I have been using Hitec servos for years also. From Giant scale warbirds to Turbines and have not one failure to date. These are big heavy planes that are much more demanding than a 18 to 25 lb jet. Ziroli Hellcat, P-47, P-38 AD F-16 Avons F-15 and a Viper Jet. My latest project is a Cactus Aviation Tigercat with a pair of Brison 5.8's. The Tiger is huge has 80# of thrust and is heavy, I'm not sure if you can push a servo much harder than that. Not one problem! Good luck deciding Mike
