About this Plan

Jaeger. Radio control slope glider model.

Quote: "A Simple Quick Building Aileron/ Elevator Design For Slope Or Thermal Soaring. Jaeger by Mike Hollison.

Jaeger is a slope/thermal design for those who want a snappy looking, easy-to-build fun flier. It is also suitable for the modeler looking for his/her first aileron ship - the construction is low tech with a lot of balsa and ply; it uses two channels only (elevator and ailerons) and is a very docile performer, despite its racy lines. So, hang up your current polyhedral, rudder-elevator floater for the season and try your hand at this lean, but not so mean, flying machine!

Construction 1. Start with the wings by cutting the leading edge and lower wing spars to length and laying them on the plan. 2. Cut out all wing ribs, and epoxy ribs W-3 to W-6 in position. 3. Taper and sand the aileron spar, notch for ribs W-7 to W-10. Lay in place over the plan, glue W-10 in position and epoxy the spar between ribs W-6 and W-10. Add ribs W-7 to W-9. 4. Cut the top wing spar to length and glue in place. Add the 1/4 in balsa filler between ribs W-3 and W-4, then cement the 1/16 balsa vertical grain shear webbing between each rib, as indicated on the plan. 5. Repeat steps I through 4 for the second wing panel. 6. Next, cut wing joiner J-1 from 1/4 in ply and epoxy to the center section of one wing panel between the top and bottom spars. 7. Cut two .1-2 wing joiners from 1/16 ply and epoxy the front joiner between W-3 and the center section. Add a piece of 1/4 in balsa filler between rib W-3 and J-1.

8. Now, join the two wing panels together and epoxy the rear joiner (J-2) in position, making sure that there are 2 in of dihedral at each wingtip under ribs W-10. Add ribs W-1 and W-2. 9. Cut the bottom wing sheeting from 1/16 light balsa and cement to the bottom of each wing panel, remembering to shim up the trailing edge of W-10 by 1/4 in to provide wash-out at the tips. Add the rear 1/16 balsa strip spacers between each rib immediately behind the aileron torque rod position, and the scrap-tapered balsa on either side of ribs W-1 for the wing mount-ing bolt. 10. Slot the top of the aileron spar as indicated for the Kraft 'live' hinges and epoxy in place. 11. Next, cut the 22-1/4 long aileron torque rods from 3/32" dia. piano wire..."
