Some comments and explanations.

The two piece wing was accomplished with the use of phenolic tubes and aluminum tube inserts AND an aluminum C channel with an aluminum tongue insert wing joiner. Both are supplied by Sig Mfg. as replacement parts for their Something Extra and J-3 1/5th Piper Cub kits. The C channel wing joiner for their Spacewalker. I choose to make 1/8" ply ribs for those ribs where the phenolic tube and wing channel would be built in for added strength when epoxied in.

The polyhedral wing. The Senior Telemaster as designed is to be built as a one piece wing with about 3" of dihedral under each wing half which are joined by epoxied in dihedral braces. My shop is in my basement and I have either a PT Cruiser or a Ford Ranger PU for transportation. I either came up with a two piece wing design or had to forget it. I've built gliders with polyhedral wings (flat center sections joined with the outboard sections having dihedral). This what I choose to build. I used the supplied dihedral gauges and duplicated them to join the two outboard wind sections to the flat (when joined center sections). I also incorporated flaps for the two center sections and have added ailerons on the two outboard sections. 1 flap servo and torgue rod and 1 outboard aileron servo will be mounted in each wing half. ( 4 standard BB wing servos). 1/8" ply rib formers were also substituted for the as supplied balsa ones at the wing joints for strength and nos. 2,3,4 & 5 positions (all those which hold the wing tubes). Also likewise at the polyhedral joints. The wings were built on two long 1/4 " dowel sections and pre-drilled for the outboard aileron servo leads. As a building aid suggestion........build the wing in two 48 inch long sections. The plan being to cut each into 24 inch long quarters. One 48 incher to be the flat center sections housing the wing joiners and the other to become the 24 inch long dihedral sections. This technique helps greatly with keeping all sections flat and true on the building board until being cut for joining.

Fuselage mods. I had my reservations about trying to mount a bolt down wing on the substructure cabin area as it is designed and chose to beef things up quite a bit. First, I replaced the No.2 1/4" balsa former with a ply duplicate. I also designed a 1/8" ply web structure to laminate inside the entire cabin bay area balsa structure and reinforced the no.3 and 4 formers as well. I then built a servo/receiver bay aft of #3 and between #4 formers with a hatch to access. Rails will be installed to mount the pull-pull rudder/tailwheel and elevator controls.

The rudder will be essentially doubled in surface area via width wise extension.
