T-34B Mentor (oz16125)

About this Plan

T-34B Mentor. Radio control scale model. Wingspan 70 in.

Note the Beechcraft T-34 Mentor (oz7726) was first published in February 1968, AAM. This here is plan from the later SIG kit.

Quote: "NEW INSTRUCTIONS FOR BUILDING T-34. REPLACES INSTRUCTIONS SHOWN ON PLANS: The Sig T-34 is of straight-forward and simple construction compared to many scale airplanes. In the following instructions I will attempt to help you over the more complex building methods. I am sure there are many other ways to accomplish some of the building problems, but if you follow these instructions you will have a sturdy well built T-34.

FUSELAGE CONSTRUCTION:
Lay out both fuselage sides on a flat table. Remember there is a right and a left side. First, glue 1/16 plywood doubler with Sig Epoxy or Sig Bond. The plywood doubler is 1/4 shorter at the nose to allow for the 1/4 firewall which butts against the 1/16 doubler. Add 1/4 sheet wing mount doubler. When fues, sides are dry, trim doubler with a sanding block. Now be sure and cut in stab. incidence shown on plan. Pin fues. sides upside down on your building table with the leading edge forward protruding over table so you can install F1 and F2 using side of the table as leveler for F2; glue in place using Sig Epoxy for fuel proofing. Glue F3A in place; add 3/8 nose doublers. Pull rear of fuselage together adding 1/4 sq cross braces. Add 3/16 center rail to fues. bottom and plank bottom of fuselage. This will hold fuselage rigid while working on top of it. Do not add block forward of wing, as you will need fuselage bottom open to install nose gear mount later.

Remove fuselage from table and glue in upper deck bulk-heads, plank top deck back to F7. Roughly sand planking and sides and arounicorners at bottom of fuselage. Next install nose gear block, drill holes for motor mounts and install blind nuts. Drill hole for tank outlets. It's a good idea to dope or epoxy tank compartment. Next install bottom block and when dry sand to shape. Now is a good time to cut canopy to shape and fit to fuselage. Trim planking with about 1/4 of canopy overlaping planking. Don't install canopy until fuselage is completely finished and painted. Next install cowling mounting block, mount your cowl and sand fuselage to fit, using cowl-ing as a pattern. At this pont lay fuselage aside as tail assembly must be completed before finishing it.

TAIL ASSEMBLY CONSTRUCTION: Start with stab by building 1/4 x 1/2 frame over 1/16 sheet; when dry in-stall top sheeting. Use lots of pins to hold stab down so as not to warp. Sand elevator to shape and install elevator horn with epoxy; sand stab to shape, now install hinges. Elevator and stab should be finished and ready for doping before installing on fuselage. Build up and install elevator torque rod with servo end long enough to install later. Slide torque rod in rear of fuselage and glue stab in place, checking alignment. While drying, rudder and fin may be built up the same as stab and elevator.

Install rudder to fin with 3/32 wire going through stab as per plans. Cut rudder horn fairing out and silver sol-der horn in place. Glue fin in place, also balsa fairing block. In-stall rudder torque rod and glue on rudder horn fairing. Be sure and hollow out tail cone block for elevator horn and install block and sand to shape. Now shape, sand, and glue dorsil fin in place, checking alignment. Wing mounting blocks, instrument panels, and cockpit floor may be installed now..."
