is this gyro junk for the corona or what. using a hs-81 at the tr and I've been playing with the gain. the tail is all over the place. I've checked for binding and slop everything is fine. I'm not using any revo mixing. any amount of wind at all and the tail becomes almost impossible to control. the tr moves in all the correct directions when I move the stick and when holding the heli and spinninig the nose left or right.
anyone out there been able to set the gyro up with the corona with any luck. If you have please tell me your tricks, thanks.

I tryed to use the pg-03 on both the hummingbird and the corona with absolutely no luck.It was not very user freindly.I finally got the GY-240 which I thinks works to good.It locks the tail but It don't seem to have as much flexability as I would like when trying to rotate the tail.(stiff)

I had problems with my LMH tail being hard to control and I kept tearing the system apart to see what the problem was. I finally l discovered that the black tail drive gear had the plastic slipping in teh set-screw collar! I replaced the gear, which otherwise appeared to be undamaged, and it settled down. I did have to readjust the gyro as I had been thinking that the problem was there.

In doing all of this I found that the tail rotor pitch control could sure be better. The TR didn't return to the same spot when the TX stick was moved to the left as compared to the right.

There are a lot of things I'm going to work on improving as I really like the Corona for the basic job it does so well. One of the things I'll be doing is trying out Matt's belt drive to see if that doesn't make the tail rotor drive more reliable, though since I'm getting better and not crashing so much (and as hard) the stock system is less problematic.

Are you sure the gyro is mounted in the correct orientation? Not all gyros are the same.

The GWS PG-03 is a non-heading hold gyro. So when the wind blows it will weather vane. If you want your tail to stay in one place you need to buy a gyro with a HH feature.

Take Care,

I use the GWS pg-03 on the Corona for hundreds of flights. It is rock solid and I recommend it. The best thing (vs my GY-240) is the PG-03 axis is along its side so it can be easily side mounted directly to the crutch, giving it very tight coupling and response.
