Just curious about the P-51 FM

If your models are scale right down to the airfoil curves then there's a little problem right there.

It just took me 10 minutes to remember the name that goes with it, it's about the Reynolds number which changes for wings as they get bigger or smaller.

The same shape airfoil works differently with different scale wings. What worked great for a bird worked less well for airplanes made before 1920 though the Gottingen thick wing used on the Fokker DrI and DVII went a good ways to fix that. Going from about 10 meter spread down to about 2 meters is going to be subject to a measure of that. But -only- if the curve of the wing is kept to scale.

I am wondering about controls on your models. Are the rudder, elevator and ailerons all controllable? I know of smaller models that only do rudder and elevator.

I also wonder if your controls are channel per axis direct like was done since long ago or if it's one channel wireless computer communication with a microcontroller in the plane? There's pluses and minuses either way.
