Hello All,

I am fairly new to this forum, been reading a lot for the last couple of months.

I am building the 92" Ziroli P-47, using a Precision Cut Kits kit. Going for the Razorback variant.

Here are some first pics, starting with the crutch

Hi David,

It looks great so far! I am going to be starting on the Ziroli 92" P47 this winter (we just purchased a new home, and we move in in January - I know, bad time to move, but at least I get more building space!

I was also planning on going with the PKC kit, although I am torn between the built up fuse and the FG fuse that Ziroli offers. Any particular reason (other than the cost) that you decided to go with the built up fuse instead of glass?

This will be my first warbird project, and 2nd large scale project. Any comments on construction techniques yet? I am hoping it will be pretty straightforward. I have never built just from plans, but they seem pretty clear and the "directions" that came with the plans also seem pretty useable. Overall, I am really happy with Ziroli so far, both in terms of dealing with and answering questions as well as the quality of the product.

Best of luck with your plane, and keep us posted of how it goes!

-John

The Ziroli P47 makes a great looking/flying bird. What are you going to power it with? Glad your going with the razorback, there aren't enough of them around IMO.

David:

Looks great. I built the 60 sized Top Flite kit (razorback) last year and the Yelow Aircraft (razorback) this year. I am thinking of building the Ziroli next year. I have to build a Jerry Bates Hellcat and a Vailly Tempest first. I love the P-47 for its looks and the way it flies. Keep us posted on your progress and good luck with the building.

Here's a 70 inch Ziroli I'm doing for a customer. Said customer has expressed interest in having me do the big one next except using the glass fuse. I've really enjoyed this one so far. Keep the updates coming David, nice project.

Hello All,

Thanks for all the input. I will answer several of the questions and add some more detail.

I chose the wood fuselage so I can build the airplane again from the plans, if I want. Plus, with the kit, it is pretty easy to build, vs. having to cut out all the parts. Finally, I believe it is actually cheaper.

The all wood kit is $350 and the wood supplement to the fiberglass fuselage is $300. The Fiberglass fuselage and belly pan is like $300, so you can cover a lot of the cost of the robart retracts by doing an all wood version.

I selected the mundane G-62, per the plans and recommendations from a variety of sources, including Tmoth4, a member of this forum and builder/flyer of a glass version of the big ziroli jug. Also, I can get good support from my local hobby shop on the Zenoah.

All this said, I have been thinking about building this airplane for many years. I really like the Zirolis that I have seen, and with the laser cut kit, it just made sense for me.

I have some other pictures getting developed. I will scan them in as they come available.

Just a few comments on the laser kit. The overall quality of all the wood is quite good. The laser cutting is very nice. Three formers were correct on the outside dimensions, but had to much wood cut out on the inside and the notches for the crutch. I was alarmed at first, as I thought I had somehow narrowed the crutch to early, (though it was built over the plans). As it turns out, I slid F-6 on first, and it was one of the three cut wrong. I center it, along with, I believe, F-10b, using stringers. I then shimed and glued them in place.

The folks at PKC stated the parts were only as accurate as the plans. I felt like, for the money, they could have easily corrected any such plan problems. In my urgency to build, I never actually laid the formers on the plans to see if that was the problem or not.

I found also that SS-1, the stab saddles were missing. I hunted thru the kit and never found them. I scoured the plans, and found that SS-1 was not anywhere except in the overall side picture of the fuselage. It was no where to be found on the several sheets that pictured formers, ribs, and wing saddles, etc.

With the plan error, I can see how PKC may have missed these parts. In fairness, I have not called them, I just made the parts and went on.

Overall, with the reduction of time that these kits give you, I would say they are worth the money. Cost out the wood at the local hobby shop, add in the labor and they seem reasonably priced.

Just a follow up on PKC. I did call to provide feedback. PKC was quite receptive and said they would look into it. The owner said that most folks never took the time to call back.

Anyway, good folks to work with imho.

chad,

Thanks for the picture of the 70" in the buff. One of the areas I am giving close attention to is sheeting the razorback area of the fuse. The stock that Ziroli calls for is 1/8" and there is a compound curve going from the main formers to the razor and then over the top. It also tapers and changes to more of the "razor" as it moves aft of the canopy. Great fun.

David, I actually cut off the top of the formers for the razorback enough that I could cap the top of the fuse with a solid piece of 1/4 balsa. This seemed easier to shape than trying to force the sheeting around the rather tight curve. Also, if you sheet this area with soft balsa it pays divedends later when trying to blend all the sheeting together.

I'm building the 70" version too, except in bubble top form. Interesting to see the 90 incher under construction as I can see that it's identical to the smaller one.
I took a long break from mine to build some other stuff but I have the correct struts coming from Robart as I type this and hope to start back up on it this weekend. I have a few construction photos on my webpages.

That's looking good Chad. Send me some photos of the flap/aileron areas if you have any. I'm probably going to cut mine out this weekend.

David, keep this thread going as I'd love to follow your progress on this project.
