40/46VF - still the gold standard.

I guess that makes the Irvine 40RLS the platinum standard then , it's a sweetheart of an engine. And yes, I have the 40/46VF's as well. As for the Stass's 42RE, I'm actually quite impressed by it, even with its plain bearing crank and iron piston, although I'm beginning to think I've got the only one in the world because no-one seems to know anything at all about it.

Someone forgot Rossi and OPS

:-)

Randy

No, not really (check my last post!)

Would I be too much of a smart a** if I were to point out that a muffler on a Cox 049 would...

Oh, never mind.

Surely there must be some more rear exhaust engines out there?

How about the Enya 21 CLX, OS Max 46 VX, OS Max 21/25 XZ, Picco 21/45/90R (in fact the entire Picco range), and the best for last - the stunt Cyclon 60!

If you look around, you could find one of the fine Fox rear exhaust 36 with the can muffler!

At the time of the 40/46VF there was the Enya 45CXL, AAC construction, lighter then the VFs and with 144 exhaust timing. Unbelievably, seems no one has used this engine in C/L. Perhaps some in Downunder or Japan may have used one, who knows?

   I recall someone trying it, but I can't recall the results. Enya doesn't have much of a rep in US stunt circles, and when you have an essentially perfect VF setup, and then PA and RO-Jetts, not a lot of motivation to go way off the reservation.

Whats the deal with the VF nowdays. Does OS still make them. If I am not mistaken, that was an "adapted" ducted fan setup that hit the big time in f2B.

Here's an older RE Supertiger.

Yes, believe it or not, I'm considering strapping it on to something. Undecided?

   I think there were originally intended for small pattern airplanes. There were ducted fan versions of them but I think they were modified from the pattern version, not the other way around.

    They haven't been made for at least 20 years and it may be bordering on 25. The reason we (well, I) still discuss them is that they are still widely available, and in many ways they are the standard by which the others are judged. We are still designing to the same standards - David's current airplane is for all intents and purposes is indistinguishable from an early 90's classic West coast 40VF plane. Keep it in the 60 oz range with a 40VF and you are giving up NOTHING as far as flight performance goes. In about 5 minutes there will be a bunch of people saying how stupid I am for saying that, but none of those people have managed to beat Paul Walker and his Impact/40VF , either. I may have lost track of it, but I think the *exact same airplane* won the 1990 and 2005 NATs. So we haven't managed to do any better over around 2 decades of trying.

    I like the particular version and setup of the RO-Jett 61 entirely and precisely because *it runs like a gigantic 40VF*. In fact as soon as the Sun came out at this years TTs I wish I had brought a 40VF with me. At least I would have remembered how to set the needle, which is better than I managed with the 61 this time around!

This cat is still current -Not happenin?

   It's not the same. No one has bothered trying any of the newer-era OS engines, that I am aware of, since we all have PAs or RO-Jetts, with drawers and drawers of 40/46VFs rusting away if necessary. It may work but no one knows, and given that it would likely take roughly a year on average to work out a good setup for any new engine which may well turn out to be a waste, not a lot of motivation.

   Everybody wants to fly electrics next anyway.

This is going to be famous L

Hold up, not "everybody".......

Derek

I am with Derek on this one! I like cranky, dirty, IC engines. They are the main reason that I fly. If I had to fly electric, then I would give up. I am never going to win any competitions because I don't enter them. I am sure that there are many sports flyers that think the same way!

Andrew.

You know it was derek!
 

I like a smoke trail!

In all this rhetoric did I miss the OS .25 VF? Even Randy didn't mention it...For shame!

And for all those "newbes", it was the OPS .40 that started all this insanity!

What do you do with a VF 25?

Hi Steve,

You put it in a Stunter of about 50" span, with a pipe.  One has been published in FM (Eliminator) and planes like the Ares/Perroquet/Gieseke Nobler go extremely well with the .25VF piped set up.

From where, or who, are Stalker RE engines available now?  I heard a model builder in Canada was supplying them to the US for a while on special order.

I get my Stalker engines from Kaz - However I only use them for Classic now.


Derek : Tisk tisk...   

I have quite a few RE engines (Irvines, OS, Stalker, Stass's, Taipan) but my latest is this Torpedo Special "Twin Stack" from the late 40's.

The Irvine 61 is brand new and uses a Dykes ring, later versions were ABC and I think had a red head. The Irvine 40RLS uses a stunt timed liner and the red head to distinguish it from the normal RC version. AFAIK mine is the only one in Australia and it's the one used by Derek Pickard in a report he did for Aeromodeller magazine on piped engines for CL stunt. The SE exhaust Stass's is relatively common (they're listed on the Carlson site) but the RE version seems to be extremely rare, no amount of Googling finds any mention of them and I've asked on every forum but no-one has heard of them. I still have one lead to follow up on though. Note that the name is actually Stass's as can be seen on the crankcase. Apparently the RE was made for CL use only. One photo shows it with its exhaust stub in place.

Hi Brian,

Thanks for the nice pictures. The Irvine engines looks very interesting.

Martin

 I have purchased 2 Stalkers from Alan. Quick turn around .. nice guy.
