Hello Powerbox folk,
During a couple of flights of my Yak 54 this weekend I've experienced two instances of unexplained roll/aileron oscillations in level flight. This is a well flown model with iGyro SRS and GPS v1. The gains have been set up and flown successfully without this effect for several years.
I confirm that the oscillations are not speed related and they have occurred once in a flight and I'm not able to deliberately reproduce them e.g. by flying at max speed into wind. Speed factor is set to 4.
I've checked the configuration and there are no unexpected settings.
Could this be a fault in the GPS unit? If I disconnect it, the iGyro reduces gains as expected.
