Tailsprings, Brakes, Pitot, Throttle

Build Hours: 997
Vacations and summer lethargy has slowed the progress. We have been finishing some of the details that are not covered in the plans. When the throttle and choke assemblies are routed into the engine compartment and the pitot is installed we will be back to the outboard wing sections.

This is a 3/16" plywood seatpan that keeps the spar from digging into the back of the legs.

We modified screen door springs from the Lowes Aircraft Dept. for the tailwheel springs. The springs allow some give if you touchdown with rudder input and with the springs in compression there is less chance of breakage.





This blurry little bracket was riveted in the rib corner of the 3 inner ribs to hold the brake cables in place. It would have been much easier to do this before skinning the wing:)

Example of the brake cable bracket installed. The pitot and static lines will be tie wrapped to the brake cable.

Brake cable entering wing.

This is the right brake.


...and the left brake.


This floor pan allows your feet to rest without sliding to the fuselage center bottom. The heel brakes seem to work well.


This is the parking brake assembly. Rotating clockwise approx. 8 turns will lock the brakes. A doubler was added to help the bulkhead take the brake cable loads.


This is the pitot-static tubes. Spruce sells a similiar setup but we had some 1/4" tube and a lathe sitting idle so...




The throttle and choke control is still a work in progress.

Wing Center Trims

Build Hours: 917

The trims are a real challenge. We can't decide if we should admire Morry (the designer) or shoot Morry for creating these nice fairings. They are a real metal working challenge and we are still working on the front trim.

Plan Note: The plans indicate 6061-T6 for all of the trims. The front trim requires too much stretching to made from 6061-T6 IMHO. My hat is off to you if you made your trim from 6061!. We are trying 6063-T52 from Lowe's right now and Rick has had some success wrestling it into shape. We may have to back down to 5052-T4 or 3003 from Spruce/Wicks before the trim is completed.
