ST 60 rework...

Hi Guys,

Pardon my ignorance, but is there anyone out there that is still reworking ST 60s? I know the STs are a bit out of date what with all of the great new engines out there, but I've got a pretty nice one that is still stock and was wanting to get it souped up a bit.

Thanks!

God bless!

Mike....still plenty of folks that will rework a Tiger....Tom Lay, in sunny/shaky CA is the closest to you, and does a great job. Randy Smith has done several, as has Tom Dixon.

See Ya

Big Jim on the east coast and Tom Lay on the west cost.....OR just plane STOCK

If you want to run them stock. Frank Bowman will rebuild them for real reasonable. He rebuilt my ST 46 with new bearings and a new ring new allen screws and new gaskets for around $30.00 dollars you can't beat that. [email protected]
I don't think he does hop-up work but you could e-mail him and find out.

Unfortunately, due to eye problems, Large James is not reworking engines at this time.

Tom Lay does an outstanding job with Super Tigres, and Randy Smith turns out a good one, too.

My vote is for Tom Lay.

I've send all my (small) collection of SuperTigers to him and have been pleased with the results.

Mike, one other EXCELLENT motor man is Don Blackburn, in Amarillo.
(806)622-1657. I have two ST 56's he rebuilt for stunt that are great runners! He does magic on everything from old ignition engines to ST 60's. Fair prices, short turn-arounds. Highly recommended!

Tom Lay did my ST 60 for my 72 oz "Golden Falcon" in 1990. It now has over 1000 flights. I just flew a contest Feb/04 with the same airplane and engine. There has been no better engine for reliability in my experience. Just prime and flip.

I have one ST 60 reworked by Big Jim and it has been a fantastic engine. I have a second that was reworked by Randy Smith but I have yet to run the engine.

As far as rework on the ST 60's goes. I have never ran one that wasn't reworked but a flying buddy that has about eight ST 60's, ten ST 46's and a couple ST 51's tells me that some of his engines were never tuned and still run great. He makes his own venturis, installs ST needle valve and spray bars and thats it. To watch him fly you can't tell which engines were reworked and which were not.

Rick,

That was pretty much my experience. I had seven or eight ST60. A couple reworked by Big Jim, one was a Layster, the rest were stock. They all ran pretty much the same. I believed at the time that the Tom Lay engine had a bit more poop, but it was pretty subjective. The Big Jim engines were lighter due to some grinding he did on the head and case. But all ran with pretty much the same characteristics. All were pretty good engines as long as the ring held up.

If you have a new or good ST .60 an easy upgrade is put in a Bowman ring. If you want to take it to the next level replace stock bearings with hi-speed type. There are piston mods too, but I will not get into that. The weak point of the ST .60 is poor quality ring. The ST .60 and the .46 are still very good engines. I have nothing bad to say about modern engines, but they can get expensive. Cheers,Dan

Here is Toms PH# 626-964=5724 He also sells the 3/4 oz tube mufflers-Scott Dinger

which particular make and type of hi-speed bearings do you use and can you recommend a source?
Thanks,

Thanks Greg,
I had a look at the site. Which actual bearings do you use for the ST60 or 46 as I cannot see that they are classified by type in the stock list. Sizes are given but which are the high speed types that you refer to? As I am the other side of the 'pond' a makers type number would be useful too.
Thanks

E-mail Frank Bowman for the numbers. Then go to BOCA Bearings web site.
Click on hobby, then click on engineering catalog, and then CERAMIC. These are the latest high speed bearings. Very expensive and not really needed for most stunt work. Certainly not needed in the ST 46 or ST 60.
