaking the plastic shaft on the servo, we are looking at mounting it differently to prevent hit on the assy. I am also looking for alternative to that servo…

Is there any alternative to hitech servo? Something strong with steel component that are allowed in the game ?

Any input would be appreciated !

There are a number of Hitec servos (and other brands) available with metal gears and output shafts.
