There is a test on the Ueda .45 in the March 1967 issue of Aeromodeller. Apparently they first were announced in 1963 and had undergone a few improvements by 67, but the test said that although the motor was an easy starter, it had a few faults (like poor quality control in areas like the con rod and sloppy Gudgeon (wrist pin) fit. The actual capacity was .47, but it was no powerhouse. They were `Economically priced' motors.

I have two of the Ueda .15's. As mentioned, no power house.
If you have one I would put it in a sport model and use it. I don't think they have much collector value.
BTW, mine started out life as RC versions. The "O" ring under the throttle melted. Not sure what they were made of. I used a layer of silicone to repair it.
I think your .45 could be bought for about $10-$15 new at the end of their market life. I think my .15's were $7-$8. This is from memory. Old mags would be more accurate.

The Ueda distributor was out of Philly. I went by one day (late '60s) and picked up a Ueda .19 at a great price.

Ueda made a twin plug .55, too. I have one. Veco was one of their design inspirations.

My .19 as a good sport engine...quick starting, adequate power, but nothing more than that.

Ueda never got much traction in the US. Enya and OS overshadowed them. They were Mazda to Toyota and Honda. And not even that good.

Max: The numerals on the lugs do not signify date of manufacture, or, perhaps, any date at all. Maybe a production run, a la OS.

1997 is much too late. Currell

Thanks guys.I just bought a bunch of stuff and this was in with it all.I had never heard of them .The motor looks old school but the anodized cyl head threw me of.Thanks Dennis

Mid '60s my dad picked up a Ueda 09 which we used for our F4U Corsair. That was one of those Japanese kits with the bandsawed formers and spun aluminum cowl. It flew OK until the whole fin/rudder departed company while it was airborne. Made for an erratic last half of the flight.

Another brand I've seen very little of is Fuji. One of our ass't scoutmasters built an all silk covered Nobler and gave it to one of our troop members complete with a Fuji 29. Naturally the kid didn't know how to fly but did have an exceptionally nice looking older sister. I knew how to fly but my sister wasn't as pretty.
