Jun 10, 2021 4.5 Brakes and Interior Category: Fuselage
Spent a lot of time looking at the rudder pedals and original brake assemblies. The original brake master cylinders won't work for the new brakes. They don't have sufficient volume displacement or achieve sufficient pressures to adequately brake the airplane. Installed some of the interior to get a better understanding of the room and clearances to mount new master cylinders. Should I try to create heel brakes like the original Dalotel or should I try to create some toe brakes similar to the ever popular and well proven RV series. In the end, I think I'm going to go with toe brakes. I'll remove the pointless foot straps from the original rudder pedals and use that area for the toe brakes. This will require some modifications to the rudder pedals but it will be the most effective, with the least amount of modification.

While I was determining clearance for the brakes, I decided to test fit some of the other interior pieces and check my fit in the plane. This was the first time I sat in the plane. I knew that it would be tight but I needed to have some of the interior in to fully appreciate the fit. As someone who's just approaching 6'0", the rear seat will JUST work. I won't be able to sit properly in the front seat and be able to close the canopy. The front seat will accept someone up to 5'9" comfortably or someone 5' 10" if they slouch.

To do this, I built up a new rear seat. The original rear seat didn't survive the accident or subsequent years of storage. The front seat is a nicely formed plastic tub with some padded vinyl. It nicely cradles my backside but it uses up a couple of inches of vertical space. I made the rear seat as simple as possible. It's made from some scrap 4.5 mm plywood used in the spar construction. The back is connected to the seat bottom using a piano hinge. The upper end of the back rests against a cross tube.

Both seat will leave the pilot or co-pilot with very little head room. We'll likely have to wear in-ear headsets rather than an over-ear style.
