Hey guys thanks for the nice comments! Coroplast is 4mm. With a 2200mah 3s weight is 930 grams. 41 inch wingspan.

Nice job Greg! Thanks for building and sharing your F&L with us.

Thanks Lee. I've since gotten alot of complements from club members on the design. I kindly direct them to this thread so they see where the plans come from. This is my second FnL the other was a small one, both fly great. Also they want me to build it for them. They are all retired, I am not, they think I have nothing else to do 😄.

Funder & Lightning maiden flight (2 min 3 sec)

This is the first wing that I cut for myself using my 4 axis CNC hot wire cutter.

Regards
Ian

Ian,

Great job!! Thanks for building my plane and sharing the video. Please take a few more detailed images of your build and share them with us. I'd like to see more of that wing.

And I agree with your camera man - wicked vibration either from prop or motor. May want to look into that.

Enjoy the F&L!! Get some buddies to build a few and add streamers for dog fights!

Building one now out of DTFB. Increased size a little to 42”. Debating on whether to double or triple the nose and thinking of 3D printing a motor mount that will fit around either the 2 or 3 sheet thick nose.

Planning on a turnigy 2838/8 1100kv motor.

Thanks Lee,

I’m using a prop saver but the prop definitely needs balancing.

I’m really enjoying flying the FnL again and I will certainly take some pics and share when I return home.

Regards
Ian

Hello ,

Some pictures of my Funder & Lightning.

Weight : 13.4 Oz in order of flight with a lipo 3s/1000

First flight soon.

Very sharp, great looking plane!
I'm sure it will fly as good as it looks, too!

Do you have a pic of the bottom side where the battery ended up balancing?
Thanks!

Congrats! Nice lookin' F&L. Can't wait to see the video.

Lee, (or anyone) I was wondering what you're using for the weights on the bench. They look like they work quite well.

Thanks, Ryan.

Ha! Thanks. I call them “Alumilead” bricks. Take 1” square tubing, cut them into 3” long sections. I fill mine with molten lead or lead shot mixed with epoxy. The right angle of the tubing works great to line things up.

Even on 2s the plane can hover at 70% throttle, so more than enough throttle. I had to re-build the tail due to hanger rash, and we added some wing tape for color. I also used 3m super 77 for the first time to install some logos that we printed out on normal paper with our printer - something I'll certainly be doing more of in the future. If/when I wind up building another one, I'll be scaling the nose to be quite a bit longer - I'm not crazy about how the props are out further than the nose on this one.

I tried to take a movie with my cell phone - it's not too great, but shows it has plenty of power now. Flown by my 10 year old son, who is getting to be a better pilot than me.

I agree that it would look better with a longer nose.

The twin F&L I built was not only a great flyer, but more importantly just a hoot to throw around in the air. If you haven't tried mixing in yaw control from the rudder stick using differential thrust it is worth the trouble. I couldn't tell if you had two ESC's, or no. Rigged it both motors in standard rotation.
I kid you not, mine would do 3 1/2 flat, yaw rotations from a vertical entry before it fell out.

One of the coolest things I ever saw. That 10yr old pilot would love it.

I did actually build a new one with a longer nose. I haven't decided what decals to put on it yet, but it's been up in the air a few times and works well. Both of these have differential thrust via radio mix for virtual rudder. I scaled the mixing at 100% on the first one, and it makes the plane pretty unstable so we never really use it. I also added it on my mix for the 2nd one and put it at something like 30% which makes it actually usable for turning. I've never managed to get a single plane into a flat spin, but I might try on the short nosed one.

Lots of fun to be had and things to learn with these planes.

Past time I built another one.I have grandsons that fly fixed wing, but have yet to try an F&L. I'm feeling like I have slacked in my duties as a nonno, better get to work and rectify that.

"Virtual yaw" is a good term for the diff-thrust/yaw.
