Airplane Trailer



I've been working on an airplane trailer so I can haul my project out of the shop when needed and put it in storage. This will free me up some space to re-cover my wings and remove some of the clutter in the shop and will also take the Playmate to and from the airport when it is ready to fly. It originally started out as a very rusty boat trailer. I wish I'd taken a picture of it before the repainting as the restoration was rather dramatic. My father and I stripped it down to bare metal, and applied rust conversion coating where necessary, primed and re-painted. Left to complete are: painting the C-channels, mounting the center for the nose wheel, building the ramps and putting on the decking. If I get around to it, I'd also like to mount a fuel tank to refuel while at the airport however, that's pretty low on the priority list presently.



Elevator Trim


So I decided to upgrade the manual elevator trim. Not only was I concerned about the safety, it was just a bulky solution both in the cockpit and at the elevator. The basic concept looked like a lawn mower throttle assembly. The old assembly moved kind of rough and when you pushed on the lever the inner wire would flex before it went into the conduit. For my solution, I bought an RAC servo system from Aircraft Spruce and will likely put the adjustment buttons on the top of the stick. For now, I'm just creating the servo tray so that I can cover the left elevator. The servo tray is made out of aluminum angle with some bends cuts and rivets. I was pretty happy with the result especially since I didn't have any plans to guide me.
