I am about to rebuild an ST V60 with a Brian Gardiner ABC Piston liner and rod. I want some new bearings and I went to the Boca site, but there is nothing listed under ST V60, there are some likely options, but I can't be sure. There must be someone who knows which option is the correct one?
Is there much point going to anything other than the economy set, the application doedn.t seem arduous, or am I missing something? I suppose ceramic ones won't rust, but it seems a lot to pay when after run oil is so cheap!

Andrew,

Andrew; I would go with the ENK-044 that is listed for the old ST60. It also gives the number of the bearings in that kit, so you might want to check your numbers to make sure. It is listed at the end of the Super Tigre listing on their web site.
I always go with the economy bearings as they seem to last as good as any.

The ST .60bb used in CL stunt was never referred to as "ST V.60" in any advertising or on the box, so there is no reason Boca would use that model designation in their listings.

The Boca Economy bearings certainly didn't work on my Saito .56, as it only lasted for one flight.

then I was told to use the stainless steel ones.

Hey Joe; I have been running economy Boca bearings in my Saito 90 twin for the last two years without problems. I have also replaced them in other peoples Saito 82's that are running just fine. You must have gotten a bad set. I have used them in many other engines also.

Thanks Jim and Joe, maybe I will go for the economy bearings and see how they go. They are hardly stressed on something like a stunt 60. Thanks Steve for putting me right. I am not a Super Tiger expert and I really know very little about them. I just looked at the side of the engine and there was a big V with the 60 designation tucked in it. So I assumed (wrongly) that the engines title was an ST V60 an easy mistake to make if you are not in the know!

Happy New Year everyone,

Andrew.

The front is the same as ST46. It's a 607 which is 7mm ID, 19mm OD & 6mm wide.

The rear is a 16002 which is 15mm ID, 22mm OD & 8mm wide

Just noticed Brian that 22 should read 32 OD on this bearing.

I rebuild these all the time, I recommend you use a 607-2rs (rubber sealed) and you can buy a chrome or SSteel rear 16002 if you do not want the ceramic. with your afterrun rust and corrosion will be kept to a minimum , and the chrome or SS rear bearing s are much cheaper than the ceramic

I have had very good results with the Boca "economy" bearings in 40VFs. They are certainly better than the originals.

Hello Brett,
I am curious re your comment on the ST 60 saying that it didn't perform as claimed in the 1980s. Could you elaborate, or is this one of those dodgy subjects? If so please can the rest of you refrain from stirring the pot, I just want to hear what Brett has to say, I don't want a slanging match!

Thanks,

Andrew.

Hi Andrew,

Since I believe you are referring to Brett's post in my DR .60 thread. From what I gathered, the ST .60 worked well and was very good in its day. They can still work well today! Richie won the World's in 2010 with one IIRC.

Problem is, getting that "Top 5 NATS run" was not so easy every time. Head shims, venturi sizes, props, nitro, etc., often needed fiddling with. Probably not enough to bother the normal stunt pilot, but not always the "perfect" run.

I have not used an electric yet but, I feel the pipe systems, set up right, give a near "perfect" run almost every time. Not as much fiddling to do with those it seems to me.

Later
Bill

I would rather not kick the hornet's nest again. I would note that no one ever (now, or in 1993 when it all started) said it wasn't a good stunt engine. It clearly is. We said is wasn't the *best* stunt engine, starting in about 1988. That was enough to elicit death threats, apparently.

Any correlation between that controversy, and the stack of $400 modified ST60s sitting on a shelf, gathering dust, and mostly unsellable in late 1993, is of course strictly coincidental.
