Well as can be expected!Thanks Neil. I hope you are well these days.
I would do 3 motors
Does he use the same adhesive / glue you use? (that white caulk gun stuff?) or just the technique?
From past experiences, I've found CA to be extremely hard to sand. it will sand, but you tend to sand more of the 'bare wood' than the CA soaked wood..
Have you thought of using a light weight balsa filler, the stuff R/C plane builders use? Light, easy to use, thins with water, and no smell!

I usually use a laquer sanding sealer, and it takes quite a few coats and sanding to fill the balsa grain. I never thought of using shellac, I imagine it would fill in the grain better with fewer coats. Is there much difference with the pigmented primer you use and just plain clear shellac? I might try that on my next build.
Nice build thread, I like how you're presenting your techniques. That fillet method looks like it would work well for LPR, does paint adhere to it well? Does it sand at all, or do you aim to get it right with your fingers?
I have a couple questions about BIN if you don't mind. So just to be clear, you only use it on balsa - correct? And second, when you apply it - do you apply one coat, sand, and then another coat and sand? Or do you apply two coats, then sand it good.
Thanks!

I primarily use it on any wood used in my rocketry construction. I use it as a sealer of wood grain so when I sand....before using spray primer, the wood is sealed (giving it even porosity for the spray primer). Also any loose wood grain is also sealed and sanded smooth after using this product. I do two coats...as the first coat soaks in pretty well. Then sand with 220. Make sure you stir it very well....as the solids sink to the bottom of the can. Also, see link in post #64 you will see photos of what I am talking about.
I hope this helps.

How long do you need to wait before sanding and then priming when using BIN?
On your Conquest build, it looks like you applied it to the body tube as well. Seems like it can do a decent job of filling the spirals too.

Thank you so much for sharing this fillet technique. I've very much been in an improve-my-fillets mode. I was thinking of going down the epoxy route, reluctantly, as I am trying to minimize my use of that stuff. Now if I can only remember where I put my caulk gun...
