Keel Stiffening Lay-ups

Once the keel is installed, you need to do series of stiffening lay-ups with Tri-axial cloth. There are four inside the keel, one runs along the floor and up onto the canard bulkhead (3 plies of 5″x18″, running 10″ onto the bulkhead), one left to right (2 plies of 10″x13″ with the 10″ side running […]

Speed Brake Cutout

The majority of the speed brake work was done during our visit to the factory’s Head Start program. After taking inventory of our parts and getting the doors and keel off of the airplane, we cut the indicated door out of the bottom center of the fuselage. As with all cut outs of this type, […]

Rear Aileron Control Bracket

In this section we mounted the front aileron control torque tube support bracket on the inside of the keel, centered in the whale tail, but down about 5/8″ (this measurement isn’t really that critical for Fixed Gear aircraft). We also mounted the Roll Trim motor through the whale tail, and the control bracket to the […]

Nose Access Cover

These are now pre-molded at the factory. We’ve cut the 5/8″ lip for the flange onto the fuselage, and sanded the door to fit. We have done some finishing work with Cabosil, filling the void between the hatch and the flange. This is accomplished by duct taping the cover and the pressing it down into […]
