Motor mount dimensions trivia

Can someone tell me what motor has 1 7/8 distance between mounting holes across the carnkcase and 7/8 between mounting holes on each side?

I came into posession of a right-flying Magnum that has the above measurements. I would love to find out what it's like to fly stunt "the right way" but don't know what engine fits those mounts. The plane is at least 10 years old so I'm sure the motor has to have been around in the late 80's, early 90's.

I have seen a plane fly clock-wise and it was extreamly interesting and unique.

Any ideas?

P.S. If I fly "the right way" can I enter OTS with the Magnum?

Bob Reeves had some lists on his web site, but the URL I got from Garf is no longer working.

This was the old one (Phil Brown still shows it in his collection):

If you can do this, and fly the Beginner's Pattern both Counter Clockwise and Clockwise (back to back), you will forever be my hero. I read that GMA could do the full pattern both ways, but it has to be a brain strain. And I predict you will get dizzy like never before. Steve

PS: What happened to Bob's Stunt Stats? Waaaaaahhhh.....

I dunno! BUT, I have seen George fly patterns in both directions, on the same day, and do it well every time. He used to work with the Navy Judges at the old Navy Nats, showing them what the pattern looked like and then describing the errors he'd seen himself making. He would fly someone else's plane first, going the usual counterclockwise direction, discuss that pattern, then fly his own backwards direction and read the results that the Judges wrote down of what he'd done that time, and critique the scoring forms, more or less.

I never saw that particular judge-training business, but he and others described it to me. The Navy Nats were winding down when I got started going to the Nats if it was close enough I could go, so I did get to a couple of days worth of the 1968 Dallas (Navy) Nats for sure (combat flying days), but I didn't stay over to watch stunt that year, much less to actually enter.

(Yes, Larry, I now recall that he told me he held the handles upside down when he flew a counter- clockwise plane . . maybe I should've mentioned that myself as long as I was already going on at such length. Oh, well, I didn't.)

GMA flew clockwise.

I saw him fly CCW at VSC; he turned the handle upside down to do so..

Kiwi, the 68 nats were at Olathe KS. It was the last nats that I attended. I think Dallas was in 69. Dennis

Some day I will get it updated, maybe...

I have checked out the site but there is only one .50+ size motor. I am pretty sure the motor is at least .50 . ST 46 and 46LA are both too small.

Different engines don't always relate directly to the spacing of their mount holes. The only engine with 7/8" on the adjacent side that has ever been in my own charts (used as the initial setup data sets on Bob's charts, and still containing some errors I keep finding) was the OS Max III, 29/35. But the cross- case distance on those two is 1 5/8". The Fox 59 cross-case distance in my charts is 1.813" (I converted my own Excel charts to decimals because so many of the metric- measured engines had no fractional inch matchups), but the Fox 59 is supposed to be only 3/4" on the adjacent side. That measurement was sent to me -- I don't have an example of that one.

Ever since I learned about glow engines and got rid of my old Sparkie motors (51's, 60's, etc.), the 40 size and a couple of Tigre G-21's at size 46, remained my largest personal engines. I've never owned any of the once-highly- sought ST 60's. My own chart's two "biggies" have been the Veco 45 and the Fox Large-Case 40, both of which dwarfed most others in their own displacement size, at least when they were new & for quite some time thereafter.

If I might add one comment, unless you turn the handle upside down and pretend you are flying inverted you are headed for certain disaster. There are a number of people who learned to fly one way and then tried (unsuccessfully) to convert. It is not a simple matter of saying "I will simply fly the other directon."

I was actually thinking of flying with my left hand to fool my brain(mirror effect). We'll see...

If only I could figure out what motor goes in there...

Dave Cook flys clockwise. As an excercise, he would sometimes take off, flip the plane inverted, then fly the whole pattern as if he were a typical counter-clockwise flyer, beginning with a reverse wingover that started with an outside turn, recovered with a inside turn to upright flight . . . you get the picture.

He tells a story of doing this once at a contest in New Jersey, and then everyone else wanted to try it. Jimmy Casale did it, many others crashed.

Cook once flew against (and beat) Gene Schaeffer in New York in the '60s. They both flew clockwise.

That would have been quite a shootout to see.

I checked a ST .60bb (the one everybody used to use), and it's right at 1.750" x .812", so not correct. Also checked one of the first Fox Eagle .60's (which has 6 bolt holes, tho only 4 are expected to be used...a dual pattern sort of thing). They are 1.875" x .812" or 1.031", your choice. Also not correct. You might look for bolt pattern dimensions on K&B/Veco .61 or Merco .61, trying to think of something common, affordable, and likely to be used in a Magnum. Curtis Shipp could help you on the K&B .61, check SN for the Powertrain Column. I seem to recall the bolt pattern to be rather large looking.

We have two guys here in the Pacific NW that fly with their handles hooked up "backwards". I think they both learned to fly with the handles flat, and turn them over flat the other way for inverted. This (horizontal handle) isn't altogether a bad thing, except that the handle is still hooked up backwards.

From a Judge's point of view, it is more difficult to judge somebody flying clockwise, and I can't promise that the scores would not suffer as a result. Bruce Hunt also proved that it is more difficult to video tape a clockwise flier if the cameraman is a counter-clockwise flier. We have three fliers who fly clockwise, I think. Might I suggest converting the airplane to fly counter clockwise? I think it would be a lot easier. Steve

I would not advise you to try flying it backwards. I saw this happen back in 1964 on the far east island of Okinawa.

Jim Tichy had designed the original "Colossus" while stationed at Naha AFB, had won the Far East Championships with it, and was shipping out to go back home for discharge. Jim didn't want to take the Colossus home, so he sold it to a guy who had recently arrived at our duty station. The guy's name was Larry Barickman.(who is now PAMPA vice president)

Larry decided that he wanted to fly it, so Jim loaned him the Veco .45 that the Colossus was powered with to make the flight.
After much discussion, it was decided that Larry would fly the Colossus by turning the handle over, and taking off to the right.

The idea was that when the airplane was flying upright, it would be controlled as if it was inverted. This seemed to work for a few laps.
Unfortunately, eventually Larry's eyes saw wheels where they shouldn't be, and his brain decided that something was bad wrong.
To make a long story short, the Colossus dug a deep hole in the flying circle, and disintegrated. The Veco .45 was full of dirt, but otherwise unhurt.

you really ought to make the leadouts come out on the side you are used to.

Of course not!
