i have yet to have any issues with my servos, I have been using the mounts like they are, with the fingers to help hold the servo solid so it doesnt move. I have solid mounted my servos for years in all my vehicles never with a problem. I do however run heli servos in 1/8 cause they are built to handle high amounts of vibration that Heli's cause. I am using the JR DS8911HV and DS8917HV. Neither heat nor vibration have been an issue in my Serpent, and I have raced when it was over 100 degrees, and with an engine reaching 250 degrees. Also no problems with the throttle servo horn stripping, but I am anal about getting my linkage and end points perfect, and keeping it all smooth and bind free
