Trimmed and aligned gear leg fairings


Once I trimmed the trailing edge of the gear leg fairings I put them on the landing gear and used the engine hoist (attached to the engine mount) and the tail lift to level the fuselage.  

I used my very handy laser plumb bob to mark the fuselage center line on the floor. I then marked a reference point on the gear, made a parallel mark on the floor and put a string around the fairing. With that in place I could move the fairing to line it up with the aircraft center line.

The laser plumb bob made the whole process fairly easy:

Wingtip lights, landing gear leg fairings and parachute knockout panel


I finished a new knockout panel for the BRS parachute. I used the original panel as a template and made a new one that exactly fits my installation.

Knockout panel temporarily in place (after the parachute and rocket are installed the knockout panel is secured in place with silicone so it will easily depart the aircraft if the rocket is fired.):

Drilling the hinge to the outboard side of the right landing gear leg fairing:

I sanded down the filler I had put around the recess where the nav / strobe light lenses mount. I put some protective wrap over the lenses and stored the wingtips for now.

I reinforced the cut out area that gets clamped to the landing gear leg with one layer of fiberglass tape and G-flex epoxy.

Primed BRS fairing, more wingtips, and started on gear leg fairings

I wasn't happy with the finish on the parachute fairings from the Ekopoxy so I sanded it down and re-coated with Eastwood Aerospray  2k gray epoxy primer - much nicer finish!

Just after painting:

Turned out great, looks nice with all the tape removed:


Working on platenuts to hold wingtip lens:

Wired Deutsch DTM connectors to nav / strobe lights. I also enlarged the hole in the wingtip for these connectors.

Nav / strobe lights pictured and I also wired the tail nav / strobe.
