Astro-hog

I used to go to RCUniverse, but got tired of being kicked off the air while there. Seemed it was OK or No-K there. Never knew one minute to the next. With a few exceptions, seems to be same group here.


What I need, and got left off hanging, was the wingspan to some 1960's era or 1970's era SIG or earlier Astro-Hog. NOT as per box, but need an actual measurement to 1/16th" +/- off the completed A/C or the plan. Any other places would be OK too, for need wing chord, dihedral angle and overall length.

Box measurements are notoriously wrong.

I am curious as to why? or what for?
I remember a number of us leaving panels off to get a shorter wingspan for more performance before. In the two I had built previously, it was easy to wind up sanding and shaping a little too much off the wing tips or having the ribs a little closer together causing the wing span to be shorter. 1/16 if a inch falls in the range of someone sanding and shaping the wingtips differently. I can see lots of planes being as much as 1/2 an inch off from each other, even from the same builder. I think the one time five of us had out Astro Hogs together at the flying field on the same day, they were all a little different from each other, and we all had different wing tips.

the plans could vary over the years, it depends on how SIG copied the plans. If a third party scanned and copied the plans, the overall size can be off a little too. SIG did change the design and plans over the years from the earliest models.

Howell:

Saw your mention, but after searching, came up with nothing.

You got a good URL for the place?

I just measured mine. 5 feet 10 and 5/8 inches. The tape was tight tip to tip.
Plane was built by Bob Yohanas now deceased.

I see. That is about the smallest W/S yet. You happen to measure the chord also?

I have a Sig Hog and an Original 1959 Dmeco models Astro Hog, they are about the same width but the older Hog has more dihedral.

Dmeco, Debolt Model Engineering Co. NEVER produced an Astro Hog. This model was made by Bill Effinger's Berkeley Models. Anyway, the original model had 72" wingspan plus or minus 1/16". I have the plans from Aeromodeller plans service.

As mentioned,

you had better check the label on that box one more time, for the A-H came out in fall of 1956 and showed up circa 1957 across the Los Angeles basin. Is mentioned in the noted article text where it went then.

I got out back someplace the full bundle of originals for plans by Hal DeBolt, and articles as to what actally was produced, and the name Astro- flat does not come up.

If you use the 1/2 widths for wings as per plan, add in dihedral angle, you will not come anywhere near to 72 inches as stated upon original plan.

The older Hog did not have the same radio gear inside, it was a high wing put out by Veco later on. Thus the need for high dihedral angle.

Wow, you couldn't be more wrong. http://www.youtube.com/watch?v=eovDcg6TxZs This has been verified by many old flyers as a geenie Dmeco Models Hog.

Cherokeenut, Your dad probably added that decal to get people to ask questions or he might have thought it looked nice on that plane, but that's from DeBolt not Berkeley.

I'm sorry, but Berkeley did the first Astro Hog and then Sig updated the old design and kitted their own version.

By the way, your dad did a nice job on that Hog. It's been around a long while. I had forgotten about the orange wheels, I think they were by Bonner.

Have to agree with Edubarca- I've never seen any documentary evidence of a deBolt Astro Hog kit.
