It's not even 8:00 a.m. and you've already made my day.That is the funniest thing I’ve heard all day!
Not yet but plan to 3/23-24 looking at 1700 feet to start with.That looks like a fun rocket. Have you flown one before?
I have been using PC Super Epoxy. It sounds as the PC 7 is similar. The Super Epoxy isn't hard to mix. I've been singing the praises of it for a couple of years. For the same reasons you mentioned. Try the Super it's a joy to work with. Makes great filets.Everybody in my house has the flu. I called in to work so I could uber them to DR appts., pharmacy, etc. They all fell asleep at noon, so I snuck downstairs, pulled my Goblin scratch build off the printer, and started assembly:

Fillets Done!
On a recommendation, I purchased a small amount of PC-7 Epoxy from Amazon (for my Punisher/Cherokee builds). It's really thick and won't run at all, but one must be committed to mix this stuff b/c you're gonna get a workout. I taped up the fins, mixed the goopy-goop for about 5 minutes, then started doing fillets. I have to say this stuff stays put. You just have to be careful and very clean. These have to be the best fillets I've done. I was able to do all 8 joints in one go without worrying about ooze. Once the fillets are cured, I will start filling layer lines, sanding, and priming. It still hasn't cured, so I'll have to report back on the result. If the results are as good as the claims, PC-7 isn't bad for fillets. I've been using System 3 QuickCure 15 minute, BSI 5min, and CA for most of my builds and this does not cater to my ADHD but if it works, I can integrate it into my build process.
I should be able to get color on this by Friday! It's nice to be back in build mode!
Oh! I almost forgot... I got my Eggtimer Quasar kit with LCD receiver, LCD-GPS Module, and Voice Module. I'll be assembling that this weekend, if the family is feeling better.
Not sure. I tried 20gm and that was way too much. I mixed it for about 3mins with a popsicle stick (I thought the stick would break) and then started applying. I found that I needed to take my time because it's really sticky and messy. If you look at it hard, it will stick to your eye. I started by putting a bunch in the fillet, then scraped some excess off to keep the mess down, one full pass from forward to aft, then finished up with aft-to-forward and yanked off the tape. By the last few, I was dabbing in little bits at a time, cleaning as I went. That worked much better and the cleanup for those fillets was much easier. 16 hrs. later, it hardened up nicely, but the texture is a bit rougher/bumpier than with the System 3 and fumed silica. Because it's so thick, its not going to self-level. If I shaped some into a cone with a curly point, I'm sure it would have cured the way I left it. I might try something smoother next time like a spoon or socket to pull the fillets.I tried PC-7 for fillets once (I had some on hand for some other reason I don't remember) and had a lot of trouble smoothing it out. It stays put so well that it just didn't want to go where I wanted it go, dragged what I'd already managed to smooth along, then sprang back a little. I found it a maddening experience. Almost as bad as the epoxy putty stick I tried once. I wonder what you and I did differently.
Incidentally, this is the stuff not to use.
With epoxy putty I've dipped my finger in rubbing alcohol and smoothed the surface with my finger. I wonder if you could do the same thing with this epoxy. You could do an experiment on some scrap balsa.Because it's so thick, its not going to self-level.
Cool! Take a bunch of photos of the nose cone before you sand it, if you can. I'm interested in exactly what shape those were back in the day.Snagged an original Mini Bertha on Ebay. Listed as missing a couple of parts but they were in the body tube. Started the build tonight. It's being rereleased this year but as a snap together. I'm glad to have an original. Decals look pretty good.
Isn't it elliptical?Cool! Take a bunch of photos of the nose cone before you sand it, if you can. I'm interested in exactly what shape those were back in the day.
