Official FMS 1500mm P-47D Razorback Thread

[Grossman56]

The advantage to living in Cody is that I can see all of Dave's creations in real time.
Up to his house today and checked out Hairless Joe. If you think the pics are good, the real thing is overwelming!

Put in a pic with the right back drop and in black and white and you would swear it was a WWII period picture. Might be an idea to get the pic that Dave worked with and reproduce the angle. Something like this...

With the new Fliteline P51, the vertical stab is a separate piece like the FMS 1450 P51D. It should be a much simpler process with nowhere near the risk.
As someone who has seen Dave's work up close and personal, pics do not do them justice.

Very cool Dave glad to see some one has some persistence and not just being happy with a stock Cooke cutter boring arf like the majority of the population. A++++++++++++++

Thanks, James. Most of my models now that I come to think of it are modifications of something sold off the rack by one of the major rc companies. For my EFlite 1.5M P-51D, I carefully sliced off the foam fillet that runs from the fuselage to the vertical fin as this part did not come in the first batches of NA P-51D models from the USA. It was a bit risky doing this but it worked out great and the airplane flew great even without this part. It is painted up as LOU IV/ATHELENE, flown by 361st FG commander Col. TJJ Christian, Jr. in WWII. The stock paint job from the manufacturer roughly imitated a modern day version of this airplane, but is just a fanciful paintjob of something that never was in real life, at least in WWII. I tried to make my model look as close as possible to Christian's airplane in the summer of 1944.

Yeeeaa. It works the vid and the sliding canopy :partying_face:

Here is another attempt to play my recording of the working canopy for my P-47D Hairless Joe. Here is the link below:

By your description. Simply more expo just may help.

I'll play around with that. I did bump up the expo some as an experiment, but didn't really dig into it more than that. I need to do some trials going up and down the runway at various expo settings. Maybe something will materialize. Thanks for your input!

Cheers

What about reduced rudder throw sounds like U can't move the pushrod to the outer hole to reduce it... We have my first scale day at the club tomorrow. Will post pics on what did U fly. In the arvo

I've never been able to really resolve this with these FMS P-47 airplanes. I do need quite a bit of rudder throw for takeoffs and landings, but for the straightaway takeoff and landing rollouts, it would be great to isolate the tailwheel to freeze it straightforward like the real ones do, and then "unlock" it at taxi speeds so I can use rudder and tailwheel to taxi on the ground. Right now, all my 8 channels are being used so I might try one of my other jugs to play with this with tailwheel control on a separate channel, or something.

What would a higher expo on the rudder do for me, so I have to really crank the rudder stick to get a big movement on the rudder/tail wheel? It starts out fine on takeoff rollout or landing rollout, but then I seem to overcontrol it late in the takeoff or landing roll and it sashays left and right instead of just going straight. I'm sure there is a solution somewehere, I just have not figured it out yet for this airpalne.

By all means, please share pics of your flying meet so we can see what all you guys are flying!

Looks amazing Dave!
She flew as well as she looks I gather?

Dan

Yes, the only thing I didn't care for is that the tailwheel turn left and right is too high and I'm not sure how to dampen that. It's wired into a control board in the fuse as is the rudder so they sorta work together but I don't have the ability that I know of to reduce that tailwheel throw. I get some fishtailing on the takeoff run close to liftoff, and on landings regardless of the rates setting, it is hard to just have a nice slowup and then put the tailwheel down softly and not have it sashay back and forth. I don't think my other jugs are like that.

Would it help to increase exponential for the tailwheel for steering?

Otherwise, it is a great flyer just like the others that I have had. Really a great design by FMS.

Cheers

Davegee,
The photo's look fantastic. Your flight tests are a great help for those of us that are wanting to try the same thing. FMS should put you on their payroll for inovations.



Best Regards, Rex

Thanks, Rex. Since about 2000, study of the P-47 Thunderbolt has been a passion of mine. I enjoyed the challenge of converting this foamie, much thanks to James in California who did all the heavy lifting to make this conversion possible. I don't hold out much hope that FMS or any other company will make a model that will be acceptable to me as a bubbletop, but I haven't totally given up yet. And if that never happens in my lifetime, I'm happy I have this one completed and flyable.

Cheers

Dave

Absolutely stunning Dave great 👍 job congratulations on maiden

I remember our collaboration on putting the larger prop on these FMS P-47s a few years ago. That has been a wonderful mod, my flights with them you just have to be a bit careful not to scrape the prop tips on takeoffs or landings. Not too hard to do, but you have to be careful. But it sure Looks great with a more scale prop on it!

Cheers

I got two more flights in on my Hairless Joe, and one on my Freewing F9F Cougar. Both flew great.

On the second flight of Hairless Joe, I mounted a scale foam 108 gallon drop tank on the belly, attached to the EFlite drop servo. I used the "I" button on my DX 18 transmitter and pickled the tank when it passed me at about 80 feet altitude. Just as expected, the tank immediately became unstable, tumbling end over end to the cross runway below. Just made a small dent in the aft end of the tank but it worked great. Powered canopy hanging in there great.

A few more pics from today.

Cheers

That will be perfect! Looking forward to doing a photo shoot at the field sometime soon.

[Grossman56]

Absolutely!! Do you know if the scale of the two airplanes is the same? The P-47 is 1:8.28 scale. No matter, it would be a great photoshoot on a nice day with the two of them!

Cheers

Davegee

Yeah, Callie said it was closer to 1/8 than 1/7 so it should be good.

Actually, all I did was copy the link from your E mail and posted it here, it worked!

Thanks, Craig. Thanks to Danger Dan, I now have posted the short videos on the canopy movement that I tried to download several days ago. I'll have to see how he managed that!

Cheers

That's too bad. The P-47 has loomed large for me since I got into rc flying in 2000. I started with a few trainers, all glo powered at that time, and built and flew three Aerotech 1/6 scale P-47s that were flown in scale contests around the country. Those three airplanes are now in museums around the USA. Building this foamie was a nostalgic throwback to those happy days. Thanks for making the effort to do this conversion. Had you not presented yourself, I would probably never have done this project.

Best,

Davegee
