tryed putting a small gyro on a old pt 40 to see what it might do(going to try it on my frist twin) well i set at about 30% start the roll out and really didnt see a big diff, i did try at over 30% but got alot of tail wag.? if any one knows, it is that the rudder is to small to make any diff,,,,,,or what...thanks for any help

Handyman,

I'm not sure what your trying to actually accomplish here, but your tail wag is from a high gain setting on your gyro. I speak from the perspective of a guy who flies heli's. When my tail "wag" was excessive, I turn the gain down on my gyro. Another issue you might be experiencing it the slow speed of your servo. Normally gyro servos are high speed digital to allow for the constant commands from the gyro.

I looked at my heli gyro settings. I run mine at 50% with no noticeable wag in the tail. In my opinion, it sounds like your servo might be too slow. What servo are you using on the rudder? What Gyro? Can you control the gain from your radio?

I'm not very familiar with the PT-40, but isnt that a small rudder trainer?

Mike

yes it is a small trainer with a some what small tail, iam useing a reg servo not high speed, i can not control it from the radio, its a single type gyro.........
