Dee ordinary people just like you & I fly the Dash day in day out. I doubt it's a type that's too difficult to master, 9 switches or not!
Besides it's a prop plane with the wing on top, couldn't get more basic than that.
Dee sounds like the Dash was also designed by those that made the Dehav planes. I used to fly an old DH104 (Dove) where you where lucky to have 9 switches all in the one spot !
