Yes, it’s pretty much all wood. Which is different than the Tailwind I’m working on now. The plans call for 65-105 hp, and I know where I can find a conical mount Lycoming O-235 to use, that’s from a Piper Colt...
My plans show cables only for the rudder, all other controllers are push-rods.
The Tailwind also uses push-tubes, but the flap and ailerons are on concentric torque tubes for the surface leading edge, so they ride in concentric bearings that bolt into the rear of the wooden wing. This is because the Tailwind wing is pretty much an enclosed structure.
The Titch plans shows a cross tube that actuates the flaps that are hinged with piano hinges on the bottom. The ailerons use a piano hinge on the top that has enough clearance for the downward deflection. The push-tubes act through a set of bell cranks, which produce the differential deflection of 25 degrees up and 10 degrees down called for by the specifications.
Terry recommended that I build the fuselage with the 2” wider option.
