Status: offline 		I really like reading about old pattern info. Guess it has to do with my introduction into RC, and pattern being the dominant activity in that era. Would anyone list off their favorite engine used back in the day? We had a guy in our club that had a reverance for the OS 60fsr with perry pump and carb. I never got to see it, just heard the stories. Would anyone else be interested in sharing stories?

Thanks,
turbo

Status: offline 		I have been acquiring engines/plans of the period 'cause I grew up reading about guys like Lowe, Chidgey, Kirkland, Bridi and the rest. I was fascinated with terms like "full house" and "propo" and read everything I could get my hands on. Engine selection was limited at best, but nobody knew the difference. There is a picture of Lowe's original Phoenix in a similar thread with the transmitter next to it. What a photograph! Big 'ol .61 stuck up front, rubber band wing hold-down, and all. There truly is beauty in simplicity. My latest acquisitions include a vintage Kraft .61 (although circa 1972?) anf a NIB pre-'72 HP .61 4-bolt head. Now we're talkin'. These engines are gorgeous chunks of metal! I intend to run them as they were meant. I love the stuff from this period because they are like me: old, simple, and full of hope. Mark

Status: offline 		Enjoyed the pix of the older engines--I still have a NIB Kraft 61/Perry carb along with 2 NIB Webra 61 Blackheads and a slightly used (on a Eyeball) Webra 61 Blackhead. Discovered that the old K&B 61 muffler is almost a perfect fit for the Webra BH.

Had two OS 60 FSR's NIB, but gave them to two guys who promised to use them on pattern planes--they never did though.

Status: offline 		My first .60 sized pattern plane was a Super Kaos .60 back in 1975 (after having 2 Super Kaos .40s). I put a brand new OS .60FSR with Pery pump and carb in it. I still have a vivid memory of my first flight - wow, now I really have enough power (of course any pattern flier will tell you that you can never really have enough power VBG). I discovered that having an 'overpowered' Super Kaos revealed a minor design issue resulting from the excess power: fishtailing. Yep, at full throttle, in straight and level flight, the tail would oscillate from side to side. The fix was simple: just add more fin area. Unfortunately, I never got the chance to make the modification. The radio failed during 3 horizontal rolls and she went screaming through the woods at full bore in a shallow descent. The fuselage (and about 4" of wing on either side) came to rest about 60 feet off the ground in an oak tree. Took a while to retrieve it, but the engine and radio escaped completely unscathed - good news to a teen-ager. There was balsa and monokote strewn over a 100 yard crash pathway in the woods.
The early .60 FSRs had a habit of breaking the crankshaft at the the intake opening, but were great engines otherwise. The Perry pump had wayyyyy to much pressure and had to be closed down to the minimal pressure setting. Once OS got hold of the design they refined it to a very reliable system. I had a Hanno Special with 1700 flights (the bearings and piston/sleeve had been replaced) it was well worn when retired, but the pump/carb still workde great.
Favorite engine? Probably the OS .61VF, but the YS .60FR is a close second. The early YSs required a long break-in (like an hour) because of the ABC piston/ sleeve fit, but they were the most powerful pattern engine of their time (BY FAR). YS did have a slightly annoying habit of continually making minor changes to the carburetor.
Man, lots of great memories.

Status: offline 		Rossi 60 or 61, YS 60, Webra 61F racing longstroke, OS 60 &61FSR are a few of my choices. All are very good/powerful engines. The one that still blows my mind away though is the Enya 60 XF series engines. It is good on power, but nothing can compare to this engine's Marathon life. IT "was" the only engine that I can truly say that if every flight was worth a penny, compared to the cost of the engine itself..... I would have a nice wad of cash in my pocket. This engine payed for itself over, and over, and over......

Another classic.... The Super Tigre G60 Blue head.

Status: offline 		I just read an article by Don Lowe (RCM July/Aug. 1965) where he discusses the development of his Phoenix. He states that his original Phoenix I (accidentally lost at the '63 Nats) and it's replacement, also a Phoenix I were powered by ST 46's. It's successor, the Phoenix II used a ST 56. Don's friend Ray Nugen who also developed a swept-wing design at this time called the "Expinkamental" also used the ST 56 for his prototypes. Cold hard facts here. Thought I'd share a couple of engines that I hadn't known about. Mark

Status: offline 		My favorite two vintage engines are the early Enya and HP 60 engines.

Got 3 of each and still fly them regularly in sport planes. Neither is very powerful by today's standards of course. The HP's are the stronger of the two, but I still have a soft spot for the Enya's because it was my first 60 and my first true R/C engine. My first Enya (which still runs just like it did new) was - at $26.50 - a major investment back then that took a lot of convincing for my wife to agree I should buy it. The first 60's used an exhaust baffle and no muffler. I flew it in my glass-n-foam Kwik Fli III for a long time which was guided by a CitizenShip 4 channel proportional (the flight pack weighed 25 os - due parly to the aluminum cases wrapped around the servos and reciever!).

The first Enyas were prone to backfires in flight which almost always ejected the prop along with the nut, washer and prop driver. Naturally the parts didn't come off all together and I don't recall ever finding anything but the prop! Enya soon came out with a maintenance kit which had all the missing parts! It was a good idea to have more than of the kits with when you went flying - for one thing you could sell one or more to another Enya flier who suddenly needed one. Later when we started using mufflers the backfire problem disappeared completely.

My original Enya still starts by hand on the first flip.

The HP's were - in their day - very strong engines. And they were even stronger with the aftermarket AFM carb (which is shown on the HP mounted on my current Aeroworks Edge 540T).

Great fun reminiscing about the old planes, engines and radios.

Tony
