Josh another great job explaining what to do and why. As a beginner you made this look very easy and something I am gonna do this weekend. StoneKap rules...

I built this project and is very easy and fun to fly.
Some friends on the field did not believe that would fly, and then were impressed with his performance.

very cool!

I built one very similar to this with out the (semi) vertical stabilizers, and my kf step I made like 7" from the nose (not tapered to the ends of the wings). It is pretty squirrely. Should I add the (semi) vertical stabs, add taper out to the ends of the wings, or both? any suggestions would be appreciated. How can I add a picture of what I have fore reference?

love the delta i want to know how to make it faster with adding a little of weight

Can we get some good plans? The plans provided are hard to use if all the measurements aren't added.

Josh,
You refer that the tail skid is on the plans. I don't see a jig, design, or template for the tail skid bending. Any help would be greatly appreciated. I actually bought a small 3/8" wheel that I want to put on it, to complement the 1-3/4" mains; and I'll use a similar bend to keep it on. Just need some guidance on a diagram.

Love the whole swappable series!!!

Regarding the landing gear, when Josh says use 0.7mm music wire I think he means 1.7mm (1/16+") I used 3/32" (2.4mm) .7mm is too small.

I just finished building this plane but have not flown it yet. It was fun and easy to build, the instructional video realy helps on the details.

Hey i am new to scratch building and was wondering how to print outr the plans because out of my normal printer it does not print the same size as it should be

Trying to sort out the CoG, where am I measuring it from. On the wingtips, it always tips

It will be my next plane after the FT Flyer. Great Build Video. And keep it up with the Locals :)

What a brilliant idea. I hope to build the full series. Very many thanks for the inspiration.

Great build video guys and thank you. This Doller Tree foam board. Could someone please let me know the UK name for it, and where to get it. Wingnut

Best build video ever. Nicely done guys.

I love me the Delta. I can't wait to get a chance to put this on my fuselage.

Regarding Foam Board sources.

Try your local Art Supplies store! Yes believe it, the local arts supply store.

I was most surprised to find 3mm and 5 mm white and black Foam Board, balsa, and metal rod (for landing gear and servo push rods). I bought a large sheet enough for the FT Flyer for $NZD13, but the left over was 50mm too short to build the Delta. Dammit!

The stuff they have was all at least half the price than my local hobby store charges (and its exactly the same stuff!).

Thanks for the updated information. Helped out alot.

Does anyone know where you can buy this foam in Australia?

I just wanted to say thank you to you Josh and Josh... your videos are interesting, entertaining, and informative. I have been deployed for the last several months and I get to head home in February. Maybe my son and daughter will join me in building these flyers. Thank you for the great video and links to the sites to buy the equipment. Sincerely, HAYDEN J

Can this be used as a trainer or this is just too fast?

Really cool concept, and super easy to build

Hi i'm just new into RC stuff and i hound this one amazing one thing I can't find though is the Red Brick 25A ESC, can I use a Red Brick 30A ESC instead of a Red Brick 25A ESC or a TURNIGY Basic 25A v3.1 Speed Controller. I need your help.

Great instructional video josh, the swappable series will help bring new fliers into the hobby and also aid in there progression.
It did make me laugh how many times you said " Perpendicular "
Keep up the good work... Steve

awesome work guy's.

i have just built up a "FT Flyer" (Blue dart) using your "folded" fuselage design.

looking forward to trying a Delta when my skills catch up to my ego.

Cheers Jimmy

What battery did they use in the video? It's not the one that was in the parts list. Will the parts listed still make it go vertical?

Log In to reply

5 Star article no two ways about it. So many tips here that go way beyond just the Delta Wing!
Log In to reply

A quick question, when is the best time to do the painting on the plane? My guess is before the assembly.
Log In to reply

is it me or am I missing the other side of the wing with the "key side" on the tiled plan?

Thanks

Hey I made a Delta but am having problems. Where is the CG on this plane? I was thinking it was 40% while making the plane but then heard it was 25% .... so what is it? I also have a 20C 1800mAh lipo weighing round 100g which im putting on and the motor manages to lift the plane vertically with a 9x4.7 slow flyer prop. Yet it still cant really fly. Is it too heavy? Tail heavy? Built wrong?

I want to try these but there are no dimensions. Where can I get them?
Log In to reply

Thanks Josh for this wonderful flying Delta Wing. I built it a month or so ago and it has flown several times. She is beautiful in the air. I now have the Nutball, Delta Wing, and the FT Flyer completed and are flying when weather permits. Almost finished with the the building of the Bloody Wonder. Thanks again for great flying machines.

instead of placing the prop to the nose, can i modify the design and place the prop between the ailerons?will this effect the flight?CG wont be changed...

Hi,
Please can you advise where the Cand G should be on the DELTA...thanks.It would be nice if typed instructions are on the site with the videos....thanks !!

I started with U-control about 1971 then about 1983 I built a Sig Kadet nitro, a Heath Kit radio and receiver on the 6 meter band and taught myself to fly. I got out of the hobby for quit some time but about 4 years ago after retiring I got back to it. My gosh how the technology has changed! I always did like building. This Swappable series is really a lot of fun. Josh and Josh, David and the crew are a great bunch. I've learned a lot! I've had a blast with the Nutball and the FT Flyer! Had to do some rebuilds but that was half the fun of it. I just finished the FT Delta and I'm looking forward to putting it in the air. I just hope these 71 year old eyes and reflexes are good enough to keep it in the air. To the Flite Test Crew -- Keep up the great work!

I scratch built this plan, thinking it would be a good plane for my son, but I can't get it to fly. I used the heavier brand foam board and balanced the plane right where the CG is marked. I am using the blue wonder and a 1300mAh battery that is almost to the servos to get it to balance. I have been flying 10 years, but I am missing something with this plan.... any suggestions??
Log In to reply

Built a stretched version of the original, added winglets and an extra KF step. Pretty slick and fun plane.
I've also added a skid type deal to the front of the power pod to aid in grass belly landings. has two sides sort of bullet shaped, joined by a piece that goes flat on the underside of the pod. It's held on with the two skewers that are used if using landing gear.

This model flies like an absolute dream! Very tame with the Suppo 14.5kVA motor and a 2C 1000mah battery. Needed to place this batter really far back and it balances just forward of the CG on the plans. Much easier to fly than the Nutball which I've yet to keep in the air longer than 10 seconds! lol

I would like to see a pusher mod for this.
Log In to reply

I know that this is kind of pathetic, but I have no idea which channels to plug the servos into on the rd. I only do rc cars, and this is my first plane. The plans were great! Thanks Flute Test!

Hey guys I just want you to know this is my first scrach build. Its also my first real rc plane. I have done ok with simultaors so we will see.
Log In to reply

I would like to see this plane converted to where the powerpop was converted into the body of the plane and twin duct fans mounted near the middle of the wing against the converted powerpod

I didn't have any foam so I used cardboard
(Lego box) WORKS GREAT!

Just completed its maiden voyage and was surprised and thrilled with my first scratch-built airplane—the FT Delta. Josh has designed a great flying plane that was fairly simple to construct. The recommended servos (blue) operated at different speeds however with some fine tuning on my Tx, I was able to control surface throws with no problem. I decided to leave the landing gear off opting to hand launch the plane which worked fine on the first flight. During the subsequent launch, the prop flew off as I powered up the plane. Would prefer an alternate method of attaching the prop other than an O ring as on the suggested power plant. Otherwise, the plane needed little trim to fly great on its first flight and tracked straight and true on low rates completing lazy rolls effortlessly. High rates made flight a bit difficult due to increasing wind speeds at the site but still looked great to onlookers! Definitely will be building more of these in the near future!

loved building and flying this...my first ever RC plane!! Can't believe I'm flying!!

Can anyone give me dimmension / angle of the fin gauge" I didn't get one in my speed build kit. In fact the little poster it came with has it labeled as the flyer.
Log In to reply

I would also like to add that the tiled plans do not have the fin gauge, I also noted that the cover page shows 16 pages, but the file only has 12. As a side note I have built the FT Delta with the pylon, and pontoons from the Snow Ball, will report back on how it flies.

I realize this is an older plan so I hope someone reads this, if not I will jump on the forums. I'm an absolute newbie to flying and building. After pouring over you tube, websites, podcasts etc I decided to jump in to building with this model. I have a very beginner question. I followed the plans and watched the video which was very helpful. After I was about two thirds through a question occurred to me. Is there some structural reason to have two wing halves and join them? If one is scratch building this model, wouldn't it make sense to build the wing as a single piece from the get go? I understand that the speed build kit might come that way to facilitate smaller shipping containers, is that the only reason for a two piece wing on this particular design?
Log In to reply

I've made the plane recently but i am having some problems flying it. It flies great when at speed, but from time to time it starts spiraling down and i can't recover it. I tried moving the CG slightly forward, which does seem to help a little, but it still does it. Any recommendations on what i can do to fix that?
