Thanks all of you for good input, I´m still not sure which way to go but will now take a week off, leave the snow and cold wind in Sweden and go the Canary Island for a week. Will take Andy Lennons book with me and think a bit more before proceeding (thanks for the tip MikeJ)
Nate, yes maybe putting flaps on both surfaces is the easiest way out and in fact that is what Andy Lennon did on his Swan canard featured in Model Builder Oct.-83 where he states:.."...adjust the flap deflection so that when the foreplane flap is at 20deg, the aft flap is at 30 to 35deg deflection........surprisingly, deploying the flaps had no effect on longitudinal trim, the model seems to levitate as it slows down..."
The reason I thought about a third "middle flap surface" instead is special and I will try to explain later.

Johng, yes, low pitch props is an alternative but will detract from normal flying performance so it has a price of course. Must live up to Revver Brother expectations..

Allan, go get yourself a digi camera and show us more details on the Ferret...!..and put the new version of it at the very top of your list...pliiiis..!

....must go pack the trunk now.....again thanks all of and keep the good stuff flowing do not get distracted by me catching the sun..........Cheers/Harald
