Finished Seat Rib Nutplates; Started Seat Pan Hinges
Today I started out by finishing setting all the platenuts in the seat ribs. This was definately an annoying undertaking and only time will tell if it's worth it. I'm planning on installing my bell-mounted bent-whip COM antenna under the seats. Most people that pop-rivet the seat pans down usually install the antenna under the stick assembly...but I'll put it aft 'cause I think it looks better and it will free up the forward area where everything happens.
I also installed these K-1100-3 platenuts under here for the center flap bearing block. I also discovered that K-1100-3's look ALMOST identical to K-1100-8's...so be careful. I discovered that in the seat ribs I had installed a -3 where a -8 was supposed to be.
Next I started cutting hinges and I drilled them to the left seat pan. The dimensions on the drawing didn't exactly work for me...so I had to shift some of the rivet holes left and right to clear the seat ribs.
Here you see that laterally the seat backs look perfect. You can see here that the brace is centered in the adjustment slots. Some folks have had problems with this...but mine is as good as can be expected. We'll see about the right side later.
Here's the location I mentioned earlier about possibly locating the LET (excpet it will be behind the right seat...not the left one. The ELT fits fine...but there are two problems this this location.
The first problem is a minor one in that the instructions for the ELT have you mount the unit parallel to the trust line for fixed-wing aircraft...and obviously putting it here it would not be flush. I'm also very anal about having things showing in the cockpit...and although this will be obscured by the seat backs, it will still be visible when looking through the rear (fixed) part of the tip-up canopy.
The second problem with this location is the wires. The wires for the remote control and antenna plug into the front of the unit and I'm concerned about them being too close to the seat backs and getting chaffed, etc.
