JR, Futaba, Airtronics, and HiTec have had their problems. WreckRman2 can't prove that he lost his airplane because of any servo. However, he is the most vocal of the few people expressing their dislike for HiTec. If you look around you will easily find someone who will knock every product known to man on this board. Take everything both bad and good with a grain of salt.

I currently run all digital HS-5645MG servos in my DP Extra 330L, and run all HiTec analog servos in several other airplanes. I've read the threads about HiTec servos along with problems and complaints about the other manufacturers products. I worry (NOT) about it so much that I just purchased six digital HS-5945MG servos, two digital HS-5735 servos, and one HS-225MG servo for my 35% Carden Edge 540 that is on the bench being built. In other words I don't worry any more about HiTec products than the Futaba PCM receiver that will go in the plane. Plus you simply CAN NOT BEAT THE PROGRAMMER FOR MATCHING UP THE SERVOS!!! It is a great tool the JR and Futaba are way behind on. Both have come out with their little match type boxes that go flying with the airplane. It looks like you will need a few of them for each airplane using multiple servos per control surface. Plus it is like you mentioned, it is just something else that can take a dump. I want to keep the chances of product failure low.

It is just like everything else, test the snot out of everything in the plane as often as you can to minimize the risk of failure.
