My favorite simulator run is the pre-checkride box. I call it the kobiashi maru. If a student is doing really well by that point, then it's time for some mayhem. The entire crew usually comes out of it covered in sweat, exhausted. The AES Op students are pretty much brain-fried. But, when they do their checkride, they always comment on how simple and hum-drum it felt. I try to throw in some fun too, I've done Snakes on the Sea King, Navigator bursts into flames. Last course, one student went through totally unfazed, I even tossed an orange (grenade) into the cabin, he calmly caught it, turned to the Navigator, our Deputy CO, and said "here Sir, this is for you!" Totally cracked me up.

Re: AT6 Build

I have been busy – but it is STILL in the ‘PLAY’ category …

I noticed that the canopy was suppose to be secured to the Fuse with glue, that 1/2 “ overhang of plastic was just too subtle of a hint!

As I have this plane rigged up for a ‘Removable’ Cockpit with a 1/8” balsa deck – this just was not a viable option.

So I had to line the edge of the decking with a ‘Railing’ – the main purpose of which is to allow me to glue the canopy to something other than the 1/8” decking!
Putting the railing on was easier said than done (of course), as the canopy does not rise up from the deck at a predictable angle. Which meant I had to cut and sand my own railings from a piece of 3/8” Leading Edge Balsawood. (definitely a labour of love)

After that, painting to make it all look like it belonged there in the first place.

By The Way…
I have received a number of comments on my Pilots… Thank You one and all!

Some of the more memorable thoughts included adding ‘Smoke’ coming from the Student’s ears, ‘Tears’ streaming down the Student’s face as well as my favorite – A ‘BARF BAG’! Either at the ready or pasted onto the kid’s face.

A more practical option was also mentioned, that I was actually able to install – ‘Shoulder Harness’s’. After all; we cannot have our boys falling out of their seats during maneuvers – can we?

I’m not sure… but I think that I’m almost ready to get back to the ‘Serious’ building stuff shortly. Perhaps I’ll do some covering or install a servo or two…

Re: AT6 Build

OK Guys;

I KNOW that you have been wondering WHAT I have been up to!

So here it is... my adventures in model building AKA (Also Known As) wood carving - on the tail assembly of the AT-6 Harvard.

Kindly NOTE the subtle changes in the mounting blocks around the Vertical Stabilizer (AKA Fin) - these minor modifications took me a tad over three days to complete to my satisfaction (there was DUST EVERYWHERE!)

'IF' I had the Hollywood mod - I would proudly build it!

Mainly because VERY FEW other fellows have one - and we all like to stand out from the crowd - just a little bit...

But - alas - it is not to be (yet).

For now, I will be content with a Harvard - which is not too common, and add my own "personal' touches.

Because; I also, like to stand out from the crowd - just a little bit...

Re: AT6 Build

OK guys;
I have been busy as of late and as such I have not been able to put the time needed into this build – I apologise for this lack of commitment.

BUT!
I have been working as of late on the wing, pneumatic lines have been run, holes punched where they were needed, Wheels fitted and the three part wings joined to form a One piece 82 inch wing – which is weird because the plans say it SHOULD be an 83” wing...

So – I have been working; just a little slower than I would like…

Joining the three wing pieces was a tad different from my usual builds and I found that I was able to change the dihedral of the wing by adjusting the Joining methodology.

To do this I had to build a ‘Dihedral Jig’. It is a simple, yet effective tool that allowed me to attach the two outboard wing pieces at the same angle (2.5" rise at the wing tip) – which is a good thing in aviation…

Once that was done then I HAD to start sanding all of the bumps out of the epoxy that I used – I like to have a smooth wing! Then all of those little dents and holes have to be filled in with micro-balloon filled epoxy and sanded (again and again) before the covering begins… and I am not done sanding yet!

I’m still NOT in a hurry to finish this build – BUT – I would like to see it fly this year…

We’ll see how it goes…

Re: AT6 Build

Coming along nicely!

I have a love/hate relationship with sanding. The action is therapeutic, the mess not so much. I also tend to run out of patience with it.

Re: AT6 Build

Good Day All!

I recently discovered that I ‘Lost’ my ailerons during my build – which was probably a good thing considering that they have to be customized to fit in the wing… Which at the time I placed the Ailerons aside – was not constructed – let’s call this a comedy of errors that worked to my benefit… (It’s my story and I’m sticking to it!)

I am currently shaping the ailerons – which is actually harder that I thought it would be – the ailerons are built up, ribbed and tapered for the length of them – on three axis… what a pain! I spent almost two hours shaping one aileron today.

But! They are coming… albeit slowly.

What am I talking about?? The inner section of the Aileron is ¾” thick and then it tapers to a thickness of roughly ½ inch (this is in keeping with the shape of the wing). So I have had to taper the Leading Edge as well as adjust the taper on the ribbing as I plane and sand the pieces to fit. Plus I then have to sand the wing to accommodate the aileron – nothing is perfect without adjustments made by sandpaper… RIGHT!??

This is a slow and frustrating exercise as I have to do it on both the top and bottom of the Aileron and then repeat on the second Aileron…

The instructions - were vague at best. (See attached photo)
I have attached photos of both ailerons – one can be considered a ‘Before’ trimming and the other as an ‘After’ shot. You’ll get the idea.

After all of my whining… I must admit that I do enjoy the challenge of making things fit… but it CAN be a pain sometimes!

Ahhh the joy of RC Modelling…

Re: AT6 Build

Well this is interesting... I'm now posting on my own thread as a NOOBIE... here's hoping that the ADMINs get things sorted out soon.

OK after a LONG absence from the workshop (I've been flying) I was able to steal away and get some covering done. Just the bottom of the wing - but it is a start!

This plane was always intended to be a 'Stand Off Scale' so I decided to make the belly VERY different from the top. You'll only notice when it is in the air!

The Top covering will be a classic trainer colour of Yellow - so when I see the 'Invasion Markings' here - I'll KNOW what the plane is doing. At least that is the plan!

Tomorrow... the Yellow begins! (I hope )
