I’ve a yellow aircraft F15, similar size to the legendary avonds F15
I previously flew the model with an iGyro SRS, with the older software where you adjusted all three axis during one setup flight. The iGyro made the plane feel great.
I’ve since changed a lot of other components, (new engine, pipe, electron retracts) but I added a mercury SRS.
The CG was checked on xicoy scales and it may be slightly further back, but not more than a cm.
I’m surprised that the model feels so different. There’s a terrible wing rock. Setting the gain to 83 percent didn’t help. Setting it to 100 percent helped slightly more, but it’s not perfect.
I even landed, and set a slider to allow me to adjust rudder gain independent of aileron and elevator. I was concerned it may be Dutch roll, and didn’t want the aileron and elevator gyro action to mask it.
So the question, should a plane flown with an iGyro SRS behave the same as when flown with a mercury? My thoughts were that it should.
If so, I’m confused what could be making such a difference.
