The following photos show the process of making plugs and molds for the seat pan and seat back. This process is much the same as the ASH 26 I did on the ISSA Tech Tips page only here I decided to use polyester resin insted of epoxy.
I took a pice of 1/32" aluminum plate and fabed a "Z" shape and epoxyed it to the back of the seat back, inline with the top of the pan. Then I made a cut out in the back of the pan to recive the "Z" plate.
Here you see how it interlocks.
In the front of the seat pan I mounted a 4/40 alen head wood screw. I also mounted a small wood block under the pan to recive the screw.
A little trick I have learned after loosing many a screw in the grass, take a washer and solder it to the screw on the bottom side. No more lost screw!
Seat mounted to pan.
Pilot in seat. Later I will permanently mount the pilot to the seat via a cloth strap hidden under the clothing.
Compeleted assembly.
Here you can see there is plenty of room for battries and R/C stuff under the front of the seat pan.
