so I have a World Models 57" ws P-40. she's fast. and lands fast, anyone know if flaperons would work on this plane?

if this helps, you can see in the Pic. the Ailerons are 4 inches from the Fuselage.

thanks guys.

It could induce a tip stall. Might have better luck using a lower pitch prop to slow down the landings.

Hard no.

If you want to try anything you might want to create some crow and reflex the ailerons up a few mm like we do on jets but definitely don't want to lower them.

OK, thanks guys, big help there.

A) less pitch;
yes, I was told that at the field. the last flights I had an APC 11x8 on it. I am going up to a 12x6x3. I have not had it in the air yet with the 3 blade. my engine is the OS Hyper 50sx with the large 60L Heli Carb. the Head is the older Heli "Heatsink" head that I turned down on a lathe. I have a GMS 47 over size muffler on it. with the Heli Carb it turns 900rpm over the plane Carb, so I am not going to worry about the RPM drop with the larger 12x6x3.

2) reflex the ailerons.
yes, I remember now, I read about that way back. I will try that, thanks for reminding me.

I've has that set up on a couple planes, plane didn't do anything crazy just with flaperons you end up very mushy aileron authority

So if you try it,, just make sure you also mix in more aileron travel to make up for the mushy ailerons

I routinely mix aileron reflex on most of my planes, whether they have flaps or not. It adds desirable drag and delays tip stall. Somewhere between 20 to 45 degrees depending on aircraft type. Put it on a slider as opposed to a switch so you can vary the amount of throw from your transmitter.

You can read up on this technique in the glider/sailplane columns of Model Aviation. It's a proven technique.

Best of luck.
