Hi Dan! Definitely would like to see the video. If that's an active link at the bottom, I couldn't get it to come up. I agree the flaperons/elevons do appear, on the 1:1, to be coupled, albeit, doesn't appear to be much movement on the flaperons. Honestly, I like your hinging solution better. The wiper is problematic, but I will probably try some 1/64th ply before abandoning the bottom hinges-the lithoplate is too stiff. In terms of the pressure exerted, I don't know which method is stronger. I haven't made much progress on mine lately, frankly, trying to finish up some other planes on the bench. As cold weather moves in here, I need every inch of space to work on the Su. Since my wings are built up, my servos will have to be placed in the fuselage area. In watching the Ram-K DVD of the full size, it appears the LE flaps are down throughout all the acrobatic maneuvers shown. I'm assuming, therefore, the LEF's come up only at flat out, level flight. I'm not sure what size servos are needed, however, when they're 'extended'-or deflected- they should be at the servo's max position and not really 'holding' anything. Bill
