So do I understand that the OS LA-S 46 and 25 are out of production now?
Is OS making new CL engines?

I hope not, that would suck.

The parts to convert the RC engines are readily available. They are—
FP 20/25 Venturi LXCW99 9.49 22312000
FP 40 Venturi LXCX05 11.99 23312000
NVA 20-25FP-S LXCR49 13.49 22311000
If you want to retain the rear needle set up, you do not need the NVA 20-25FP-S but instead, you get Nozzle 20-40FPS RN LXMU30 6.29 21381980.
These numbers are— Tower stock number, price from Tower, and OS Part number.

Just saying...no engines listed on Tower site now...

Somehow I get the impression that Tower Hobbies is a high volume marketeer. When sales diminish although they are there, when they drop below a certain limit they discontinue the item. Over time I've seen a number of items discontinued, which tends to lead me to believe that is the case, although I could be wrong.
One engine that was dropped early on was the Thunder Tiger GP-18 some time back. I was surprised to see it dropped so quickly. It seemed to have no vices, but I gather that sales weren't sparkling, hence the drop.
Actually its been the climbing prices of new engines that have been a disincentive for me to purchase from Tower. I suppose that inflation has taken its toll, but even when I didn't have as good of salary, things seemed more affordable then. Most of the engines I have obtained as of late are used.

The 46LA parts listing says the engine is discontinued so parts may not be available and it's listed in the discontinued engines list:
http://www.osengines.com/parts/discontinued.html
It's my understanding the line is discontinued per the notices on various dealer websites. A retail store wouldn't list an engine as discontinued based on their decision to no longer stock it.

I would say that is a more definitive answer. The engine is listed both as current and old. Most current engines are not listed in both places if you look through the two pages.

It seems everywhere I look, the 25/46 are discontinued. You can't buy them anywhere. This says to me that OS has discontinued the engines ... and not the outlets such as Tower/etc because of poor sales.

Hobby King has the LA 25's in stock. .

I'm lead to believe, and read actually, that there's absolutely no difference between the OS LA offered for CL or the OS LA offered for R/C.
Tower will sell the R/C to CL modelers AND the venturi also, not to mention a NVA, if Tower sells NVA?
Could be just marketing. Do the $ math.
While we're on it, what NVA are guys using for the OS LA .46 without having to drill the case?
-
The RC version ....
Tower even lists the 25 la RC as available early april
LA-S's I can't find anywhere
-
Yeah, maybe thats what they'll do with the RC version ... add a venturi and sprinkler to the box ... covers both worlds.

You don't need to drill the case, the case is already properly machined for a venturi. There is also a nozzle that can be used with the rear NVA. The LA25 is the same setup, same nozzle even, but different venturi.
The 25 has a front needle available, I don't see why it won't work with the larger engine, probably wrong hole size.
All my OS engines are converted from RC. I need parts to convert the last couple while they are still available.

I doubt it, "unnecessary" extra expense. Hopefully they will keep those parts available and stocked though.

That NVA (22311000) fits all of them from the LA 46 on down. As well as any other engine that has the same width venture. y1
And they work great AFAIC! ;D

Charles was referring to the needle bore. Some alternate needles require drilling.
Your statements on the LA25 needle/nozzle contradict each other. O.S. #22311000 needle will fit FP20-LA46
-
are you looking for an engine?
Or complaining about the lack of engines?
OS 46, and 25 are all over the place you can get them.
There is enough out there for all of our lifespans.
Either new or slightly used as RC'ers flock to electric.

I was making a statement that engines for CL are not plentiful if you want new mfg.
But you knew that.
You also know about eBay.
My point is that CL is not sustaining the market.
I own nine of the LA-S engines.
I own 10 Fox .35 Stunt engines...etc etc.
Point is about the market.
Glad Enya still makes engines and glad RSM and Brodak make kits.

Two of the best engines ever made for stunt were RC, one, RC-only (never had a CL version) -ST46 and 40VF. The LA-S and FP-S are simple to convert, as are any of the similar engines. As soon as people figured out how to tame schneurle engines (by adding a pipe - not by grinding on it!), the engine problem in the mid-80's just went away.
It's very nice to have been able to get a motor that works perfectly straight out of the box, but as long as we can manage to control ourselves to reasonable aftermarket solutions (as opposed to Dremel tools and stacks of head gaskets), it's at most a slight inconvenience.

Gee Dave,
I could use one of those Fox .35 stunt engines. #^

I still need more info on the NVA? I need a few. Fit vintage 35 McCoys?
Where and what to buy? Tower? Someone associated with the Forum is better?

If you are in the market for a LA46 check out Kaz Minato site. He has 25 of the LA46 s.

The ST/40 and 46 were both sold in CL versions. They came with the sprinkler style venturi. I still have both of mine from 1969. They were the thin sleeve version and double rings. The first 46 RC version was a hacked of venturi with a carb mounted. I have one of those also. Later they mounted the rc carb on the CL version. CL came first. %^@

Hi all, I ordered two os 25 needle valve assemblies, standard, not the backplate version from Tower 3 weeks ago and was placed on back order. They just arrived the other day. So i'm thinking parts will still be available for awhile. I don't know whats going to happen their supply runs out so I would say stock up now for the future.

I know that, but they were not designed for CL specifically, they were converted RC engines.

Check RC JAPAN they have NVA for about 6 bucks plus shipping in stock.

You missed the point. The CL came first. The first ST/46 RC motors had the venturi cut off and a carb added to it. Later they converted the CL motors to RC by adding the carb on top of the tall venturi.
Ok I will take some pictures of the very first ST/46 RC so you can see it is a converted CL motor.

Jay,
Have you bought some parts from RC Japan? What do they charge for shipping and what is there delivery time? Thanks for the help.

Hi Dennis
Yes I have ordered from RC JAPAN several times. Their venture and NVA prices can't be beat. Shipping is not that bad, but it does help if you and say a few of your buddies order together. That's what I do. They will order any parts you need as well.

Back in the 1970's I was doing a lot of work with the ST/46 and people started to send them to me to custom rebuild. I started to see these with the cut off venturi and it looked like someones hack job. But I was getting them even from Europe. At that time I was buying parts from Italy direct. I took a picture of one of these motors and sent it with my order. They told me they took The CL motor and cut off the venturi and glued on the carb. Later they found that the carb cold be mounted on top of the venturi but it put it the carb very high and some did not like it so they did another big batch that sold only in Europe. I have seen ST51's and 56's also done this way. I have never seen a .35 or .60 with a cut off venturi. Weight 8.2 ounces. Picture was taken today.
Here is one of mine from that I ran in the 1980's It did not have the hole for the needle valve,I drilled the case. This is a very highly modified motor with a hemi and shaved head and dropped sleeve. It is a lot more powerfull than a stock .46. I have not built any of these motors since 1992. A stock motor with the ABC conversion is a turn key operation.
