It says on their site if you use their product submit pictures to be posted. Automatic assumption that she used a Hooker Harness in the Pitts. I was already familiar with the Hooker Harness and it was the 1st place I looked.

Very cool, I went and looked after your post. Yep she is there. So I once again have been proven wrong and appreciate it very much. I did just see a different pic on er site I had not noticed before and it shows the harness well enough to go with your 1-1/2" sizing. Which just happens to go well with the strapping I just bout, or vise versa. I am going to pick up some SS wire and commence fabricating the harness. Most of it should be easy enough with exception to the buckle/center piece.
Thanks Anthony.

On second thought I think I will use sheet aluminum and just cut, file, sand, and polish the pieces so there are no brazed joints. But that locking center piece will be a PITA.

Take a look here, it is a pattern for a 1/4 scale buckle but you can scale it up.

That's pretty thin, I'm surprised they're that thin especially in an aerobatic aircraft, but it is what it is... the ones I've seen were at least 2 1/2 to 3 inches wide... I would think the wider harness would be more comfortable.

With the angle in that photo its hard to tell really, but if it were the smaller 1 3/4" as Anthony mentioned, or even the 2"... a 3/4" to 1" strap would probably look just fine in the model.

You know how this scale stuff works, it only takes one thing to be slightly off scale and it starts to look odd even if the rest of the details are spot on, so you are right about appearance is your best judgment; what ever looks right.

Being the nosey parker I am, I went looking for something over at joanns, but she ain't got much that would resemble harness strap... so I went pixel hunting on the web... this site maybe of use to some... look under the "webbing section", you'll see polyester webbing sold in solid colors or patterns, from 3/8" wide to 2" wide, and .04 -.08 thickness... should work for 1/5 scale and up.

The aerobatic thingy is on but I have some concern. Do you guys think it would be wise to remove it for flight?

TomCrump

The thingy looks great, but delicate.

stevegauth30

What are your concerns? That it will depart the airframe? I don't recall, what is it made out of?

WacoNut

Robert,
The aerobatic thingy helps the pilot determine the angle of the aircraft to the ground during maneuvers. Looks great BTW.

I an guessing you have silver soldered or brazed it together and it is plenty strong. The apparatus (thingy) should not induce any vibration into the struts and I would fly with it in place. Looks too good to leave it off.

Later!!

Robert,
BTW: Take a look here for some detail items.

Why yes, it was brazed together. I was thinking the same and second opinions help reinforce ones thoughts.

I have bought several things from there, may be buying the 2.5-1 harness set, if mine don't turn out well that is.

My Feedback: (4)

It sounds as if you have made it strong, so I would definetly leave it on. Looks cool.

Melchizedek

Your plane looks like the real McCoy (if it wasn't sitting on a bench).
Ground/horizon thingy looks marvelous.

How does the pilot use aerobatic thingy, as apposed to eyesight and/or instruments. I know all of those come into play of coarse, just looking for a little clarification. Have always wondered what they were for..??

acerc

Thanks everyone, I think I'll keep it on and if anything goes wrong I can always blame ya'll. LOL.
Uncle, I believe it is used to keep orientation of the airframe as it moves through the air. The last time I flew sometimes it was hard to tell if the airframe was sliding sideways as opposed to the direction it was being directed to go. Having the ground a few thousand feet below and the horizon somewhat ahead was not enough even with the instruments. One has to remember everything associated with an airplane is assumed for straight and level flight with some banking measurements. Nothing to aid in doing a blender, sideslip, waterfall, etc. etc.
And if memory serves me right, one can't really feel this misdirection of movement.

Jaybird

I believe it is positioned such that from the pilot's seat looking out to the left or right, it becomes like a sight gauge. The arms are horizontal, 45 degrees and vertical. Match the lines up to the horizon and you can gauge how close to horizontal or vertical the plane is or how close to a 45 degree up or down line you are flying.

Jaybird

John_M_

That's an "Aerobatic Sighting Device"... its to assist the pilot to fly vertical lines accurately by lining the sight up on the horizon... the yarn is to interpret airflow over the wing, direction and speed.

It looks very nice Ace.. I don't think you'll have any issues with that going into a chaotic vibration; I don't think there's enough surface area in the airstream.... you got to keep it on, just for the sake of it... if you're uncertain, do a couple flybys and if it looks like it shaking, land and remove it... but I doubt you'll have any issue with it just behind the wing strut in its slip stream.


John M,

acerc

I will have an onboard camera of which I could put the ASD in view for the maiden and the first few flights to establish whether or not there is any adverse vibration.

raptureboy

Only concern would be in transport, you know how those kinds of things seem to reach out and grab something as you walk by. You must be leaving a drool trail by now everywhere you go, kind of like a snail trail. Just absolutely stunning.

acerc

LOL! What do you think I polish it with...

raptureboy

I would expect no less from a builder such as yourself.

Cub Flyer Fresno

Oh boy! Monday's coming!

acerc

That it is, sooner or later.
I think tomorrow I will go ahead and paint that cabane cover, I can wait until the pants are ready and clear both.

John_M_

The camera view is a good idea, that way you can see what it does at higher airspeeds... it looks like its pretty sturdily build , so if anything you'll get a cool view from the camera angle, as would a real pilot.... heck, if you get the camera alined on it just right, it may even aid you in your aerobatics... you could even plug the video stream into a jombo-tron monitor like at Air Ventures Oshkosh airshows and let the crowd view the camera feed.
