We actually replaced the roll servo about 10 hours ago. I have tried making a full series of small adjustments in each of the four parameters including gain, sensitivity, max bank, etc. The only notable thing is that with the sensitivity below 24 (max allowed is 24) the problem gets noticeably worse - same slow, continuous 16 second cycle side-to-side-to return, 2-3 degrees bank each direction. It improves markedly as the sensitivity is increased. It's like if the sensitivity setting could go to about 30 the problem would be solved. Flew to Montana two days ago, 3.5 hours each way, and slow rock & roll both ways. I was solo (social distancing?) so nobody along to get sick. I love the Skyview system otherwise, and especially compared to another system I often fly (new Bell 505) by another manufacturer...
