Just scratch a Rare Bear all for yourself. Use this engine without the collector ring. Only 14 cylinders instead of 18, but without the collector ring I'll bet it sounds a lot like the one you see at Reno.

i think if i had a rare bear with THAT engine in it, i would certainly not fly it at sepulveda basin - lol - at least not without switching over to a HAM radio band. there are so many glitch radio hits out at sepulveda, i'd hate to loose that engine. how much ya think that engine cost to build and where did you find it? on RCU?

**** S L A P ****

sorry 'bout that, i had to slap myself out of a fantasy
and with a bit of help from google, i found a 1/4 scale radial site... and why stop at 14 cylinders? go for the gusto of 18:

It is a Seidel engine. Price? Don't know, but you might find a late model Cadillac for about the same money.

The Seidel engines are as hard to get as the Technopower.

Here's an RCU thread about Seidel sales, and sonme other things.

I've looked at the Hodgson engines before, I don't think they would make very good engines for a flying model.

Why? To start with they are pressure lubricated, not bad in itself but an extra complication when you fly. Next, they are gasoline fueled, spark ignition. Combine that with their high weight and you end up with a boat anchor. Alcohol fuel? If it is mechanically strong enough you might have enough power to fly.

The Hodgson engines do run, but they are intended for display running, not in a flying plane.

It's a shame, they are pretty.

Bill.

You could always try one of these fitted in a WM Dago Red....

The last side wheeler steam ship I was on had a two cylinder double acting "Walking beam" engine similar to your picture, but it was a H*** of a lot larger.

It was a car ferry, named the "Chesapeake," running from Norfolk Virginia to Newport News. It was also the only steam powered ferry, the others were all diesel.

When the bridge/tunnel opened from Norfolk to the peninsula the ferries were all retired and sold.

As memory serves, the Chesapeake was lost at sea in transit to her new home.

Round engines are a bit like helicopters -- lots of sound & fury, while continually trying to shed vital parts.


I remember with affection the Simmonds Nuts Advertisments. A squirrel collecting the loose parts as they fell from the aircraft on take off.

Carrier based mechanics had marked tools because they sometimes were left loose in the airframe with serious results.

A few years back, seven hundredweight of parts were swept from the main runway at Heathrow and a "spare part" is purported to have led to the loss of Concorde.

Shuttle just landed safely.

My own experience of losing parts was with a heavily modified Triumph motorcycle, it shed parts like autumn leaves. Later working on the GT 40 at Banbury Avenue UK for Ford Advanced Vehicles we were introduced to a silly American idea, Locking wire. It was seen as total overkill by most of the workforce. Management bought us locking wire pliers and suddenly it became BRILLIANT idea.

Entropy is the "driving force"; eventually all is chaos, some of us are obviously nearer to that state as are our full size and model creations.

The money maker for Boeing in the deal was getting the Delta rocket line and MDs expertise in spacecraft and military hardware. MD commercial aircraft sales had been losing ground to Airbus and Boeing for years before the "Merger".

I sure enjoyed talking with the MD tech support people in Long Beach, CA. They just had a more friendly stlye than the white shirt/black tie guys in Seattle. Not knocking Boeing engineering and support, they always worked hard and came through with an answer, just the Long Beach guys seemed to enjoy life more.

Status: offline 		This thread was some great reading guys, with points made in all corners. Me, I grew up in the early 40's, and most of you know what that means huh? Yeah, WWII. And with several airbases around I heard a lot of different engines. As soon as I'd hear an airplane I'd run outside the house see what it was. Got to where I could ID a Mustang, P-38, Jug, or Stearman before I hit the door. Squardron formation fly overs by B-17s were fantastic! Even Piper and Taylorcraft "Grasshoppers" would do it for me. Then I grew up, and through somehow wound up as a Squad Leader in the Marine Corps during 1950/51 in the Korean thing...we called it a war. While there, I came to know quite well the comforting sound of those ole Hognosed F-4Us as they showed up to help us out when we needed them most. Now, 55 years later, the one sound that sends chills up the back of my neck are from two synched PW powered Ag-Cats at cruise rpm swinging by overhead on their way to the far end of the Bean patch. My vote is on the Round Engines. Then too I don't have to ride in an open cockpit all day long behind that round devil.

Status: offline 		Thanks Bill.

In the late 70's PW 1340s were getting rare. (In our neck of the woods, anyway) One of our local bush plane operators needed a new engine for his DHC-3 Otter. Couldn't get a P&W, so he ended up putting a Polish Radial in her. We all called her The Polish Princess. She was horrid, sounded not like a proper Otter at all. The Polish engine had significantly less power and never worked right. Did I mention the owner was regarded with thinly veiled scorn by those in the know?

Last night,I looked at the picture of The Blue Angels F-18 doing the afterburner take-off. The question was posed, 'can your radial do that?' Well, a DHC-2 Beaver could, in slow motion. Also the Maule Rocket could do a pretty good imitation........but it had an H/O Lycoming or Continental.

So, the debate rages on. What was the best bush plane of all time?

Ugh! Great Silver Bird leap into sky, swiftly like arrow! Whiteman's Magic............considering density/altitude.

Surely you are not saying the Martin "Mars" was the best bush plane of all time?
