The forward surface of the (instrument panel pylon?) fuselage, just aft of the engine, is all flat plate. If it were tapered so that forward surface had a smaller cross section than the instrument panel, it would put both cylinders further out into the slipstream for better cooling.Explain!
You can do away with the reflex. The Mitchell B-10 uses the 23 series foil with Junkers elevons that have a symmetrical profile. It is rigged to be at a 1 deg. negative pitch with the stick full forward. Trim tabs and/or spring trim could be used to provide neutral stick pressure at the desired trim speed. The U-2 used an inverted airfoil and twist on the Junkers. Didn't work out exactly as planned........not sure if adding junkers flaps to a plank means you can do away with reflex on the main wing.

Like with an up spring!Bear in mind I'm still not sure if adding junkers flaps to a plank means you can do away with reflex on the main wing. I think you either need to keep the reflexed trailing edge, or give the flap an inverted lift profile. Otherwise you would likely need to pull back on the stick constantly.
