The Eifflaenders really got it right with their .40 IMO.

On larger props it may give the Irvine .40 a run for it's money.

I put my PAW .40 R/C on a Acculab VI-600 digital scale. 394.4 grams.
Mark II Irvine .40 R/C diesel came in at 473.6 grams with muffler.
Earlier version of the Irvine .40 R/C diesel with muffler 474.7 grams.

Irvine engines are not famous for their low weight but for their high power and revving ability....

ON THE IRVINE THING I have an Irvine 36 its a conventional 1 pc case with a backplate same mounting as the irvine 25 MRK lll almost the size of the 40 It does have a diesel head
made by AJC, runs well, not in a plane yet but cannot really see the advantage compared to the 40, Maybe as a glow Irvine wanted an engine with more power that would fit a 25 mount

no lightweight 353Gm with muffler

my OS32MAXFX Davis head pitts muffler and mount about 380Gm and quite sure it will run circles around its ready to go in a KMP beaver electric conversion almost finished

martin

MY 46SXMAX OS Davis head will be in the ultra stick

Another Irvine .40 question...

First of all, I got the instructions through the mail and I was very glad to get them.

I attempted to remove the head from the Irvine .40. First I found that I could unscrew the T-bar easily so I took that out. I looked for the set screw that is supposed to be in the side of the head but that is missing.I removed the six bolts that hold the head and lifted it off the case. I was surprised when the cylinder came out with it. So far, I've not been able to get the two apart and I'm not sure how to do this without damaging the parts. Advice desired. John

Propane torch for 2 ~ 3 seconds round the circumference of the head. Using welders gloves, seperate the peices.

I got the head and cylinder separated. I coated the cylinder with oil then put water in it and froze it so it had a plug of ice in it. Then I used a pencil torch to heat the head and they came apart. Thank you all for the good advice. John

Well to keep the count up I also have the Irvine 40 D. Used it to power a 40 size pattern plane in the early 90s. Not particularly powerful but worked well enough. Used an 11/7 prop. Don't remember the rpm. It was fun to start when the temps were below freezing and the snow flying. I flew it a couple of times while the snow was falling just to say I had done it.

Hobbsy,

I have an old Irvine 40 Glow that looks similar to these pictures but different head (2-piece case). I also have it installed in a Sig Rascal 40 and it runs beautifully. I don't have any knowledge of converting a glow to diesel, but I would like to consider it if it is not too much trouble. I like the numbers you mentioned regarding your setup. Have you had a chance to compare the glow to diesel Irvine 40? How is power and throttle response (I know torque is better with diesel)? I suppose the fuel tank/tubing have to change. Do you mix your own fuel, or is it available commercially?

My first engine ever was a Davies-Charlton Spitfire I bought way back in 1974 as a kid for a control line. Nice engine, but didn't use it much before moving on to Cox 049's and more readily available glow fuel. My mother would not have approved of my mixing diesel fuel at home and it was not easily obtainable where I used to live.

Thanks,

hsukaria

HS, you have the engine on the left, the one in the rear is a Q-72, the red headed one is a Q-40. The Q-40 has a .030 inch smaller bore bore than the .40 you have. The Q-40 and Diesel have the same stroke as the .46. The standard .40 would make a good conversion. I use only Davis fuel which is readily available from Davis Diesel Developement and from Tower. I think Omni used to carry it as well if they're still in business.

Yep, Omni still has the Davis ABC mix listed.

Thanks,

I will look into it. I also have a Norvel AX-40 with a cylinder head that seems to be easy to convert because it has a screw in cap on the top for holding a glow plug. It seems that it would be easy to replace that one piece with a diesel head.

I will check out Davis Diesel.

Hobbsy maybe a typo the Q 40 takes the diesel head either the Irvine factory or Davis conversion not the regular 40 regards martin

Hobbsy,

My Irvine 40 looks like the left one in the picture as you mentioned. But it has the black Jetstream carb as shown in the Q-40. Mine also has the older muffler with the tapered rear (which is louder than present-day mufflers). That Jetstream carb is awesome!!!

OK, the carb from the Silver .40 is on my PAW .60, that carb is an MVVS 7mm carb, another very good carb. I have several I bought from Dar.

I lucked out and got a brand new head for my Irvine .40 diesel.  But, as I reassembled the top of the engine I noticed that the cylinder was binding on the piston and the piston was "catching" on the port holes in the cylinder.  I added air tool oil but the binding was still there.  This was not true before I pulled the cylinder out.  I must have deformed the cylinder somewhat when I was removing the old head.    What kind of repair (if any) can one doe in a situation like this.  I have contacted Just Engines in England and they said they had no replacement parts for the Irvine diesel due to it being out of production so long.  So, apparently I can't just replace cylinder and piston combination easily.  Any advice?

How would you have been able to deform the cylinder..?

If you would actually have deformed the cylinder I don't think you would even get the piston back in there. Is the piston in the same orientation as before?
You might also be catching slightly onto the backplate or something else rather than the ports.
If it turns over ok but just doesn't feel exactly right, then give it gentle run in and hope for the best...
