Lessons Learned during the build:
1. The engine mount should be glued into the main body tube BEFORE the paper coverings are glued on. Don't wait until the end like the instructions say - there's no reason to and the body tube will deform.
2. Have the nose cone in place when gluing on the paper coverings. They overlap the nose cone and butt up against a shoulder in the plastic. If the nose cone isn't in place it will be nearly impossible to accidentally get the paper in the correct place.
3. The edges of the paper coverings shouldn't overlap the balsa fin edge when you glue them on like mine did, but should be nearly flush with the edge where the nacelle meets the wing. Check the image for decal placement and note where the embossed areas end and where the decals will go near the nacelle.
4. Pre curl the paper coverings before gluing them on to avoid accidentally folding the paper during gluing. I didn't fold mine, but it was close. I was pulling pretty hard to try and line up the edge of the paper but the glue held it firm.
5. Check to see if your decals are stickers. They put stickers in the kit for a while before discontinuing the kit completely. I'd recommend Excelsior for new decals either way. Order them after you paint the rocket gloss black so it'll force you to wait a few days while the paint completely dries. No need to sand the gloss paint, just give it a few coats and it will be smooth enough for the decals.
6. Don't try and put on the decals if they're longer than a half inch. Cut the individual images out and put them on separately, otherwise it's EASY to wrinkle them and then rip them beyond repair.
7. After decals dry, cover with a matte clear coat and the final finish will look MUCH better.
8. Apparently the bottom fins are only used on the trainer version of the real life plane, but they're almost certainly necessary for the rocket to fly correctly. If doing it over again I'd glue the upper fins just outside the fin line, and the lower fins just inside the fin lines.
9. If you do a build thread, ignore RocketMan Dan's comments. He's only trying to get a rise out of you by pointing out flaws that don't exist.
