Does Anyone Fly a Plank ?

I have a Ft Millennium Flerken that i still have to fly...I will let you know how easy it is...One challenge that I find with wings is that you can lose orientation pretty easily.
I assume you are referring to a flat wing, no airfoil.
It has been tried. It will fly, just not very well, it's very draggy, poor glide slope. If you want an easy build, look at Kf airfoils. They are a big improvement over a plank wing.
The Kf wing is a bit easier to build than the Flite Test wing. But the FT wing has a far better glide slope, well worth the extra effort.

Hi Merv,
Thank you for the idea. I think you will like this. I have built a 3 step KF wing. It measures 30" x 11" including 12" x 2" aileron. The KF wing was part of my plan. I don't have a KF wing plane. So I thought it was time to build one. Next I need to build the fuselage. I am thinking the fuselage is going to be 20" x 2" with a FT power pod.
Open to ideas,

Yes, if you design one, a single plank will work. Suggest you get some experience with a FT model to get the feeling of a wing. One of the problems is if you go out to far, the beginner looses the shape(no fuse) and before they know it, it spirals down.
They are also fast and can be used to be modified for speed runs.

These are designed with no rudder and even work with an EZ Pack 2 and handle gusts very well. That's increases the flight time for the EDF having a 3S 1300 battery to over 10 min.

A "plank" is generally a flying wing with very limited or no wing sweep. It is called a "plank" because the wing is a long rectangular shape like a plank. Plank in this context has nothing to do with the airfoil but instead the airplane layout. Just like any plane you could build it with a bad airfoil or build it with a good airfoil. Some planks have vertical stabilizers and some don't, but a plank can't have a tail with an elevator as it is a flying wing.
This is very different from a flat plate plane like a FT-Nutball or flying stop sign for example. It is also not a V shaped flying wing like the FT-Arrow.
Here is an example a "plank":

I have build and flown lots of planks.
They are fun but I would not recommend them as a first or second plane.
First plane: High wing trainer plane with an elevator in the tail
Second plane: V shaped flying wing, FT-Arrow for example
Third plane: Plank
Flying difficulty is about the same as an FT-Arrow or other V shaped flying wing. However a V shaped flying wing will take less damage in a nose first crash.
Drawbacks: Has a nose to get crushed in a crash, like all flying wings the CG location and control throws are much less forgiving than a tailed plane, like all flying wings new pilots can loose visual orientation because of the lack of a large tail and long fuselage.
