Quoted: No tint that I'm aware of. Just thought of something. Since it's going to be viewed at an upward angle from the floor, put a red light on the M1 side/center of the cabin "ceiling" facing the BH side window, and a few yellowish LEDs on the BH side, angled toward the M1 side. Looking from the ground I don't know the angles, but you can guesstimate, put a shield on the backs so penumbra isn't too harsh, but it could be seen a light is on. The flight lights just do as a "helicopter" scheme is, No need to get fancy if BH and M1 have slightly different timing/patterns for fast night ID. I didn't see your post about successful Window created until just now. I thought I was at end of thread. Looking good, but I'd suggest adding a larger smooth layer on tail football, or maybe 'spherical triangle panels' as on half a basketball (or two lines of latitude form equator to pole, with equator as bottom of triangle, 3D-2D transform) to make the edge/ridge textures look more.. intended? --ETA: Pictures at level like this see through other window, so no tint unless it's recent. https://i.imgur.com/GKGyosQ.jpg  BTW - Nice shoes.

The edges we're looking at could easily be built up by a talc filler, then sanded down with a sponge to match the curve perfectly, need to be sure to not stir/swirl the mix, fold-mix it so no air is in, gets rid of pinholes from embedded air bubbles. |

Update 1/17/19
Velcro is going to make a nice access hatch for us. The student even added a bit of spacing in the inside so that the panel doesn't stick out. Pretty good idea. 
My student was open to reworking the football. She scoffed a bit at first, but then did an excellent job.  Students got almost all the front windows paneled in and ready for glass bending. 
The rocket sled is speeding up quickly. 
Fitting it onto the main fuselage was a bit of a struggle and required some modification to get over the hangers. 
Just a bit too tight. 
Once on, we had many, many off and ons, as we adjusted the places that were too high. 
We had also allowed a gap to develop between the two halves and it wasn't helpful to find that out after several sessions of fitting.
We had a brief moment this afternoon with a former student who didn't get to take an Art class this spring, and she offered to work, so she foamed up our nose for us. 
With the rotor hub up there it's looking pretty blackhawkish .

In reality, we may end up marking it with what fits with our transition scheme. Basically, markings and insignia that allow it to be recognized, but not interfere with the White hawk nose. The transition around the nose will start fading between the front sliding windows and the right side front corner window. From the front, the nose will be completely viewed as Whitehawk. |

Update continued:
The football being sanded and prepped for repaint. I'll tell you that the student teacher thought this level of scrutiny from ARFCOM surprised her. I told her not every criticism can we make better, but what we can, usually raises the bar on the projects.  Needing another coat of paint. 
The nose ready for shaping. 
We jacked up the rocket sled and started skinning around the edges on the fuselage top. 
With the skin under the edge of the sled, students went and laid out and punched more rivets. Notice the system....punch, drill, glue. They were pretty fast at this with this many people able to help. 
Finally, the first brush strokes of paint being applied to the tail.

 SPACE SHUTTLE UPDATE: The capacitors aren't big enough to fix our space shuttle problem. The new plan is to rework the old code with out interrupts. He thinks he has a plan on where to correct the old code to work with the IR button. If that doesn't work, we will just put it back to the way it was. He returned the wiring to the original set up, so tonight he will rewrite the code and we will try again tomorrow. |

We will see. Signal lines, just a small cap between pin and ground, any high frequency glitch will be bypassed, but once the capacitor charges, via resistance of long wire, signal will be high and trigger interrupt. Use resistance as 0.1 ohm and cap at 0.1uF in spice to look at DC response and AC response to a step signal vs RF. For Transistor circuits to preserve DC bias Hackaday with info and pitchers on power supply decoupling/bypass I'm using them interchangeably as they filter step changes/high frequencies, I should be stating "Decoupling capacitors on power supply inputs to both motor driver and microcontroller" and "bypass capacitor in interrupt inputs" Think of the cap at the pin input as a "debouncing circuit" for the interrupt. Also done with software Base interrupt code for Arduino should be checked with current source code, then follow with the arduino interrupt in software low pass above. --ETA: The idea is to temporarily slap them on, and see if it helps or hurts, without a scope, this is the best thing I can think of quick like. Find what is causing the interrupt, if a spike, cap will drop it, could add an inductor inline as well, but those are a lot more spendy than a cap in parallel. |

I'll pass that along to the students who worked on it. Maybe I can squeeze aN hour or two more out of them to do a little paint detail on some of the parts. Maybe some drybrush work.While we were waiting on the timing of the shuttle doors last night, we did a little measuring for the blackhawk. We measured from where the tail needs to be, forward to the main rotor, then we measured out from there 10'. This gives a few extra inches for the main blades. It's going to be really close. . Getting all four blades to fit means there isn't much room for that fuselage to move much.Today we need to get more of the cockpit windows cut out and formed. My front landing gear people need to jump back into their work and extend them forward to our now existing cabin area fuselage. At some point, we need to flip the main fuselage on its back and finish some rivet lines. That will be fun. That may need to happen today.

Update 1/21
A good blizzard will help to make our are lighting dark enough to get the Marine One logo up next to ours. 
We flipped the bird today, and got started on those rivet lines on the bottom. These guys also worked on those front landing gear details.
Rivet work to day was furious. We went through all of what I had left, and I thought I had just about enough. We are only short a couple thousand. I need to find a source that isn't from China slow boat.
Student teacher looking on and inspecting the work.  I showed this guy your comments about how much it looked like the real thing, and it didn't take much persuading to go back and add a few more paint details. 
We were doing well with the plexiglass, getting it pretty close to the right shape, but when we went to cut it...... 
It cracked right as we were finishing. We are going to use this as a pattern and try to cut it out flat, then heat and contour. 
The other major work today was the skinning of the top of our rocket sled. 
They did a nice job getting all the lines to match up. 
They worked to cut out the skin to allow the rotor to freely move 360 degrees. We did this so we could make sure where ever the blades need to go, we can get them there. It took a little work to make sure nothing would get hung up. 
A little spray paint now, before we get too far along.
