My servo washers arrived today, and I already installed them. I'll likely be home tomorrow due to the snow storm, so I hope to get something else done. I want to replace the tail belt because I bought this heli used and have no clue how old the present belt ist. I already have a replacement; better safe than sorry. Other than that, I may start on the cockpit. I certainly would like to fill and sand that seam in the body and close those stock landing gear holes, but since that will have to happen in the garage I'll wait for warmer weather. Today would have been perfect for that - 60 degrees! But of course I had to work...
Don has sent me a matched set of blades; once they arrive I should be ready for a test flight!

OK, the belt has been replaced and the test rig is ready except for the main blades. With two 3300mAh 6s batteries on the stock battery tray up front it's a tad nose heavy, just as it should be for scale.

This is where I am so far with the cockpit. The center console is made of 0.5mm plywood with balsa dowels around the corners. The floor is 3mm ply and still needs to shed some weight by cutting away most of the inside and covering it with 0.5mm ply, but I first need to know where the seats end up. And for that I first need to build the seats - maybe tomorrow.

Today I took advantage of the almost spring-like weather by spending most of the day in the garage filling and sanding the seam between the fuselage halves and the stock landing gear holes. It's ready for primer now.
Question: What primer do you guys recommend? Painting will have to be done with rattle cans.

Use the same brand primer from whatever brand of rattle can paint you decide to use. Whatever their sandable automotive primer is, use that.

Sorry, I'm not sure I understand what you mean. Are you implying that I could use those rattle cans they sell at places like AutoZone? I actually never thought of those, but that sounds like a good suggestion - if that's indeed what you have in mind.
I was always thinking along the lines of Tamiya or Model Master paints...

Yes. And maybe this
http://www.autozone.com/collision-bo...68005_0_168530
for the color coats. US paint types may be different, but usually you can get either acrylic lacquer (as above, or enamel).
I used acrylic lacquer for some of my models. Maybe Google automotive paints to see the differences between the two main types of can-spray paint.

I was referring to typical rattle can brands... If you're using Krylon, use Krylon primer, Rustoleum = Rustoleum, etc.

I'm not really a fan of the Model Master enamel paints. I do like the Tamiya acrylics, especially for weathering foam models, but it would be difficult to get good coverage on a 600 size heli in gloss colors.

I test-flew the mechanics today, and it flew great! I had to increase the maximum collective pitch in the BeastX to 10 degrees, but that was all that needed to be done. The blades I received from Don are perfectly balanced - thanks!
Throttle is at 85 percent on my YEP 150A, simple governor.
The only downside is that I have a bad bearing, making a high-pitched noise. When I got home I removed the main shaft an spooled up the bare motor, and it turns out the noise is coming from this brand new Align 730MX 850kV motor...

Started to make some seats today, using plywood for the frame and cardboard from a cereal box (our cat food comes in bags...) for the curved seat itself. I'll need to add two more layers to stiffen it up - so I have to eat more...

Looking good!
Did your test rig include ballast mass to equate to the fuselage? I'm still thinking about c/g and the possibility that to get OK c/g the lipos may intrude into the cabin detail area. With your physics background you should be able to do some moments calculations on the empty fuselage and relate that to mass placement on the test rig!

No, no ballast yet. I had made so many changes to this heli since I last flew it that I figured I'd better not make that additional change right away. That piece of wood in my test rig is already pretty hefty, and I did use both 3300mAh 6s batteries, as I'm planning on the scale machine as well.
I'm not too worried about the batteries needing to be too far forward because of the cockpit detail which adds some nose weight.

I got a whole bunch of fantastic photos from a fellow at Swiss Helicopter AG, the company that owns and operates the particular heli I'm trying to replicate...

Got my motor bearings replaced (thanks nightflyr!) and will re-install the motor on the weekend. Too bad it will be way too cold and nasty to fly...

I just installed and tested the motor, and it's so much quieter now. The high frequency vibration is also practically gone. Thank you, nightflyr, great job!

I hired a pilot a few days ago, and he finally arrived. He showed me some great recommendation letter from Rodan:

He's already busy inspecting the machine. I'll try to convince him to dress more casually in the future, though.

I also just received some heat-formed landing lights from Nelson:

Good to see there's a few of those still floating around out there. I'm sure you'll have him looking like a proper heli pilot in no time!

Apparently these guys wear whatever they like when flying, even shorts and T-shirts:
https://www.helifreak.com/showpost.p...9&postcount=72
Well, for whatever reason my pilot is a bit particular about exposing his knees and elbows, and insists on long pants and sleeves even in summer...

How can I get full-size pictures to appear in my posts, instead of just the thumbnails? I just can't figure it out...
