Do you mean piston and sleeve? With con rod? With wrist pin?

Thanks Randy, Jerry

Hi Tom   you have on order a  46VF   ABC on order which I have now in stock, did you want to  add  a  40 VF  AAC  PS ?

Randy

[Brett Buck]

I still want two.

What would it take to get one of these into an LA 46 case?

The VF is a rear exhaust engine.  Nothing would line up with anything in the side exhaust LA case!

So I would guess the answer to your question would be a VF Case and crank etc.!

[tom_weedman]

Randy I will take a set for the VF 40. And let me know how much I owe you for the 46 VF set and will put it on my card
Thanks Tom weedman

[Gerald Arana]

Randy,

Put me down for a set.

Thank you, Jerry

What would it take to get one of these into an LA 46 case?

I do not know if that would be wise, you maybe would have to machine down the outside of the sleeve or the inside of the case, match up the port height, you will then have a smaller engine, you would need, or want to find a pin  with pads on the end, a better  solution would be to get a  true  ABC  from Brian,
The OS LA sleeve  is  very thin, if I did this and did not  get a sleeve piston set from Brian, I would use  a  46 P/S set instead of a 40

[Brett Buck]

What would it take to get one of these into an LA 46 case?

   How is that better than a stock 40VF?  You would have to use a side/rear header and a bunch of machining to at best accomplish nothing better than a stock engine, with an irrelevant reduction in the weight. An it not run the same as a VF- not likely better, very likely worse.

     Brett

[Brett Buck]

What's a 40VF weigh?

   It weighs about 12 ounces with the venturi and spraybar, the same weight it was in 1990. And 91. And 92. And 93. And 98. And 05.  With the AAC it will be more like 10.5 or 11. This on an airplane that weighs *4 lbs*.

     Brett

[Randy Cuberly]

They're both loop scavenged, it doesn't matter where the exhaust comes out.

It matters a lot if the openings (ports) in the sleeve don't match up even close with the openings in the case.

If you don't believe me just buy one and try it!

I once put a Rossi C21 piston and sleeve into a Fox 19 and called it the Rossafox. I put a K&B P/L in a Fox 35 and called it the Fox 4011. I have port matching skills. 

If the person making these is who I think it is I'd like to use it for something. Been combing the web a bit and can't find an OS VF 40.

In addition to the many currently rusting away in various sock drawers, and the one I sent to Phil Granderson that go lost in the mail:

   https://www.ebay.com/itm/model-airplane-engines-O-S-MAX-40-VF-ABC-NEVER-used-in-box-with-papers/272933796120?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

      I couldn't discourage you enough to not do it, but if you are going to put it in a different case, I would select a case for an otherwise useless engine like a 40FP, Fox 40 compact, etc.

     BTW, the biggest issue is not getting the engine, it's finding acceptable propellors. I am down to my last Bolly 11.75-4.25, which is the one you want.

What’s wrong with using a APC 11.5x4?

Brett  it will not be an issue much longer, We are making the moulds  from 2 brand new Bollys  now,  so I will have them in stock  first of the year  or  late  DEC

     Outstanding, this will make  it a turn-key operation again.

What’s wrong with using a APC 11.5x4?

    Nothing, per se - I qualified at the 1994 Nationals using the original APC 11.5-4 narrow blade version.  However, the canonical system is Paul Walker's and you can try any of the others using the same prop, including going all the way back to the 1st-generation high-rev systems.

I have done tons of this, its a lot of fun, and many times you make a better motor, but I do not think so  when the  46 LA  is the subject,  Putting things like  ST 60  piston sleeves in a  COMO 40, and homemade  56 parts into a ST 35 case all made for  Great stunt engines, I have  a  ST 60 that is a 75, a OS 35S that is a 46, a OS  FSR 40 that is now a  56, , and a  shiney case  FOX  36 that has a  ST 46 piston sleeve in it.     But if you insist on trying the LA 46, I would  go for a  VF 46  P/S  setup, as they are  BOTH the  same  outside diameter.  But haven't checked, but I think even the  Vf 46  would make the  LA a smaller  bore, and smaller motor

I will take a set

Thanks

Thanks  John   I have you down for  1  set

[Ted Klein]

[Damian_Sheehy]

Randy,

Please put me down for one set.
I've been sitting on the (Electric) Fence with a 40VF sitting on the shelf.
Happy to hear about plans for pistons, props, pipes and planes in the works.


Thanks,

Hi Brett  best thing is not only will make turn key for  VF40, but the  prop  will also work very well  on most all 40 pipe engines, 46 LA  40 LA  ST 51  OS  VF 46 , PA 51 61  and many other  engines

Randy

[RandySmith]

Hi All

The Run has started, it will take a while and I will let you know when they are ready to ship, These of course will be the  Lighter  and  much tougher  AAC versions  just as the  PA engines are .
Anyone wanting to be added to the list please contact me

Regards
Randy
