Irvine Red Case Engines

Anybody using any of these? I have just about all of them currently available in my collection. Cannot recall seeing anyone using one in SN mag or here on the forum. Must be a good reason.

Bill, I am using a RED Irvine 46, reworked by Byron Barker, in a 640 sq in stunter. The engine run is classic 4/2/4, with no bad habits. This one runs like a nice ST 46, NO LIE! Friendly with plugs, props, and fuel...too bad the Irvine's are fairly $$$! We do, however, get considerably more "grunt" out of the reworked Magnum 52's, that Byron as well as our host Leonard sell.

What did you have done to it and what did it cost?

I used an Irvine 40 RLS engine for a couple of years with a Randy Smith CF pipe and really liked it. Irvines are very well made and mine gave me absolutely no trouble at all. The 40 RLS is a piped stunt motor, so I didn't ahve to do anything to it. A very good motor.

Not exactly what I would call a massive responce on this one!

I've got the 40RLS as well but with an Eather pipe. I found it to be extremely touchy as far as priming goes, the slightest bit too much and it'd take your finger off. Other than that it was magnificent, more powerful than my 40VF and dead easy to set up on the pipe. Once, just for a laugh, I tried it with my usual 12x5 Zinger and it still pulled the model around with ease (WAY off the pipe of course). My particular engine was the one used by Derek Pickard for a review in the June '96 Aeromodeller magazine.

Yeah, Your right Bill kinda quiet. I don't even know anyone who owns one either RC or CL. Maybe there just not popular around here. They look really nice and everything I've read was good in the RC mags. But nary a word in the control line world.

Greg, I hear ya on this one. It surprises me too. I have 9 different Irvine U/C engines here. Not all with the red case but all are very well made. A little heavy but when I hear people say they had to add nose weight that shouldn't be a problem. The only problem I have had with any of them is taking them out of their box and starting them. Can't seem to do it. Such are us engine collectors! Same problem with all the kits I have.

Lets see, I have 2 each of the 25, 40 46,53, red case Irvine
Two of the controlline version Irvine 36 motors one is brand new the other has been run in my Twister and is absolutely too much motor for it. It needs a larger prop then I can fit on this plane and a way to slow it down a little. It pulls like a freight train.
Have 2 old style 40's, <3> 40 diesels, had Len make a venturi up to my specs for one and it is a great stunt motor for a special plane that I built, 2 -20 diesels both NIB , one 25 old style 25, one old style 46, one old style 61 and 120 and 150. Oh I also have the mills/Irvine .08 and 1.3cc repros.
So do I qualify as having a few Irvine motors.
Incidentally I have venturis for most of the sane motors for C/L unless Dan Banjok wants to try and fly an Irvine 150 on a Flite Streak. Then I'd have to really work to accomodate him.
Incidentally the bore for a venturi is different from the old style case to the new red case motors. You need to sleeve the red case to get an old style carb or venturi into it. No matter what your conceptions about these motors make no mistake, these are the best motors that Great britan has made in a long while. This of course is a mass produced motor.
For comparison the Rustler/ Merco Motors define the best that private industry in england has ever made. You should really take a look at all of Ians offerings.
