Yikes I better look into that I even have them on my 1/3 scale Cubs and have had for yrs..According to everything I read they wear 4 times longer but I havent read anything on them for some time now...I have never had one fail but a big Cub is pretty easy on them usually. I have 645 MG's on my 1/5 scale cub and they work great. They are just noisy..The gears are not quite the same stuff as the gears in a diff or a tranny though..If they were they would never wear out..Thanks for the heads up..I am going to do some research on this...
A cub and somethng like an Extra are a bit different so I wouldn't give it too much thought. Only way I knew about the brittle gear train was someone on RCU mentioned it. I then sent off an email to Hitec and got a good reply. When I bought mine th4y were advertised as the wave fo the future and nothing was mentioned about gassers, vibration or surface size of controls. I still don't see it mentioned"?
I have had a number of high end JR servos with Nyon gears and I felt they works every way as well and any other gear set. etel is not a must have but on big planes I like them. As soon as I see any slop I open them up and check the train out.
When I'm looking for new servos I always go to servo City to get the specs and info. At the time they may not be where I get the best deal though. I do shop around.
When I posted this I just figured there may be something on sale people could use and save a few bucks.
Servo selection is like anything, it's up to you to pick out what will work best on your new bird. I tend to mix and match as I see fit.
