Thanks for the picture. I took a couple of liberties with the build as I was concerned about my build abilities. I have not gotten a dual pushrod elevator working 100% so I modified by cutting out a notch in the rudder and spanning the two halves of the elevator. It's not ideal and weak at the rudder hinge line so I reinforced with a bit of carbon fiber.

Ended up putting the servos down lower and routing through the side of the fuse.

Used the smaller pod from the nnChipmunk, that I reduced the length on and set it up in regular FT style with the dual BBQ skewers in the front and one going through the side.

I spent a little time trying to build the speedwing and had some challenges. My wife wouldn't let me use one of the kitchen knives so I tried with a razor blade and some sandpaper but was just not happy with the result. I am planning to build more of the standard FT wing to keep things simpler. I will use undercamber wing tips but keep the multiple 50% score cuts and use the line on the wings where the paper would be removed for the speedwing as my cut line. This mimics the way the nnMig3 was built which flies beautifully for me. I'm not looking for speed so hopefully this will be fine.
Love it Nic! Can't wait to build this one! Maybe I'll actually take my time and give this one a good paint job this time. Nice flying in the video too!
I would love to see a P-40 Warhawk in this size, or even the Sonic series size. Nobody does a foamboard Warhawk, and they're just such an iconic aircraft...

Here is my version I put the servo's through the top of the wing to protect them from my less than stellar landings. Also used an aluminum spar for those speed runs. Now just have to maiden before the paint dries! thanks Nic !
Looks great Mile Hy! I was able to finish my version of the standard wing today. Very pleased with how it came out. I love these planes because the planes are basically balanced on the CG before adding the battery.

This looks great, Nic! I love Spitfires, so this is a must-build for me. It will get serial number 6.
And that's a beautiful example you have there, Mile Hy!
Today I nosedived my FT Arrow into the ground at 61 miles per hour (measured via my FrSky airspeed sensor) and cracked the airframe in half on both sides of the paint stirring stick I was using to reinforce the airframe All the electronics are fine, and smashing stuff is actually kinda fun, so overall it was a good outing. I like the Arrow, but the tiny electronics compartment leaves a lot to be desired, and it's a pretty drag-heavy airframe. So I'm using this opportunity to transfer the electronics over to the nnSpitfire 800 that I've been eyeing ever since Nic released it.
I'm taking some vacation time over the next few days, so prepare to be barraged with questions!
I've never built a single-servo dual-pushrod setup before, but I'm interested in trying it that way for this build. Does anybody have any tips for that? I've seen some interesting designs where there's a "T" right after the servo connection (for example https://static.rcgroups.net/forums/attachments/9/6/3/8/ai11582262-141-thumb-ch49.jpg?d=1195677774), but the plans make it sound like both pushrods are just inserted into the same servo hole. I don't see how that would work without destroying the servo arm. Am I overthinking this? Should I just solder a second pushrod to the first right by the servo Z bend?
Thanks for the plans Nic! You've really taken DTFB to a completely different level.
Thanks! Let me know if you build one, would love to see a clean paint job. You're in luck because I'm actually working on a p40 already. No eta yet though
Nice one Nerdnic. Thanks for the plans. This will be my next build. I hope I can use my Turnigy D2826-6 2200kv, as I crashed my Sparrow and have it spare now.
Btw, my Chipmunk has broken into pieces many times, but it still flies very well after repairs. Thanks for that one also!
That motor with a 7x6 on 3s 2200 40c is one of my favorite setups! Good thrust and about 80mph top speed.
