As this was the first time I have assembled this kit a lot of the techniques were new to me. This was a stepping stone on my way to Estes Saturn V.
Instructions were super easy to follow and make me want to assemble any Semroc kit in the future. No fitment issues, shaping of the fins were done easily with 400 grit sandpaper. I used Estes fin guide to install the fins which made it super easy. The fins were papered (new technique to me) and turned out great, would do it again on any other balsa fins in the future.
If you assemble this kit don't worry about the vanes at the motor end. I used wood glue and it was perfect to tack and hold the vanes until they were all installed. I added drops of glue with a toothpick to help strengthen it in the corners of the vanes.
I tried filling the body tube lines which proved difficult. Once filled they were sanded but as the tube lines were so tight not much stuck in there. Once finished I didn't actually mind the lines, they seemed very hard to see in the end. . It reminds you at the end of the day it is a model.
Sanding was done with 250-450 grit sandpaper.
Primer, Florescent Orange gloss and a clear gloss sealer was applied after decal installation.
This was my first time using water slide decals and most were easy to use after soaking in water and dish soap for a minute. The over the fin decals have a small part you need to cut out but can easily be done with a x-acto & straight edge. I was quite happy how easy it seemed even though I was a little scared to undertake the decal process.
No balsa filler was used on balsa reducer and nose cone, but were sanded with progressively finer paper. I think it turned out great and would consider doing that in future models.
Any slips that the perfectionist would notice come down to user skill, I can't fault any of the parts included in this kit.
Construction Score: 5
It has not flown as of March 19 2018.
Recovery is done by parachute. I like the Kevlar cord & elastic combo. It's a welcome change from gluing the elastic recovery line to the inside of the body tube. In this kit they mount it to the engine mount.
This was a great kit, if you have a chance to pick it up go for it!
