Well that's not something you see everyday...

During a recent pilgrimage to Boeing HQ, took the factory tour where sadly photographs are forbidden. I did though get a chance to see a Dreamlifter takeoff in the rain, video right here:

They use the Dreamlifters (fleet of 4) to bring the various parts of the 787 (think fuselage, wings etc.) to Everett for final assembly and test. Very impressive. Turn your speakers to 11 for full effect.

What the heck?

Update as of 12 December 2016 - Flight Illusion shipped me a replacement GSA-125 some time ago and I'm happy to report it works beautifully.

Back again.

Work events have kept me away from the build but that has not stopped me buying parts and longing for the day when I can have a clean run at the sim.

First up, I ordered a couple of more realistic standby gauges from Flight Illusions, to replace the separate air speed and altitude gauges that were in there (anyone want to buy them?)

The GSA-125 combined airspeed and altitude indicator:

And the GSA-RMI-B:

Both for the princely sum of 1014 Euro (not cheap). Order was placed June 10th and a delivery window of 3 to 4 weeks was given. Well I know how Flight Illusions works, I doubted I was going to get it them that quickly.

Almost 7 weeks later, on 27th of July I contacted Flight Illusions to see what the next delivery window would be. I was promised the following week.

Four weeks later, I checked in again - still no sign of delivery. On 22nd of August I was told the missing part was in, "expect delivery next week".

30th of August received an email advising of "issues with our standard courier". To be fair to Flight Illusions, when they resolved the issue, they expressed the delivery to me.

9th of September, the gauges arrived. And they look stunning! They really have done a fantastic job on these units. Except...

I noticed some excess glue on the glass of the RMI-B. Also, the GSA-125 refused to cooperate after assigning a new ID to the unit (as per the instructions provided).

Contacted Flight Illusions on September 13th asking for advice. No response.

Contacted Flight Illusions on September 20th expressing my frustration. No response.

October 3rd, still nothing. I don't know what's going on with the Flight Illusion folk but until they get their act together I would advise buyer beware. What the heck Mark?

Unlike my experience with the good folk at CPFlight. Given the favorable dollar/Euro exchange rate and a recent bonus check burning a hole in my pocket, I decided to spring for the forward and aft overhead panels. Ordered them on August 24th, was advised that the units would ship week of September 7th, received the packages on September 14th.

They are beautiful! And very sturdy. I opted for the overhead panel covers and the combined heft of panel and cover is impressive. I'll need to have a sturdy frame to support the weight.

Plugged them in, made a simple configuration change in ProSim and everything fired up perfectly. I cannot think of a bigger contrast between 2 vendors. Claudio and Paolo have done a fantastic job with the overhead, plus they have great customer service. Laura from CPFlight kept me up to date with the build and ship dates, they really are the gold standard of the sim building world. Now if they would only build a motorized TQ, I will junk the POS I purchased from Revolution Simproducts and will buy theirs instead.

What else? Well the twin yoke build is still sitting in the workshop in pieces. I got it to a point where both of the control columns and yokes were mounted, only to discover that the heavy duty screen door closers don't have enough strength to pull the assembly into place. Next attempt I'll take out the dampers I have in the current control column and will try those.

Also (for reasons even I can't explain) I got obsessed with dropping in an intercom. No idea why - if I ever finish the build I can't imagine anyone sitting in the right hand seat with me. Nevertheless I sprung for a couple of Ruscool units:

Bottom line - I'm itching to get going again.

This Bird Will Fly Again...

Getting ready to complete the mechanical work on the control columns and the obvious problem slowing me down is I only have 1 control column. And it is one of my own design with a replica yoke from Routech.

Thinking of the cost of a first officer yoke, shipping from Europe and the associated metal work, I figured it would be cheaper to buy a real one. Over the Christmas break I found a beauty on eBay but was outbid ($676 for a control column and yoke? Madness). In the New Year I spotted another that looked a little tatty but good enough for my purposes. I was the only bidder and snagged the devil for $500. And here it is:

Once it is all hooked up I'll strip down the old paint and get it in the same shape as the captain's side. Before taking it all apart I set it up in the test frame I've been working on to see if the control arms will pull the weight of the column back to center. It does. Won't know for sure if it has enough umph until I get both in situ but for now I'm happy with the result.

Inspecting the column there's the obvious problem of the pivot point. Looks like the bees knees but won't work with my simple design. Take a look at the business end to see what I mean:

 

The "torque paddle" (if that is its name) must fit into the cross-member that connects to the captain's side. Instead of going industrial strength, I'm going to be using bevel gears and 1/4 inch steel rods. Bottom line, the green bit has to come off.

I wanted to do it in such a way that wouldn't damage or deform the control column. For this reason I couldn't simply cut it off. Instead I removed the paddle then drilled out the 8 aluminum rivets (yes 8 - they build these things to last) that holds the piece to the bottom of the column:

Even with all the rivets out I had to "persuade" the cast aluminum piece off with a hammer. Taking it all apart I was surprised to discover the vintage of the kit. Check this out - the thing is almost as old as I am:

Which means this rig probably came out of a 727 and not a 737, since the first 737 didn't fly until 1967. No matter to me. Very curious though as to the airplane it came off of, where it flew and when it stopped flying. It will get to fly again, albeit virtually...

And here is the dis-assembly complete:

The mustard looking shaft twists as you turn the yoke. I'll keep the upper assembly since it works fine. The trick will be attaching this bevel gear to the bottom of the shaft and aligning it with the cross connector to the captain's side:

Good news is the aluminum shroud that fits in the floor is in great condition. I can use it as a model for one I'll make (probably out of fiberglass) for the other side. It looks like it has the 10 degree forward tilt on it - interesting:

Back in the Workshop

Alrighty then, Christmas and New Year out of the way, back to work.

I've been rethinking the design of the control column mechanism, specifically the self centering . It's overly complicated for something that it is relatively straightforward. Taking cues from what others have done, I'm now experimenting with a simple "pull me, push you" approach.

First step was to saw off the end of the screen door closing mechanism and to put a thread on the rod:

The thread allows ease of adjustment to get the control column center just where I want it. Next I made a simple bracket out of HDPE (High-density polyethylene, the stuff quality chopping boards are made of) to anchor the other end of the closer to the frame. HDPE machines very easily on my table saw and offers up a low friction surface:

With the closer attached to the swinging arm I tested the resistance. Feels about right but I won't know until I have it loaded with the control columns, yokes etc. The idea of this design is that when the arm swings towards the closer, the rod passes through the opening in the swing arm. When it goes in the other direction, the end of the rod engages and pulls the arm back to center:

I'll make up an HDPE bracket for where the closer rod ends meets the swing arm. At this point just testing the concept. So far so good. Next I'll mount the control columns and yoke for a fuller test.
