Maybe later.

Status: offline 		I doubt it. As a rule I first flight a plane with just myself and one other person. One will be busy flying and making comments while the other takes notes on trims, balance, incidences, and mixing. It rarely leaves much time for filming if you're serious about a maiden flight on a prototype aircraft. These are more of a shakedown series of flights rather than pleasure flights.

You're going out with a plane that is one of a kind. It has no construction manual, guesswork for control travels, a C/G that's iffy at best, and you don't know if it will stay together. Just basic flying has to be done for several flights just to get a decent feel for the plane and make determinations about what is good or needs to change. All this stuff absolutely must be done as quickly as possible in order to notify the factory of any necessary changes before the production run is due to start. If you don't do all the work in the beginning, you end up with a lot of really mad customers later, a very delayed delivery schedule, or both.

All the fun, wringing out stuff comes a little later in the process. Now that's the stuff worth filming.

Thanks Pat, looks like it fit in my truck diagonal. I could not justify to buy a new truck “just” because I get a bigger airplane.
…interesting reading of the build progress.

Tom, good to see you are a happy camper about the plane.

Happy landings

Status: offline 		G-Pete;

I don't know if it helps, but the width at the elevators is 40 inches with the rudder extending about 9 or 10 inches aft of the elevators. Unless I get real creative I don't think I'll be carrying my Giles and the Sukhoi at the same time in the pick up.


To All;

One thing of note, this isn't really a build process as much as it is a prototype fit and test process. I figured that I won't be home when the production kits come out so what's getting done here will apply pretty much to the finished models. It also let's people see some of the work that goes into a new plane before it's released to the public. It eats up a whole bunch of time checking fits, making sure parts locate where they should, going over incidences, finding covering errors, taking notes and pictures, and putting all the info together for changes and confirmations. Then going out for about 10 to 20 check flights before getting into any "heavy" stuff. Sometimes it's interesting to see some of the "behind the scenes" process.

"Bookmarking" this thread for later use may be helpful to all when the production kits hit the market. It will make it easy to come back to without searching a bunch of "pages" to find it.

Status: offline 		Incidence Checks;

We've all been there. Get the plane all together, go out to fly and something's not quite right. That's not going to happen with this one!!

I set the fuselage and wings up in the back yard and broke out the incidence meters and the long bar to check it all out. Sitting on the main gear legs without wheels and propping up the tail to within 1/2 degree of perfectly level, I came up with all flight surfaces dead on the same angle that the plane was on. I used the hatch deck for the zero reference. It had the same 1/2 degree angle that I had the plane sittng at so it was good to go for checking the rest.

I checked every wing, maintaining the hatch deck as a reference, and every surface read the same as the deck at 1/2 degree. If I had raised the tail and shimmed the stand a little to hit zero all the numbers would have changed equally and hit zero, meaning that the entire plane is set at a zero/zero incidence reference, setting the stage for some neutral flight parameters that will let a person fly whatever type of regimen that they desire.

I'm posting some pics, but some did not come out as well as I hoped. You'll get the main gist of it, though

Too bad I was not able to make it up to your place and have a look see at it today.

Status: offline 		I can't seem to post any pics at the moment. I guess the RCU server is getting a liitle too much action with all the W/H threads. I post big picture files so they can be downloaded and expanded, so that makes it even harder to get them through, even at 100mbps. I'll post them later.


RTK;
Yes, I checked the tips. There is no wash in or out. Did I mention that I broke out the long bar? The long bar is about 6 feet long. I also use an 8 foot level to do a lot of cross the hatch types of measuring. Neither Di or An of the Hedral family is anywhere to be found. If it anhedarl or dihedral it would be very hard to get the wings on since the roots are recessed into their own pockets. That plus that arrow straight C/F wing tube would make a bent wing quite a fight to install.

What all this means is that the jigs and patterns used for the prototypes are correct for all the important stuff and do not require changes to make them right. That also means the probability of some super straight airplanes is pretty much assured.

I have some photos I'll edit in a little later of the control deflections with all the wings in place. There is no linkage connected up yet so they depict what's available the way it comes out of the box. For those that are wondering if this plane will 3D, the pictures should pretty much answer that!

We spent the day painting the floor in the new building. My wife did all the work, really.

The biggest problem is at 100+ degrees epoxy paint only has about half the working time. By the end of each gallon the stuff left in the tray was like fudge.

I used an old trick and kept the mixed paint in a tray of ice, that extended the pot life a little.
