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.

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

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!

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.

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.
