Not much progress this weekend, because it's just too freezing cold to work in the garage. I added these two little tubes above the exhaust; no idea what they are for. I haven't seem them on any other AS350.

Had another three test fights today, and she flies like a dream. There is still some bearing noise, but much less than before the motor bearing replacement. I still need to hunt that down.
Other than that, no progress as I was on travel for two weeks.

I cut out the additional windows on the pilot's side today, the lower window on the door and the vertical reference window. That's a lot of "holes"...

And here's the inside view. Still have to clean up the cutout in the cockpit floor a bit.

I did a couple of test flights today, using two additional 6s 3300mAh batteries as ballast to simulate the fuselage weight. All went well, but I had to increase my throttle curve (simple governor, not "governor store") from 85 to 87.5 percent to have a decent climb rate with what is hopefully sufficient safety margin. At least if *looks* pretty scale, lol...

This "simple governor" business now has me thinking. I would expect that I have to use the voltage of a (nearly) fully charged battery when calculating my head speed, not the 3.7 volts that are usually used. The reason is that this simple governor locks at the head speed achieved at the beginning of the flight when the cell voltage is some 4.10 volts (accounting for some sagging due to load here).
What are your thoughts?

After flying, I replaced my metal tail unit with the plastic one that does not have the lug on the side. I had removed the upper bolt to get it higher in the tail. Now I secured it with two 3*6mm self-tapping screws and a zip tie. It seems to be rock solid; should hopefully hold up well in flight. I will test fly with this tail next time, and if all is good I'll install the mechanics in the fuselage for some final tests before painting and detailing.

I also painted my skids, using Tamiya gunship gray. Before painting I added the non-slip surface to the steps, using epoxy and some fine sand from the beaches of Long Island.

First test flights in the primed fuselage today, and she looks just amazing in the air! Everything went very well. I got two flights in before the rain started, and now I took her apart to paint her.
I made and installed the tail rotor protector, and painted the head. Once the primer on that tail rotor protector has dried I will give her a very light sanding, and hopefully start painting the body tomorrow.

My 3D-printed jet exhaust arrived today from shapeways.com, and it looks fantastic! I had uploaded lynxman's 3D-printer files that he linked to in his build log on RCGroups. I was a little reluctant to order this, as it came up with a warning that the material may be too thin (<0.7mm) in some places. I had to use the "print it anyway" option to get it printed, and it turned out to be a non-issue. This looks a million times better than the stock exhaust, and it's the right shape for a B3 model.

Painting of the fuselage is progressing. I live in a apartment complex and had originally applied the first coat of pint in my garage, which is underneath someone else's apartment. This caused me some trouble because of the smell, so I had to give it to a friend for painting.
As you can see, it's all white now. He wants to apply another thin coat, and then he'll hand it back to me for masking. A lot of back-and-forth, but I'm glad to have someone who can help me out!

Looks good!

Certainly much better than anything I would have been able to put together...;-)

What paint system are you using? Base coat / Clear coat or an enamel?

Enamel, but I'll apply a clear coat to seal the decals.

Are you using rattle can or do you have a compressed air system?

Rattle can only. I don't have anything better - I don't even have my own place where I can do things like that, so I have to ask my buddies.

I have the facility and equipment. I'll be gearing up to base coat / clear coat an airframe in a month or so. If I can help let me know. I'll be spraying Red, White, Blue and Clear over the period of a week or so.

Sounds great! Based on your username and location, I assume you're literally right around the corner (actually, two corners...), right? Let's talk about it tomorrow.

Spent quite some time today cutting out the windshield. That took longer than expected because it's not so easy to sand the edges to the exact shape, but finally I got it done. I want to drill the holes for the tiny screws before the fuselage gets painted. Hopefully tomorrow...

While checking the size of the decals today I suddenly realized that my particular subject (HB-ZNH) does not have those vents on the side of the doghouse. Fortunately it hasn't been painted yet, so there is plenty of time to correct that...

Getting ready to get this painted. I made a rotisserie to mount he rear fuselage during the process; the canopy will be attached to a vertical stand using the magnets I installed to support the cockpit floor.
