P40 ZDZ option
Did you guys compare to any ZDZ engines? I was asking about a ZDZ in a Ziroli AT6 in another post....This might be a good thing to have people list their airplanes and new engine selections. bob

3w 60? P-40
Mine has a ZDZ80 in it and I use a mejlik 24-10 3-bladed prop.....
What can I say, it flys as a fighter warbird should....Fast, with power to spare....
I was able to fit the engine without ant holes in the cowl whatsover....

Warbird_1....
Is that a Ziroli? I had a G62 on one I owned previously, and have observed a few similarly powered at warbird meets and they seem a bit lethargic with a G62......
A 50cc would certainly be on the "fringe" for a Ziroli P40...
If yours is a Ziroli, can I ask what it weighs?
Mine weighs near 28lbs, maybe a little more as best I can weigh it.
BTW, I like the ZDZ80 (single) so much in this airplane, as well as the fit in the cowl, I bought anther to use on a Ziroli Mustang....
This engine is light weight, has similar dimensions to a 60cc equivalent, and has the added feature of a rear mounted carb, ideal for warbirds.
It's relatively easy to fit this engine in the cowling of some warbirds as there's no holes required for a side mounted carb....

P-40
branded, my p-40 weighted in at 26 lbs. i certainly couldn't do huge loops with mine but it did fly ok with the 50 in her. i always wished i had more power though, ron oh..... btw i looked at the zdz line. they look like a nice engine but i stayed away from them simply because of all the extra parts runnnig at high rpm's. i saw distant problems down the road. i believe ,the simpler the better. i went the the 3w line because they don't use chainsaw parts in a machined case . there cylinders are designed for model airplanes and with the reed valves, they made great torque ! i have a 3w-50i on my yellow spitfire and that flys at 109 with a 22x10 prop that prop is to small plus it's not even broken in yet , ron
BTW. IF YOU CHECK THE HP RATINGS BETWEEN THE G-62 AND THE QUADRA 50 , YOU WON'T SEE TO MUCH DIFFERENCE. I HAD A 20X10 ON MY 50 I THINK

3w 60? P-40
22X10 IS OK FOR BREAK-IN BUT YOU SHOULD JUMP TO A 22X12 OR LIKE A 24X8 MAYBE . THEY SAY TO USE LAWNBOY 2 CYCLE OIL FOR THE FIRST 4-5 GALS JUST TO BREAK IT IN FASTER THEN GO TO LIKE HONDA HP2 FULL SYN. OIL. I HOPE THIS HELPS. IF YOU HAVE ANY ??? GIVE CACTUS AVIATION A CALL. THEM FOLKS ARE REALLY NICE TO WORK WITH. I'M GOING FORWARD ON BUYING THE 3W-75i FROM THEM NEXT WEEK , RON

I'm busily installing a Zenoah GT80 w/CH in a Ziroli Corsair at this time. I had a Corsair with a Sachs 4.2 and it did well, but I always hated the huge hole in the cowl for the carb and muffler, not to mention the fact that the engine was offset off center to fit such that i could not use a dummy radial....
The point I suppose I'm trying to make is that there's alot more to selection of an engine for a Warbird than meets the eye....I find that the biggest "turn off" to a gasser in my selection process is whether or not the plugs stick straight out of the head, or not. I get real tired of trying to fit engines in tight cowls because of plugs that are installed 90 degrees to the top of the head.
The ZDZ Single I find makes a good fit in many such designs that would ordinarily be fitted with a G62, Q75, etc.

3W 75i
Warbird 1, I'm also putting a 3W75i in a Ziroli P40. When I spoke with Nick Z about the 3W, he said it would be a good choice, just might have to cant it a little to clear the muffler.He's using a 3W 80 in his,sure enough !when I mounted mine it had to be canted a couple of degrees to clear. I used a supersonic muffler from Aircraft International.I also spoke with Gerhart there and he stated that the 75i would swing a 24x10 3 blade, although it would not have the quick throttle response the 2 blade would have. Scale diameter is around 27"and with a 24" blade it will be hard to tell from scale size. Right now the glass fuse has the engine mounted, all formers installed and tail feathers completed. I made the wing out of foam and its ready for ailerons and flaps. I used Robart retracts. The way it sits right now its at 24 lbs, I'm hoping to keep it under 30lbs hopefully around 28lbs but I think that is a little unrealistic. Keep us posted on your progress, maybe we could swap ideas. Luck Jim G

3w 60? P-40
hey ,ray long time no see how's it going?? nice warhawk!
i have decided to go with the 3w-75i for power. i'm not looking to 3d the bird ,but i like the extra kick in the pants for power climbs after straffing the japs airfields and hangers heheheeh i had a ziroli a few years ago and while CDing the glenn curtiss model meet i flew my p-40 over GLENNS resting spot in a modest cemetary 100 yards from the runway which we were using . alot of cool history in the queit valley. everyone should visit at least once. thanks for all the info , ron "warbird_1

3W-80
I have a 3W-80 inline twin in my P-40. It has live exhaust on both sides. The engine is a little rich on idle so it blows smoke out of the exhaust while taxiing. Nick Jr. has this set up in his also. I fly with a 24x10 Menz prop at 6000 feet in Denver and 24X12 at sealevel. It is a wonderful plane.

P40
Well it took awhile but I finally got my ZP40 in the air. This shot is on the bench about a week ago. I got to fly it Monday. The 3w 75i is a great combo. Nice big loops and plenty of power. No tendency to snap out. Engine is still running rich, 5680 rpm with a 24x10 Mesjlik. Came in at 34 lbs, can't wait for the engine to turn on better. Looking for info on what rpms I should be looking at with this engine. When this engine breaks in , it will probabley be up around 5800 5900 rpms . Is this a little too high, should I be looking at more prop or what. Hope the shots got thru. Jim G
