I will be honest, I have been buying BB servos now for 2 years in my Parky PLanes. I own now at least 35, maybe 30 BB servos. I usually run the 371's, but I tried the 308's. I had one dead on arrival, and I got it replaced. It worked great and I sold he plane with them in it, and it still rocks on to this day. I have had 1 field failure of 30 servos. I dirtnapped my flying wing (Overlord) and it stripped it. That was Pilot Error. So, I have not had a single in flight failure and I fly 3-4 times a week with something Blue Bird. I am about to put the 621 MG's in a plane and go try them. I want to try some glow sized servos... Rock on Blue Bird... No more HS 55's for me...
