I like the 3010 very much. I use them in my larger planes and have not had one fail. I have a FOX .74 Eagle IV (great engine!) in the Revolver 70 so I decided to go with a stronger servo. Therefore I used the 3010 servos. I also use 148's and 3004's. Those are also good servos for 40 and some 60 size planes. My 148's are 20+ years old so I mainly use them on throttles now but again, have never had one fail.
