What's wrong with this picture?

[Bob Reeves]

Or is the question "What's right with this picture?"

First correct answer gets a free hot dog at Brodaks next year.

[Bob Hunt]

It's not electric...   But, to answer the real question, nothing's wrong; the model just has a reverse pitch (pusher) prop. Much easier to do in electric, however...

Looks like a pusher prop to me. Did you put in a reverse crank?

Reverse cam. Bob, You could have just put the carb on the exhaust side and the exhaust on the carb side, and then you would also have a rear exhaust engine.    Kidding aside, let us know how it works out in flight.

That prop is un-lucky times 6!!

[W.D. Roland]

13X6 on blade
13 or 12 X4 on hub.

is anti clock wise rotation.

[Peter Nevai]

Other than the LG looking like it is well in front of the wing LE and the questionable effectivity of muffler pressure on a 4 stroke, Everything looks just fine. I may have gone with a different prop though, but thats just me. BTW the hub says 13 X 6, It thats Monokote on the fuse, nice job, There is a spot uncovered behind the motor mount though that will need attention. Is that metallic blue or violet? BTW, How do you get at the fuel tank? Or do you?

   Well, there are bunch of extraneous parts on the head of that engine. And the pipe is WAY too short for 6" of pitch - and for 4" of pitch.

Mr Hunt was pretty quick and correct, it's a Saito 62 with the reverse cam from a 120 twin. Only flew it twice today, wind was boiling over the trees and not conducive to trying a new trim setup. First impression is I need to move the leadouts forward about 3 inches and I think my right arm is at least 1/2 inch longer than it was before.

The airplane is a kit bashed Sig Somethin'Extra I built 3 years ago, ended up (for many reasons) not living up my expectations and being put on the shelf. The fuselage is painted with Lusterkote, wings are covered with Monokote. Monokote turned into rinklekote as did the Lusterkote, then the canopy melted in this wonderful Oklahoma sun. Anyway it was already set up for a Saito so drug it out to do test bed duties for my backwards running 62. I'll be flying and trimming this weekend and should be able to provide a better flight report. About all I can say now is it really shows potential.

Peter, You might want to wate till you have seen one of my Saitos run before saying muffler preasure doesn't work on a 4 stroke. The cg is fine it just looks odd with the Saito sticking out the front so far, one of the reasons I hung it up was because I didn't like the way the nose turned out. If it ends up flying half way diecent I'll have to do something with the nose.

The prop is a 13-6 only because they didn't have a 13-7, just as well as the 13-6 is looking like it will work just fine. Launched at 8200, 5.0 second laps on 63 foot lines trying it's best to pull me off the center pad.

This was taken before it turned into a prune..

Very interesting! Today I test ran a Saito 62 that I just picked up. New to me only, it's supposed to have about 30 some odd flights in it. Started right up and sounded good.

I'll be looking for your impressions of the reverse cam, and how it impacts flight handling characteristics.

Whaa..?

Down in Texas they often mount sidewinder engines at 3 o'clock position.

The Otias Lives!
Good luck with your testing.
What plane would you like to put this motor in after sorting it out?

For those of you don't visit the 4 stroke section, this thread is the whole story on how this came to be.. Martin Quartim did the initial research and I just had to try it. Pretty sure this the first reverse rotation 62, at least in the states.

Once I'm sure of the engine and prop it will go in the Latency and I will reverse a 56 for the Somethin'Extra. Actually flying it in the Latency will be a much better indication of if it's really worth the trouble. I've flown the Latency with a standard 62 for a couple years and will be able to detect performance changes much better than with an airplane I haven't flown in 3 years.

HOLY DOUBLETAKE BATMAN!

Bob,  you could have simplified that by going electric.  Then all it would take is a change of props and the flip-flop of power leads.

    Hey Tulsa, what weekend is your contest in Sept. and what is the address of the flying site?

    Hey Tulsa, what weekend is your contest in Sept. and what is the address of the flying site?

Sept 24th & 25th. The address is 8215 E.586 RD, Catoosa, OK 74015. Won't do the GPS much good as the 911 commission keeps thinking we need a new address about every 6 months. Even the old addresses won't put you in right place, poked our original address from 5 years ago into my Garmin and it thought it was down the road in the other direction.

Best bet is to follow the directions on our web site..
