I am planning to tackle a Shark 45 from RSM soon for Classic. (Well what else?) The fairly obvious modern, readily available engines are the ST51 and LA46, plus 4-strokes like Saito 56/62. I have a ST51 in a 67-ounce Score, very similar in size to the Shark and it pulls well. Of course there are the cool $350 engines from PA and Rich Oliver, but without spending that kind of money what are good engine choices for this ship? Vintage ST46/60 are available (I don't own any) but a used one is kind of a pig in a poke.

Mike,
Since you have a ST51 I would go for it. I`ve had one in my Colossus for nine years. 700sqs. You`ll be happy with it.

Too bad the Magnum 53 isn't available anymore. I loved the way that ran. Felt like an ST 60 in the plane. Sigh....
Gordy's right. The ST 51 is a great choice.
-
Ditto ST G51! Much, much more stunt grunt than the LA 46, without a doubt!
-
Not just a ST G51 but a Tom Lay ST G51. Yeah, that's one great engine.

Stalker 51RE
-
Pat Johnston has been using a Stalker 51RE in his Mustang. It's a great engine, though I don't know if it falls into the inexpensive catagory at well over a $150.
-
Just for the record I would regard a $150 engine as "inexpensive." I would dearly love one of the jewels from Randy Smith or Rich Oliver but my engine budget is overwhelmed by my kid's tuition budget, a tradeoff I am not one bit unhappy about but which limits my choices a bit. My ST51 was re-ringed by Frank Bowman and had the head/sleeve joint lapped or milled. It is a great powerplant for under $100, or $130 if you count the cost of the Randy Smith tube muffler. Stalker sounds interesting too. Did not know they could be had in that price range.

I have an RSM Shark .45 with a T&L ST .51 in it. Every time I fly it in front of somone who hasn't seen it, they say wow what kind of engine do you have. :o Soooo, it looks like a match to me!

I have seen Jim's Shark 45, the engine run is great! Jim, did you get to see my USA-1 with the T&L ST G51? AS good of engine runs as it gets!
-
This should maybe be in the "engines" category but what is a "T&L" engine? Is this a tuner other than Tom Lay? And, can somebody direct me to Tom Lay's contact info or a web site where he can be reached or his engines purchased?
-
T&L= Tom Lay. ;D
Tom is a member here. His ST G51 does run different from a *stock* one! Unfortunately, I have not run a ST G51 from any other engine builder, so I can't do a comparo.

Hi Bill,
I have flown several flights on the Leeward Air Ranch P-51 of Tom McClain's. It too has an ST .51 powering it. He did send it to Randy Smith for a tune up. It's run is quite similar to a T&L but, not completely. I never did get to see your USA-1 fly. I'll bet it was a killer performer with that T&L in it! If I ever get another van, I'll build one of them myself! n~

Hi Jim,
Mr. Werwage has suggested that a PA 51 might be the perfect fit for the USA-1. So the next one will have that! ;D
I felt very proud of that plane when Derek said it was one of the very best planes he had ever flown. That was after it was no longer mine.........
I loved it a lot, super easy to fly and gave a feeling of confidence when you flew it!
My ne T&L 51 will go into a .60 size F-4-F Wildcat that Pat Johnston designed for Bill Hummel, and he shrunk it just a touch just for the T&L 51 for me.

FWIW, I spoke with Lew about this plane, and mentioned that I had a Saito .56 that needed a good home. He suggested that this might be a great combo. Now all I need to do is finish 4 other projects and set up the Adjust-o-Jig again.
