RE: Ziroli DC-3
Just a few more pics of the fuse,I still have some detailing to do like the observation dome etc.I added the forward nose hatch to allow ballist to be added.I have a tray there to accomdate this.The fuse has picked up a few dents and scratches as time goes on just like the full size ones. Time to get on with the wing centre section.

Just got my dummy radials and static props from Wayne Siewert at Aerotech Models Inc.and I am impressed by the detail.Nice work.Its all cast resin parts.Can't wait to see em on the plane.

RE: Ziroli DC-3
Looking terrific, Steve. What's the chances of you bringing this puppy to Joe Nall next year? I'd love to see her in person, especially the FM finish.

RE: Ziroli DC-3
I'd love to go to the Joe Nall meet George,thanks for the complement.I'll plan on going to it,and if everything works out with the airplane I'll see you there.
I still haven't decided which method to use to apply all of those rivets.Has anyone hazard a guess on about how many rivets there are on a DC-3?I would guess around 30000 give or take a few thou.Any guesses?Somebody's gotta know..he he...
I just cannot vison putting that many rivets one at a time on this airplane,but hey maybe thats the only way to do it right...

RE: Ziroli DC-3
I was thinking of maybe:After I laydown all of my lines where I am going to lay my rivets.To use a properly spaced dressmakers wheel to first laydown a pattern where all of the raised rivets will be.This will leave a nice straight properly spaced line of indentations that I can use to then fill with a raised rivet.It should speed up the process one would think thats going to take a long time anyways.Any input on this is welcome.Another question people ask me is; Is a clear thinned white carpenters glue rivet going to stick ok to FM?And what about the color? I know Ed from Flite Metal says go this way,that the rivets will blend in with the FM aluminum color.Some say to just use the wheel for the indentations and that that will suffice.Another option is no rivets.I'm still open for ideas.

RE: Ziroli DC-3
I counted the rivits on my yellow p-47. I ended up around 28,000 plus or minus a few thousand. I would think tou need a bunch more than that.

RE: Ziroli DC-3
My mustang had 12-13,000, and based on my recollection of seeing a few, I'd say well over 100,000, maybe 200,000. This plane has a LOT of rivets. I remember cringing as I walked one down taking pictures of everthing for a scale project (currently in hibernation). This is where "full scale" can get compromised. Up to you my patient friend! Count on about 300 rivets per hour overall.

RE: Ziroli DC-3
Steve,
You have your work cut out for you!!! I estimate 100.000 rivets. All the edges of the panels have rivets spaced so closely together, you cannot get another in between! The wings are full with rivets. I am glad I use litho and can put them in with the sowing wheels. I don't envy you. I did about 200 rivets using glue on the vertical stab before silk and shellack and I was thinking I was glad I didn't have to do them all over the plane.
But if you do it will be worthwhile I am sure. It will be a long winter so.............

RE: Ziroli DC-3
Yes, consider it carefully.
Once you lay the first rivet, you are committed, so your estimate on time and your available schedule should be well understood.
When I recently did my Mustang, it was prior to last year's Joe Nall. I estimated 8 hours to do the rivets, which I burnt into the fiberglass/primer coat with a sodering iron tipped with a brass tube (flush rivets). Once I did the first few lines, I realized I had made a very poor estimate- it took 40 hours! It took some all nighters to get it done in time, but there was no turning back. I'm very happy with the way it turned out, so it was worth it. BTW, there is one small line of rivets on one panel missing on the whole plane- $1 to the person who finds it!
I'm sure you'll do a great job no matter how you decide to proceed. Your patience and motivation on this project has brought you very far already, and you're on the home stretch. Good luck!

RE: Ziroli DC-3
Just wanted to show a picture of the standard cowling with a Saito 170 3 cylinder in it.In my opinion it looks ok,the valve covers stick out maybe 3/8" .I could make some wide blisters or I could just leave em stickout ,any thoughts guys?What do you think?This way I'll have radial engines.Right now I have three options;Gas:US41's
;Glow: Saito 180's
;Glow:Saito 170R's
;Glow: Saito 180's
;Glow:Saito 170R's

RE: Ziroli DC-3
I think you're nuts matey!! 
The sound from the saito is fabulous-dont waste 'em! If you look at the DC3 build in rcscalebuilder, http://www.rcscalebuilder.com/forum/...858&PN=1&TPN=1
Its on page 3 and you'll see a tutorial on modifying a cowling by cutting it into four pieces and adding fillets. Its really simple and effective.

RE: Ziroli DC-3
Got some pics of the new cowl,I may or may not open the cowl flaps some,I kind of like'm closed.Still lots of work to do on the cowl.I've ordered another S 170R and have also ordered a Sonictronics glow driver and Keleo-creations exhaust rings.Kelvin was very helpful and said he'll modify the rings left and right and extend the stacks back on an angle the same as the DC-3's with straight stacks/no mufflers.Should sound pretty nice.

RE: Ziroli DC-3
Here is my fiber Classics DC-3 with flaps closed. It started life flaps open but to me it looks better as it is now. 126" span 34# Saito 100 singles making 21# static thrust on Kavan 14" three blade props.

RE: Ziroli DC-3
Unbelievable job! I just read through this entire thread and I'm really glad you went with the radial's! The cargo doors look excellent as well. I was just recently at the Carolinas Museum of Aviation, they have one of the few flying DC-3's dressed up in Piedmont Airlines colors. The top is painted white (to deflect heat I am told) but the rest of the airplane was aluminum and very shiny! The one thing I did notice however is that the control surfaces were covered in fabric, not aluminum - I was wondering if that is typical of this aircraft as I noticed you covered your control surfaces in foil? They also had a non flying C-47 dressed up in military colors that had seen better days, I wish I had known then that you were looking for cargo door detail as I had a great opportunity to take any pics you could have wanted.
Great job, I can't wait to see this one finished!
