4.2.8 Battery Tray

This entry is part 2 of 5 in the series 04 - Bulkheads

The battery tray was modified a little while back in SC. Now it’s time to install it. Before mounting it, I drilled some large holes to accommodate the wiring that will be going from the ground service connector, landing gear controller, master and starter solenoids. Unfortunately, the connector from the landing gear controller to the power pack is WAY too large so it’ll have to take a different route.

Then I had to decide on how to hold the battery in place. My initial plan was to use “J” hooks. Buy I wasn’t sure how that would work in terms of wearing through the battery tray where the hooks went through. So instead, I used some 1/2″ aluminum and created a bracket that screws to the outside of the tray supports that has a drilled and tapped hole for the rod which holds the battery down.

I then located the battery tray between the master/starter solenoids and the brake reservoir making sure that it cleared the nose gear when it was retracted. Once the location was set, I drilled a few holes, mixed up some structural adhesive and pop-riveted the tray in place.

Once the adhesive had cured, I had to grind a divot in the inner skin. The battery I’m using is just a bit too big so I had to make some space. So I removed the inner shin and some of the foam. Then covered it with 2 layers of BID.
