BUILD, FLY, CRASH, REPEAT

Foam Board Old Timer

Designed by Chet Lanzo in the 1930’s, the Lanzo Bomber was (and still is) a very popular free-flight and R/C design with it’s pylon mounted wing and iconic diamond section fuselage.
I decided I would try to build one out of foam board.
Plans and Files included!

Bank and Yank Plank

Recently I started work on a prototype fixed wing UAV that for one reason or another never got finished and flown. As a result I found myself with a pair of 1000mm foam board wing panels sat on the shelf. I was going to simply throw them in the bin but curiosity got the better of me and I decided to make a plank instead…

scratch build projects

Mostly foam board creations with a bit of balsa thrown in here and there. These are all the “just for fun” projects that I have built through the years…

FPV Wings

For many years, Red20RC has been synonymous with foam board FPV wing designs. All of my designs are still available to download along with free CAD and STL files for hardware components.

Ultimate KFm6 Wing

I was about to head off on a 9-day tour of Queensland with work and I really wanted a new FPV wing to take with me, so I decided to turn this old KFm6 design into the ULTIMATE KFm6 FPV WING!
Design files included.

PicoWing – Tiny FPV Flying Wing

The NanoWing has been one of my most successful designs to date. I always wanted to see how far I could go with the concept so it was time to try something a little smaller…

Katana X2 KFm6 FPV Wing

After only 3 or 4 flights on the first version of the Katana X I started building another one.
This then is the new an improved Katana X2 KFm6 FPV wing…
This the video and downloads only.

NanoWing Part 2

The KFm4 NanoWing flew so well I wanted to see how far I could go with the FPV race wing design. This then is the obvious evolution…
This is the original article and includes all design files and plans.

NanoWing KFm4 FPV Race Wing

I set out to create a fast race wing that blended the success of the original KFm4 MicroWing with the size of the Turnigy Bonsai. I think I might have succeeded!
This is the original article, video and includes plans and pod files.

Tek-Sumo and SupaBonsai FPV

With the HoobyKing Bonsai FPV wing going so well it was time to step things up a notch. Enter the “SupaBonsai” and Tek-Sumo FPV flying wings…
This article introduces the Red20RC wing pods that were originally sold online. CAD files are included.

MicroWing UAV

The MicroWing UAV was an epic and ongoing project to discover if it is possible to build a small, fully autonomous wing using a KFm wing section and foam board building techniques.
Presented here is the full project article including videos and plans.

KFm4 MicroWing

This project was a spin-off from the KFm6 Flying Wing project. The plan was to design, build and fly a small foam board flying wing based on a KFm airfoil…
Includes flight video and original plans.

KFM6 Flying Wing

The KFm6 Wing was my first FPV wing design and although it never flew with FPV gear it did perform quite well.
Presented here is the original article, video, and full PDF plan and cutting templates.

Bloody Wonderful

by Red20RC | June 9, 2025 | Blog | 0 Comments

In my humble opinion, the Flite Test Bloody Wonder is one of the best RC models ever created. Not because it is super flashy, or aerobatic, or has many features, but because it offers the best fun-per-dollar of anything out there.

To build or not to build…

I was brought up on balsa. To me it is the “proper” way to build model airplanes. But the cost of balsa is starting to make it prohibitive. Is it time for me to embrace the dark side and focus on foam?

So, what’s been happening?

Things have changed quite a bit since the last time I looked at Red20RC. I’ve moved onwards and upwards in the industry but it has shown me that I miss the good old days of building, flying and crashing simple RC aircraft. It’s time to reset the balance and find the best of both worlds.

Return of the Red

I’m not sure what sparked my interest to try to get things moving again, but I’ve decided to try to get Red20RC up and running once more!
