Scale 50cc Scratch Build From My Own Design Revisited

Tonight I filled in the seam between the canopy and the hatch. I used canopy glue to install the canopy, and since it stays flexible, I was afraid just to go directly over it with polyester glaze/filler, so I tried something new. I mixed up a small amount of the Z-Poxy finishing resin and added milled fiberglass to it until it was a paste. I had tested this out the night before on a scrap of canopy and it really stuck well. I masked both sides and smeared the mix on with my finger. I left the tape on when sanding so I wouldn't sand anything that didn't need it. Once I got close to done I remasked it a tad farther away and sanded again to clean up the edge. After that I went over it with a polyester filler/glaze and then sanded that. I remasked again ans sanded to clean up the edge. I may spray some primer on it tomorrow if I have time.

I took the hatch to my shop today and sprayed some primer on it.

After masking I started by spraying around the canopy area with some black primer. After that dried I used my Nason 421-19 primer and gave it a coat around the canopy, since I had done body work there I wanted a little extra. After that flashed off I sprayed the whole hatch with two coats.

Beautiful plane. Just went through this thread. You do amazing work. Thanks for sharing it with us. I cant wait to see the finished result

A couple more of the hatch.

Not much to show for this week even though I did manage to work on it a little every night.

I used a Balsa USA laser cut servo mount kit to mount the throttle servo. I had to mount it to the top of the engine box to get a straight shot to the throttle arm. The linkage in the picture is just temporary. It will probable get a turnbuckle since I need to order some anyway.

I also cut the cowl for header clearance and drilled holes for the accessing the needles. I came to the conclusion that reaching the lower cowl bolts is pretty much impossible with the header on. So, I decided to make two small access hatches to get to the bolts. I didn't take any pictures of the work on the cowl for some reason so I'll take some tonight.

No problem putting polyester filler/glaze over epoxy? I know polyester resin over epoxy is a problem. Good to know! You are doing amazing work!
