Status: offline 		Hi all,

I have been lurking around reading as many posts as I can find regarding the Ziroli P-47. I am planning the 92" as an upcoming build, and was just wondering if anyone had any thoughts, comments, pictures, etc. they would like to share about the larger version specifically.

Also, it seems as if they 70" model is much more popular (at least based on discussion threads here) than the larger 92" model. Do you suppose that is just due to the reduced cost, quicker build, easier transportation, etc. related to the smaller version, or is there something about the large one that people steer away from, other than the obvious things listed above?

Thanks for your help!

Status: offline 		The 92'' p-47's are some of the best/easiest flying models you can fly! They have no bad tendencies at all.They fly like a giant trainer,the reason you don't find too much on them at/on this board is because 95% of the time people write here to ask for questions or sell something.You probably won't find too much info because they are awesome flyers and no one has anything bad to say!!!!! The larger one's fly better than the smaller ones and look much nicer too.Atleast I think so.Go with the larger one,you'll be glad you did.follow the link and you'll see a pic of mine

Thanks for the response. That is a gorgeous plane! I am not familiar with the scheme you chose - where is it from?

This will be my first truly "large scale" plane, so I am glad to here that it is a solid performer and has good characteristics. Any special challenges you ran into during the building process? Also, if you can provide any specifics as to your setup (ie engine used, retracts, etc), that would be great! I am planning on the G62 per the plans, but am open for input.

Thanks again for your help!

Status: offline 		I'm using a 3W 75 twin spark this year rated at 8 horse power. Last year I flew it on a 3W 70 rear induction carb rated at 6.5 horse and it flew wonderful.The only reason I changed motors is that I need a 70 for my Yak-3 so I pulled the motor from my jug for that plane.I then ordered the 75 twin spark just to see how the motor performs and I will put it in my jug for this year.
The plane weighs in at 35 pounds.The retracts are Century Jet but don't buy them as they are junk!!! If you can afford them go with Sierra Precision retracts,if not just use the Robart as the plane is cut for them and they work alot better.
The paint scheme is from the "Checkertail Clan" punch that name in and you'll get ALOT of pics and sites.I actually found this particular model in a hobby store in Detroit and decided to do that scheme.
Squadron publications has a great book on pics of this fighter group from p-47,p-51,p-40 plus a few captured german planes.I took the 3 views from the model kit and used them for panel lines and rivet detail.
If you have anymore questions feel free to e-mail me direct

I love my Ziroli 92" P47! It's probably the best warbird I've had. Very solid in the air, impressive, and lands surprisingly easy, almost like a trainer. You'll need a big vehicle to haul it around. I used Ziroli's glass fuse for this one and, being my first experience with a glass fuse, I'm very happy with it. It saved a lot of fuse planking time. Mine came in at 28# and I'm using a G62 in it and Robarts.

fryfly,
Beautiful job on your "jug". I agree with you about the CJMs. They suck! I had them in a couple of warbirds before and I ended up replacing them with Robarts.

Status: offline 		JBeck....."Z" P-47 one of the best Warbirds around .....long fuse and wide gear make a good combo......I have not found one bad thing about it.....I also have the 'glass fuse with the "N" model wing which makes it a 96" WS.....Use a Q-75 for power.......Tmoth4...How did you get 28 lbs...thats very-very light ....Mines over 35 lbs but I build heavy usually......Bill....

I used Sig AAA balsa and used the lightest wood in the tail. Wings and tail surfaces were glassed with 1oz. cloth. With the G62 and my homemade muffler system no ballast was needed in the nose.

All things being equal.....bigger is better.

They are both the same plane (design-wise) but the larger the plane-the more stable it is in the air. Also the 70" is not large enough to be IMAA legal (if that's your thing).

The reason (I think) that the 70" plane seems to have more threads is that the cost of building the smaller plane is less, and the design has been around for several years longer than the 92" plan.

Status: offline 		I am currently building the 70" Ziroli P-47. I am spraying the final color on the aircraft and hope to fly it in the spring when weather is better. My P-47 has flaps, two aileron servos, Robart Retracts and a G-38 Gas Engine. I would have to agree that bigger will fly better. It always has in my book. I feel that my total weight will be about 16 pounds, not a light bird. I understand that it will fly great at this weight, but wing loading seems high. At least high compared to an IMAC or pattern ship. I flew a Bob Violett Models Maverick Jet a few years ago and its wing loading was close to the P-47. The reason I went with the smaller P-47 was cost, transportation and less time to complete the project.

I TOO HAVE BUILT THE 70IN P-47. MINE CAME OUT AT 16POUNDS. I USE A SAITO 1.80 ON IT FOR POWER. ALL I CAN SAY IS IT IS ONE FANTASTIC FLYING AIRPLANE. TRACKS WELL ON THEGROUND, ROCK SOLID IN THE AIR, AND LANDS ALMOST LIKE A TRAINER WITH THE FLAPS DOWN. THE SAITO 1.80 IS PLENTY OF POWER FOR THIS AIRPLANE. MINE BALANCED RIGHT ON THE MONEY WITHOUT HAVING TO ADD ANY WEIGHT. SO DNT WORRY ABOUT THE WING LOADING. YOU SHOULD BE PLEASENTLY SUPRISED AS I WAS.ABOUT 30 FLIGHTS ON MINE AND IT IS ONE OF MY FAVORITES

What size fuel tank did you use for the saito 180? I'm putting one in byron corsair in a few months. I've been told the saito 180 is real guzzler. Was recommended to put in a 24oz tank.

I PUT A 24 OUNCE IN MINE. FIT WITH PLENTY OF ROOM TO SPARE. THE SAITO 1.80 WILL USE ABOUT 1.5 OUNCES PER MINUTE AT FULL THROTTLE WHEN TUNED RIGHT. SO THE 24 OUNCE TANK DOES GIVE IT PLENTY OF FLYING TIME.

Status: offline 		Bigger is better... Have you looked at the Meister Scale P-47.
It has a 103" w/s and is a two piece wing. It is a really fast building plane. I am currently building 3 myself. I have the fuses finished or I could have sent you construction pic's . They frame out really fast, you are sheeting 3" at a time.. Plenty of room inside to add anything you want and they are great fliers..
Check out Meister's website and see their pic's:
