Keel Hard-points

The first hard point we made on the Keel is this “house” shaped one on the pilot’s side for front control rod bracket. It’s 5-3/4″ at the peak with a 5″ tall by 5.5″ wide. It’s is attached on the inside of the keel with micro, with a small fillet or sand the edges (we […]

Mid-Bearing Support

In this section we mounted the aileron control torque tube mid-bearing support bracket on the inside of the keel, along the pre-marked line on the keel. With the rear bearing support located, we measured where the torque tube lined up inside the keel and located the 1″ hole on the support rib. We then sanded […]

Control Stick Assembly

In this section we installed the control stick onto aileron control torque tube. On this piece, it’s important to note that due to the saddle connection, there is only one proper way for it to get installed, and that the outside end is threaded to accept the bolt so no nut is required. Also installed […]

Keel Installation

Once the control assembly was installed we permanently installed the keel with structural adhesive and rivets. The manual recommends also installing the speed brake mounting channel to the keel prior to permanently affixing it, and I would recommend this in hindsight, but this is the way Frank recommended it during Head Start. Also installed in the keel is […]

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 […]
