Thanks Andrew, much appreciated. More tail build tomorrow or Thursday. The build up of the tail boom on this heli has been quite challenging overall. I think I discovered a few new 4 letter words, if that's even possible...

Thanks guys. 30 years in aerospace has taught me some neat tricks...

So, I've been working on the tail and hit a snag. I realized that I had a 5mm tail GB, but needed a 6mm unit. So that's on hold until I get the new GB mid week.

So, I moved on to the sliding side doors. These are a bit tricky on this model because Vario hasn't provided any cut lines (for door tracks) molded into the fuse (like they do on the smaller 212). I made a template and got out my trusty 24" flex scale, laid out some lines. Then I marked the centerline of the tracks on the door. I did a sanity check before cutting, took the door and slid it back, only to find out that the door runs a little downhill when you slide it back. So I marked the fuse where the lines should be. I'll cut the tracks after bonding the inner track supports in. Otherwise the fuse sides are just a noodle after cutting out the tracks.

The new tail box is built and the drive shaft is made. I also finished the primary drive shaft from the mechanics to the tail boom. I'll be cutting the door tracks out tomorrow. I found the sweet spot with the gear mesh. I had shimmed the brass collar to take out the slop. So I figured I'd just machine a collar that was the correct dimension then remove the shims. Works like a charm.

I had to cut the 11.5 inch long door tracks into the fuse today. So I used a couple strips of .020" thick aluminum sheet metal as guides for the diamond wheel. I taped them in place, then hot glued them for cheap insurance. When complete, just peel the strips off and hand finish the slots. What you get is super straight and even slots in the fuse. You still have to use caution and go slowly, but it's way better and following a line free hand...

do you know by any chance if this fuselage is the same size as the heliclassic one?

Hi Klem, honestly, I have never seen the heliclassics 212. This fuse is approximately 7'4" long 1:6 scale, if that helps for a size comparison.

She's starting to look like a 212 now. I got the dog house sections fit up tonight. The aft section fit like a glove with very little cutting required. The front's gonna require a tad more work before it looks right. Numbers were spot on, the main shaft ended up exactly where it should be. At least something went right today I used a compass to mark the full size hole, before I put the 12mm hole in. I'll open up the hole to full size later.

OK it looks really nice. How will you fix the doghouse to the main fuselage? will you make the system hidden from sight or will you just use bolts like Vario reccomends in the plans?

Thanks Klem. I plan to use hidden tabs in the front. I'm bonding in a strip of wood under the side rails, then counter boring recesses for magnets all along the sides. More on that later... BTW, office clips are your best friend...

Barry, totally awesome build. I've learned a lot watching this. Very close attention to detail. I cant wait to see it in color.

I didn't crash. I just ran out of airspeed, altitude, and ideas all at the same time!

Thanks Ron

So I'm fitting the doghouse panels and I want a flush installation with no screws showing. I decided to use a combination of magnets and hook latch. So I bonded a strip of wood under the area where I want to use magnets. Then I drilled a pilot hole for the pilot on the drill to follow. Then I used a flat bottom piloted drill bit to counter bore the area just deep enough for a magnet to sit in. Then I bond the magnet in the counter bore and it sits flush with the surrounding fiberglass structure. I custom ground this drill bit at work because I didn't have the correct size counter bore handy and I had zero patience to wait for the tool to arrive. But I have included the link to buy the correct tool for the job. This makes everything flush and the install looks great. I will space these magnets at 1" intervals along the rail. I'll post the hook latch in a future post.

Thanks Steve I've been super busy getting ready for work travel and getting the Mustang ready for the Edelbrock car show, so the 212 progress has been slow. Here's the row of magnet counter bores ready for bonding the magnets.

LOL, we shall see... They're skinny little magnets, so I sure hope so. I just wanted the deck to sit nice and flush and didn't want to use any screws.
