I too have a soft spot for biplanes. They do fly a bit different but not overly so. As far as the Phaeton is concerned, if you can handle other sport aerobatic airplanes you will be fine. I can't agree with the statement that they need to be flown 100% of the time because that implies less stability. That is a setup/trimming flaw that could apply to any airplane. Speaking of set up, one of my pet peeves is the way most ARF bilplanes set up the ailerons on a 4 aileron biplane. What I see far to often is the lower ailerons driving the upper. I don't have an issue with that method although I do prefer 4 separate servos. However what I see if the hardware to link the airlerons together is all wrong. Most of them have the link pivots on the upper wing below the hinge point and above the hinge point on the lower wing. This will result in a differential throw between the upper and lower ailerons. Not a good thing. Sig sells hardware that will bring the pivots onto the surface center line where is should be. This way you are able to get all 4 ailerons to have the exact same throw. Then by using the dual aileron mix in your TX you can dial in the correct amount of aileron differential to eliminate adverse yaw and a roll to pitch couple that would happen without the differential.
