servos questions

[jimg1043]

Hi i have the hitec mgs for my lepton heli ex and i bought the c-disk style servo horns but i notcied that they are to big whats the tip to get these to fit on the servos i have?.These are the futaba c-disk servo horns rounded.

are you saying that you want to fit the Futaba horns on hitec servos?

they have different spline patterns and are not interchangable.

Actually you can use them I did.
I know this sounds mickey mouse but take a piece of the plastic bag that the parts come in and cut out a circle. Place this on the servo output shaft then press on the futaba wheel like a shim. Trust me it works and I have been doing that for years when I need to use a futaba wheels on a Hitech servos.

Check that you can turn the wheel and it is not slipping on the splines.

Thanks bob i Will try your suggestion and see if this will work for me i was getting concerned these futaba c-disk wheels are nice and very pricey and i would like to use them on my heli i will try this and post my results i hope this will help others if they run into this issue.

Yea give it a try. It's what I had to do as I too like using those wheels so I can get 90 on the servo without having to use subtrims.

It's workin for me and has in the past as well. I know it sounds a little mickey mouse and a funky "fix" but it does work.

I tried your idea and it did not seem to work very well what type of plastic did you use finless?.Was there any adhesive added to the servo horns could you give me a better tip.My servos are slipping not good except for the tail im running s9250 futaba servo so if you could help thanks.

So you cut a little circle of the thick plastic bag that the parts came in and the circle is big enough to fold over the output shaft when you press on the wheel?

You are basically shimming the smaller output shaft splines to the splines inside the wheel. Dont forget to put the screw in before testing for slippage.

This has worked for me for years so I know it works. Other guys I know have applied a thin heat shrink to the output shaft then trimmed it so it just bearly stuck up above the shaft then pressed on the wheels.

If you cant get it to work then your going to have to go buy the Hiteh heavy duty servo arms but keep trying as it will work.

Maybe the heat shrink will work better i will try that see how it will work.
I know this is off topic but what is your gain setting on your radio for your gyro i am using a futaba gy401 and my setting on my optic 6 radio is like 25% does that sound right?Let me know im still new at this heli thanks for quike reply

[Finless]

My gain is 38% on my Futaba 14MZ. I dont know how to convert that on a OPtec 6 but I beleive they operate similar as far as gain percent.
