I’m almost finished with my second trio of T-bolts. I can’t wait to finish them. They’ve been waiting for decals for over a month now. I’ve been too busy working on my Senoir Design model to work on my “play” models. Don’t you hate it when you have a model (or 3) that only need 1-2 more hours, but you can’t find the time?
— we’ll build and fly this one next semister. It’s a fly or fail class, so if it dosn’t fly, we…fail.

Hey Joshua! Nice work on the bolts! The -72 looks so odd sitting there lol. p.s. the Jet looks really sharp too. good luck with it, let me know how it turns out!
The models are looking terrific. A nice family photo 
Where can I learn more about your design project?
Simply fascinating.
Haha…like every build!
Great looking trio of birds. Do’t keep us hanging…post the final versions.
The triplets look great.

What’s up w the plane on the right. Seems to have an extended engine cowling. Someone put a liquid-cooled engine in a 47?
WOW !
Outstnading Builds so for
Well Done
Bud
Excellent looking P-47 aircraft.
Please tell us more about the Fly or Fail class and that very cool aircraft project.
Thanks

That is the XP-47H. After the war, two razorbacks were converted to carry a Chrystler engine (I forgot the size off the top of my head). I love T-bolts, and I thought I’d diversify my collection with a P-47N and XP-47H.
About the class:
I’m an Aerospace Engineer major at NCSU. Our senior year we build a UAV (RC jet) to meet “customer requirements” Past requirements included Post-Stall Manuverability and Pusher/Puller Conversion in less than 24 hours. This year, we have to meet a 30 knot stall and a 90 knot cruise…without using flaps. We have to use a “varible geometry wing”. It also has to withstand ±6g’s. The other 2 teams are using telescoping wings. We wanted to do something different (even though telescoping wings are a very good idea), and so we looked into a swing wing and an oblique wing. We abandoned those two for many reasons, and settled on a folding wing configuration. It might not be the most efficient method, but we wanted to do something orginal and different from the other teams (and when was the last time you saw an aircraft fold it’s wings in flight?). We’ll design it this semister, and test/build/fly it next semister. It’s quite a task. And like I said, if it dosn’t fly, we fail. No pressure or anything.
That pic of the XP-47H looks like a pregnant P-40! Would make an intersting model, though. Is it a kit, or are you doing it from parts? The other two look great so far!
Hey Joshua… Here’s something to make you feel better if your jet crashes and you fail… at least you’ve learned how NOT to design a plane!!! For my intro to engineering class, we had to build a bridge. Points were awarded based on the weight it held. My group’s held 20 lbs. Pretty embarasing. But now I know how to not design a bridge…
Looks good.
Hey Josh, no tail?
So you weren’t allowed to use leading edge slats or anything on the wing? What about using a variable-incidence wing?
I’m heading to college to major in aviation engineering soon, I’m just curious.
Nice trio of Jugs.
Regards, Rick
No Slats either. A varible incidence wing is something that we didn’t even think about. The thing to remember is that you can only pitch a wing so much before it stalls. Both a normal wing and a varible incidence wing will stall at the same angle of attack. Makes me wonder why they used it on the Navy Crusader though. Hhmmm…
P.S. That design is from last week. We just got a decent tail size this afternoon, so I’ll update the model.
STOL capability, slower approaches, loiter speed, fast cruise. It was dropped on the A-7 though, too complex and expensive.
Just one thing I thought up quickly.
I doubt it would allow for a 30 knot stall though, that’s VERY slow.
