About 2 years ago, I had an interest in using canards as a second set of controls. In combing thru NASA data, Langley wind tunnels I found a Naval Pilot's thesis and spin tunnel video on using canards as ailerons. Limit on deflections is the key.So yes, it can be done.

In thread "Canard setup-help needed" I noticed that F1 quoted "You should never use canards on Roll. Ever" Talked about stall, whatever, but guess what, Canard ailerons , it works!!!

So 2 years ago, I modified "DELTASTORM" to handle 2 motors that pivoted to add in elevator direction, installed 2 servos in the canards to act as elevons, used differential thrust, and this airplane did things I could never do with other. Went so wild that it was dinged. Will rebuild when I get the chance.

While doing test on canards studing AOA using my F-22, decide to re-test and it works, as video shows. I set my radio to 4 modes, no canards,elevator canards,aileron canards and finally elevron canards. Pilot needs to be at least intermediate and needs to have rudder to be very effective. Further testing is needed since plane is touchy.
Throttle curve needs to be lowered and find the max deflection for canards and elevrons.

As you can see it rolls fast, gunning the motor to check stability in different attitudes, it has good speed and descent recovery traits. Winds varied from calm to 8+. Net result, the system works rather well.

Dug up Trickster (Deltastorm) and you can see it wasn't hurt too bad so it shouldn't take too much to put it back togeather. With all the weight of motors,servos, etc. and small wing , it becomes a bit tricker to fly .

Was able to get 2 runs in today. First mistake, I found was throttle curve was set up for an EDF.
Reset it to linear and had much better control of canards. Practiced doing rolls at about 10 ft off the ground in front of me so I will make a video since Greg will probably not believe me.

Another interesting fact is , without any wind, with canards functioning as elevons, a steep approach can be made. Nose up, back off throttle, and a steep approach/landing can be made.
What accounts for this, is the canards do not go past +/- 15 degrees of travel. I now fly with canards on at all times. The other reason this was done if perhaps the VTOL can hover, I was thinking of using canards during the transitional phase if needed.

Next set of tests is based on large deflections of canards to see how acrobatic it gets.
