servo size?
 

Hi! Noob here with a question. I'd go by the field and ask but the weather is yuck today.

I just purchased my first plane. 60 size trainer. I have several used Hitec HS 55 servos.

Are these to light a servo for a 60 size power plane?

I'm thinking they would work for the throttle but am unsure of the control surfaces.

Thanks,
Bob</p>

Those are too light for the control surfaces. Any good standard servo will work fine.

YES, those are too small for a .60 plane, they are designed for park flyers and 1/2A scale. Use any standard size such as the Hitec HS-311

Or my personal favorites are the Futaba S3003

Thanks guys that is what I thought. I'll get some of the standard sized ones and save these little ones for something else.

I concur with the fellows the HS 55 will not work well at all and soon be stripped. However you do not need to use a standard size servo.

For all my throttles what would be called twentyfive size and up I use HS-81, HS-85 (this ones a favorite) and on some very large stuff I use HS-225 (This one is in fact a favorite in some other locations also).

So you think the 55 would be too small for the throttle too? It's not like a standard servo is expensive or anything but I was just hoping to use what I already had. I guess to be safe I can go bigger for everthing and call it a day.

Yes Bob they are, those tiny plastic gears are not intended to stand up to the vibrations in a glow powered airplane expecially tied to the throttle. Where they tend to fail in this application is from hard landings. Seems strange but these tend to strip those gears.

I understand the desire to use what you have but better using a little will power and get something more appropriate. Agine you certainly do not need to use a full standard size servo though on the throttles.

The advantages go beyond just lighter weight. It is particularly nice in a tight compartment to use a servo that physically is a little smaller. I have not used a 'standard' servos for throttle in many years.

Do not discount the HS -225 called the mighty mini, throttle dutys are a piece of cake for this one and I also use it for example on dual ailerons servo setups for a lot of airplanes up to what would be called sixty sized. heck even use that one for ailerons on many of my multe engine ships.

OK thanks I'll give up on that thought.
