Howard Bonner 75% Smog Hog for AMPLAN Build Off

Some preparation before starting the actual build next month.

What I want is a 75% version so it's a sort of scale model and the first thing to do before tackling one of these is to collect all your documentation.

I have the full size plan and copies of the construction articles from MAN February 1957 and Aeromodeller April 1957 plus a couple of shots from the internet. This will give me the outline and colour scheme.

There already exist at least two plans for reduced size Hogs - one in MAN August 1973 and another in Radio Modeller August 1994 but I spent a couple of enjoyable hours scaling down the full size plan to produce my own drawing and structure.

Ah, the sign of a REAL aeromodeller - someone who ENJOYS drawing plans! I spent a pleasant hour or two last evening with pencil, straight edge and french curve on the reverse procedure having decided to scale up the Airknocker drawing from the little A4 rather than tile print it out - glad I did, I enjoyed the exercise.

Nice work Gluehand - hope my little one turns out as good.

Many years ago I actually built an original size Hog but sold it before completion. It had turned out rather heavy and for some unknown reason I had used a foam wing I decided that someday I would return to the design and build it properly. Sundancer's AMPLAN build off is just the excuse I need.

Nowadays I tend to build smaller models and, since the original was quite a chunky beast, 3/4 full size seems about the right size for an electric version.

Thanks Ray,

My Smog Hog was a great flyer, however a few years ago I sold it.....yes you guessed it, due to its "chunkiness".
A small car, small house with an even smaller cellar made transport and storage a handful...
This is my first year of retirement, and I predict that smaller things (in general) will fly off my building board...

(Among many "projects", I'm thinking of a "Spearhead Jr", scaled down a bit, to suit a 0.25cc Schlosser diesel)

This Hog has reminded me I always wanted another Hog.
Maybe an Astro Hog is firming up as my entry.

Will be following with interest. Back in 1959 Charles Riall designed the Rattler for Galloping Ghost, this was essentially a 3/4 size Smog Hog.

My first encounter with the Smog Hog was at a fly in in Marysville Ks. back in the 60's. A fellow from KC came out with one sporting a Fox 59. To say I was impressed is an understatement as he would do verticle 8's with the bottoms about 4' high and the tops at about 50'. These were inside on the bottom and outside on the top. He would kick in the throttle at the bottom of the 8, and then pull it off at the top. I was flying an Esquire at the time with an Enya 19lV, and I could not believe the stuff he was doing with that thing.

Scaled down Smog Hog

Here is a scaled down Smog Hog. K&B .19 R/C with reeds. Span about 56 inches if memory is correct. A great flying model. Here at Misawa AB North Honshu. Jack

Before getting down to building perhaps a little history would be in order. I am sure most of the "Old Timers" who frequent this forum will be familiar with the Smog Hog but for those who are not .........

Designed by Howard Bonner and flown by him to win the 1956 US Nats, the Smog Hog is considered by many to have been the first true competition aerobatic model. From it were developed the Astro Hog, Perigee, Taurus etc. which set the basic parameters for subsequent designs. A Smog Hog (with ailerons) also won the 1957 Nats flown by Bob Dunham.

As an ex F3A competition flier I appreciate Howard's contribution to the class and felt I should someday build a Smog Hog as my small tribute to him. I started F3A in 1967 with a reed equipped, Merco powered Dave Platt Kingpin and finished in 1992 with retract/pipe own designs. Along the way I remember having a Moonglow, Thunderstormer, Bar Fli, Twister, Swinger, Belaire, Capricorn, Meteor, Tornado and Super Star - happy days

Right now, being too old and stupid to be competitive any longer, a little Smog Hog will suit me just fine. I have collected all the materials, covering and accessories needed ready to start building next week.

1) Anyone know Mr Bonner's AMA number.
2) Anyone know the manoeuvre schedule used at the 1956 Nats so I can try some prototypical flying.

Wow that is quite a list of aerobatic models Ray. I never got too heavily into aerobatics, certainly not competitively, just for a few years before I became hooked on thermal soaring, but I did have a Barfly and a Kwikfly III. My favourite though was Doug Spreng's "flat top" Stormer. I looked out my plan recently with thoughts of an electric version and was amazed all over again at how light the construction is - lots of 1/16" balsa. In fact very little in the way of changes would be required to produce a highly aerobatic electric model which would not require large cell counts - probably 3S or at most 4S.

I for one will never forget the Smog Hog. In 1957, Howard Bonner and Bob Palmer (control line guy) did a demonstration tour of southern Africa, the UK, and possibly some other places too. As a model airplane mad kid, I couldnít believe my good fortune when they included Salisbury, Rhodesia, where I lived at the time. Iíll never forget the demos they put on, especially Bonnerís RC ones. He had his Smog Hog (the very one shown on the MAN cover photo in Post #1, I believe) as well as an example of the latest and greatest development, the Astro Hog.

Everybody who saw the models and the flying that day was just blown away by it all. We did have a very active local club, but the most advanced equipment anyone had seen up to that time was one of those ED rudder only cubic foot boxes with the lamp cord and switch, which hardly ever worked anyway. To see what Bonner did with his Hogs was unbelievable. More than 50 years later I can still remember each one of his many perfect flights like it all happened yesterday. Happy days, indeed.

Shortly after that I got hijacked by the usual motorcycles/girls/cars thing, and I never did get around to building a Hog (of either species). But theyíre still on my someday list, and Iíll be watching your build with much interest.
