Default PT Gyro Servo Size

The Flyingbalsa website recommends Hitec HS81MG for the PT Gyro Kits. Is it for the small one or PT 25 or both?

I never used the HS-81 on anything bigger then a .15 size gyro.

Hi Wahid,

We recommended the HS81MG for the 1/2a PT Gyro.
For the PT Profile and the PT25, we recommend the HS225MG or equivalent.

Do you have any experiences without metal gears? I thinking about the new JR's Digital DS821 which has resin gears for $30.00.

Nylon gears will work fine as far as flight loads.
They will strip when you have a few tip overs or ground strikes with the main rotor.

I do not have any experience with the JR composite gears.
Hitec advertises their "Karbonite" composite gearsets as "four times stronger than nylon".

Hope this helps,
John
