Having tested countless designs to achieve the lightest and strongest possible construction, this is my final build.
It was designed as a complete project incorporating motor and servo mountings, push rods and control horn locations, with interchangeable engine cowling at the firewall. All control surfaces, rudder and elevators are pre-slotted for hinge insertions and can be glued in place with super glue.
The air craft is a typical high wing Clark Y-wing section with good dihedral and lots of wing area. This is an easy-to-fly trainer model, not representing any scale design of any kind. It is a popular design for anybody starting out, irrespective that it is a 3d printing exercise in RC modeling.
The whole plane is constructed in modules no larger than your Makerbot-type 3d printer. The proto type here in the pictures was created on so most printers with a compatible print area will suffice.
