Official FMS 1500mm P-47D Razorback Thread

[davegee]

Elbee,
Yours is the spinner that should be used probably but the shiny alum. looks nice. I think I can get this below 1.5oz which should be able to balance ok.
The thing I like about the 3d printed version is after you get the final version everyone after is identical and the detail is amazing. I think painted with Alum. paint and polished it will look like alum.
Best Regards, Rex

Elbee and Rex: great jobs by both of you! I have been beta testing Elbee's V2 3D printed CE prop dome, and with several flights on it now with two different airplanes, it withstands the rigors of vibration, speed, and other stresses with aplomb. It screws on by finger torquing it for the proper alignment of the base plate with the prop hub behind it (see above photo of the real one and how it aligns.)

I'll attach a few pics I took this morning using my Penrod and Sam FMS P-47 as my testbed. The prop dome is in primer coat, and as soon as I get the paints I need from Amazon, I'll start working on making it mirror smooth and shiny.

It's not lost on me and probably many of you that tomorrow is the 81st anniversary of D Day, and I think the real Penrod and Sam probably participated in sorties that day, although the famous pilot who flew the real plane (Robert S. Johnson) and got two kills before he was sent home with 27 kills was not there that day.

Rex, I'll be standing by for your aluminum prototype when you complete it to do beta testing on my airplanes. It's looking great, so far!

Cheers

Thank you so much for remembering 6/6/44.

I had forgotten, sadly for me.

I do remember seeing the film "The Longest Day" at the Orpheum Theater with my Dad.

I didn't quite understand it all, I was 9 at the time, but it is a great childhood memory.

Thanks Dave, what would we do without you.

Best, LB

Davegee,
I was thinking of D-Day last night while working on the spinner. My Dad had friends that landed on D-Day and I can remember stories they told as a child. Many sacrificed everything for our freedoms today.
The spinner in the pictures are of your spinner. I will drill the 4 holes in the base. Do you know the hole dia. that Elbee used on his spinners? The little safety wired bolts you will have to add. If you know the dia. of them I can drill them also.
Your Penrod and Sam looks great. I need to finish my cockpit and make an open canopy. This winter I want to add the better scale cockpit and P&W Eng. Not enough hours in the day!
Best Regards, Rex

Hi Elbee and Rex: I remember seeing the premier of The Longest Day movie on or near June 6, 1962, in Aurora Colorado at the East 70 drive in theatre. Besides the fun of going to the drive-in, the movie, seen with my two older sisters and my mom, was just a memorable experience that I crisply remember to this day.

Around 2005 or so, I had a new captain student on a trip where he got his initial operating experience on the 747-400 that he had just completed his ground and simulator training. During our 6-day trip, we got on the subject of the Band of Brothers mini series. Turns out, his dad was in the 101st A/B, 501st Parachute Infantry Regiment that dropped into Normandy in the early morning hours of June 6. The parachute drop stripped him of all his equipment, except for a little hatchet he had strapped to his leg. He splashed down in a flooded field that startled a couple of German soldiers who looked for him but didn’t find him. He made his way to his objective and was awarded the Distinguished Service Cross, second only to the MOH. His service followed the BoB miniseries, ending at Berchtesgaden, Germany when the war ended on May 8, 1945. I had the distinct honor and privilege of meeting and talking with him at his home for three hours one day. He has since passed away, but I will never forget him. His name was Donald E. Zahn, a true American patriot.

Hi Rex: sounds great.We’ll wring ‘er out with your prop spinner when I get it.

Regarding your question on the hole diameter of the four small holes near the bottom of the printed CE domes, I come up with just under 5/64" diameter when I tried to put a drill bit through the holes. So something in that area would work fine, I would think.

cheers

Thanks, Dave, for measuring. Also, do you know the thickness of Elbee's back plate? I can cut that amount off the base end so the length will be the same. I'm planning on using .020-.030" styrene sheet for my back plate on the alum. spinner. Not any load bearing structure so I think this will do.

Hi Rex: I just measured the back plate for the spinner from one of Elbee's CE prop domes. It is about .040" thick (including some layers of primer.) So, if you could make the back plate .030" thick, that should work great.

Thanks!

Hope U guys don't mind me butting in.... But what Yas r doing on one small part of an aicraft. Is awesome.. reminds me of my 80s schooling
an Ozzy 40 thou. Around 1 mm.. shows the accuracy Yas ar working with... Very cool
... My brother and I spoke of. D day.. we always remember those young men.. especially that black and white footage of Omaha. That's well seen.. hope not outa line their cya

[Elbee]

You know you are among friends. Best, LB

[jetfool]

F4u ausie,
Just chime right in, Mate, your more than welcome to add your pro's and con's. The more friends the merrier time we have.
For a foamie we are probably taking it to far but this P-47 really comes alive with little details added. Not making museum scale but we are using the TAR theory (that's about right) and the measurements between us keeps us in-line to visually see what we are doing.
It's going on 3 yrs. since we all started sharing ideas and I think it's great that we are still at it. For not meeting anyone face to face it seems like we are old friends.
Best Regards, Rex

[f4u ausie]

Thanx rex..... The tar is a newy 4 me.. will spread that one

[davegee]

You can meet us for a cold one at the Dewdropinn or the It'ldolounge anytime! Always enjoy your inputs and I remember well our working together on the bigger, more scale props from the FMS V3 Corsair to the FMS 1.5m P-47s which has been a great scale add-on for these models. To me, that was a huge improvement for making a more scale looking and flying P-47. Some of our work is just an extension with stuff you and I and others came up with a few years ago.

Best,

Davegee

I use the enclosed photo of my Penrod and Sam just for illustration in this post. Dan G. and I have the fortune of living in a beautiful area in northwest Wyoming, and the field we fly from always has the impressive Heart Mountain in the background. I have always had a plan to climb it someday since we moved up here 5 1/2 years ago, but yesterday, I actually did it! Trip was about 11.5 miles from the trailhead to the summit and back. Weather was beautiful, if a little windy in spots. The first half of the hike is in a clear meadow area, and then you get into dense forest (I mean Dense!) for the rest of the climb to the summit. It was so dense that in most areas you could not see out, and the trail was pretty steep with a lot of switchbacks. But then, all of a sudden, you're now above all the trees and at the summit! Summit height is 8100 feet MSL with about 3,500 feet vertical climb.

I have climbed a number of "fourteeners" in Colorado in my day, and to be sure, those were more difficult, some taking two days to summit. But this was satisfying making this one after a long absence from rock climbing and hiking. The view from on top was impressive!

Gives me a renewed appreciation for the things around me, and the beauty of spectacles like Heart Mountain. The grizzlies still live up there, but we didn't see any today, fortunately. But everyone who was climbing yesterday was aware of that possibility of an encounter and had bear spray just in case!

Happy trails to all!

You are very lucky to live where your view is breathtaking. Glad you are still exploring and able to do things you want. Hope we all have many years to do that.
Congratulation on your climb, Rex

Thanks, Rex. I did find that age has caught up with me as young 20-30 somethings passed me on the trails with little effort. I remembered when I used to do that so easily, but not any more, I guess. Still, I'm glad I did complete the trek and am happy the challenge worked out ok.

I took my "Ole Cock" FMS P-47D up for some test flights of the new 3D printed Curtiss Electric prop dome that simply screws onto the propeler shaft. The latest version design is one courtesy of Elbee which really looks great. I've printed a couple of them on my machine and have been verifying the prop domes will be usable going forward, for my planes. On the flight I had with "Ole Cock" 2 weeks ago, even through I had tested the gear operation and everything else ad nausem, when I got it into the air, I noticed that one of the gear retracts had failed with the gear halfway up and down. Tried to recycle it several times, but eventually I had to make a partial gear landing. Upon inspection after the flight, it looks like that retract suffered a sudden and fatal coronary in flight . No saving that one.

Landing went pretty well for being a crippled aircraft, and it made a dramatic turn on the ground as it slid to a stop. Mostly minor damage, although it is a pain in the neck to replace things like gear servos on this airplane. Finally got it done with a spare I had in my parts box, and today I reflew it to check the gear was working properly. I should mention that most of the damage to the plane in that landing was to the prop hub and some of the propeller blades. So, I needed to send to Tallahassee to FMS for a new prop hub, which is supposed to arrive today, which was a pleasant surprise.

I'll attach a pic I took of the P-47 on the ground after doing 4 flights today. The V1 printed prop dome is in primer grey, and is being used for tests. Elbee made further improvements with a V2 version that has some detail additions at the base of the dome. Those are "in paint" now, and I'll take more pics when I get the final V2 painted and installed on the plane. I thnk it will look pretty good. I borrowed a prop from another of my planes, a Hamilton Standard prop.

Rex is working on a machined aluminum dome that will be the final version for this model, with the printed ones as backups should anything happen to the aluminum dome.

Battle damage but sounds like the rugged Thunderbolt brought the pilot home safely. #d spinner looks good. I have been a little slow on modeling, family funeral, but should make progress on Dave's spinner this week.

I got out to the field today to break in the new radio. I got a new NX8 plus, great radio so far, don't let the '8' fool you, it's not like the old DX8, it has 20 channels!
So, it's like having to maiden every plane over again, but at least the signal problems should be solved. BTW, I finally found the video explaining how to do flap elevator mixing while in the air, have a look...

Hi Rex: sorry for the loss in your family. A lot of that going around lately, unfortunately. Whenever you get around to the spinner is fine. I am still testing these 3D printed prop domes and can use them indefinitely until the aluminum dome arrives for testing.

Take care.

Davegee,
Thank you. Stepbrothers' daughter, 37yrs. old. Freak golf cart accident. From her wishes 8 organ patients will receive hope for prolonging their lives and giving them a future. Been a rough week, our girls are same ages, and they all grew up together. Wife is headed to her sisters (Columbus, Ohio) today because her boyfriend, 79yrs. old, is in last stages of cancer (Hospice is helping). Just me and the dog batching for a couple of weeks so I hope to finish spinner and ship everything to you soon.
When it rains it pours, Rex

[f4u ausie]

Sorry rex freak accident.. horrible regards Craig
