Building Instruction

1. Fuselage

Fix both halves of the plan onto your building jig.

The plan sticks together on the markings on both halves.

Cover the plan with clear plastic sheeting.

Take both halves of the backbone chain and fix it on the plan with pins.

Do not break out the temporary fillings in the backbone chain before you have finished the first

halve of the fuselage!

Then start gluing the frame halves 1-13 onto the backbone chain.

Do not put any glue onto the pivot of the frames for the excess glue will close the slot in backbone

chain and you will not be able to put the 2nd frame halve from the opposite site into the same slot.

Put glue later on onto the second frame halves!

Put the wheel bearing between the frames 7, 7a and 7b.

All stringers have to be pre bend over steam of cooking water, especially those that have to be bent

very tight!

All stringers that have to be extended must be shafted!

Glue in place the stringers G1-G5, 6x6mm pinewood,

Glue the rib 5 onto the frames 7, 7a and 8

The plan sticks together on the markings on both halves. Cover the plan with clear plastic sheeting. Take both halves of the backbone chain and fix it on the plan with pins.
Page 2 Match and glue all those diagonals between the frames 8-12 After this, match and glue the diagonals D2 between frame 3 and 4 and D3 between frame 3 and 9 Match and glue the fillings F1 between frames 6 to 9 above the stringer G4 back to the stringer G5 Match and glue the lower fillings F2 between stringer G3 and the fuselage bottom.
Page 3 When dry, match and glue in place the canopy hinge on the right hand side of the fuselage showing in flight direction! Take care to glue the hinges in that direction that you have to push the canopy onto the fuselage from the rear end side and not from the front end side! Then glue the canopy in place but trim it before for perfect fit.
Page 4 Page 3 Glue the leading edge 12 and the elevator tips in place and, after drying, sand the elevator smooth! For mounting the elevator to the fuselage, screw the 30x4mm screw into the slot of rib 1 a. The gap between planking and the head of this screw should be around 12mm but you will get the right gap when you push the elevator back into part 23 of the elevator saddle.
Page 5 Glue reinforcement 36 in place. Glue the wing joiner outer fibreglass tubing after sanding the points of gluing in place using Epoxy resin and now the vacant spar webbing between ribs 1-4. Glue spar H3 to the airbrake section. Shaft the upper planking now and glue in place as in one piece. Watch the plan for shafting! The planking in the aerial of the airbrakes will be added later on after the airbrakes are glued in place.
Page 6 Glue the fibreglass steering arms LK9/LK10 together with the 5mm spacer and along with the 3mm shaft into the housing with Epoxy resin. Then attach the airbrakes to the steering arms using the 2mm plastic tubing as an axle. Push the 5mm spacer onto the axle and glue the cover LK4 to close the housing now. Cut off the ribs 9-12 as shown that the airbrake housing will fit into that slot then.
