Soft linkage
Here's what I did on my Jett FIRE 50 powered Dust:
Take about a 2 inch piece of the INNER part of a nyrod. Thread some fully threaded pushrod into both ends, cut to proper length for your setup. Use nylon clevises on both ends. This will isolate the servo from vibration.
I must have close to 200 flights on my Dust and the cheap FMA mini servo I use on throttle still works perfectly! I am using the same setup on my Whiplash.
