You Hpasp!
You said long ago that the Dvina will be more difficult, but it's apparently not quite so difficult as I thought.
I think the Dvina easier to manage, but harder to hover!
I would say that the Dvina very easy to manage too easy and not many settings.
Volkhov much harder Dvina my opinion.
Dvina has a wide beam modes only and 110/55 km, which is much easier to Volkhov!
Great!
