How do you set your flaps up, switch or a dial? My 8UAF will apparently allow only 2 'down' positions on one 3 position switch, up, down, and downer! The dial would allow a more infinite selection. I see advantages to both. I'm rigging a Ziroli 'Stuka' and trying to decide which route to go. If I use a switch, what's a good degree of throw to program in for starters. Any thoughts? Bill
