E-Flight S75 servoes versus Hitec HS55 servoes
I stoped at my LHS to buy three Hitec HS55 servoes for my AXE, found that he had only two in stock. He then told me that I might look at the E-Flight S75 servoes. Here is what I found. The size and mounting holes were the same. The stock arms can be used as thay fit with no mods. Now for the specs. Torque Hitec HS55 .15 oz. E-Flight S75 .17.2 . Speed Hitec HS55 .17sec E-Flight .12 sec. Weight Hitec HS 55 .28 oz. E- Flight .26 oz. Cost Hitec HS55 18.49 ea. E-Flight 14.99 ea. Hitec HS55 $ 55.47 for three. E-Flight S75 $ 44.97 for three. Now for the bad news. TheE-Flight servoes run backwards from the Hitec servoes. I reversed two of the servoes so thay would go in the right direction, and mounted the front servo on the right side of the frame . It worked great. The heli does fly better now. If you deside to go with E-Flight servoes I can tell you how to reverse them.
