1st and 2nd planes
I know I'll get a lot of different answers on this, but in reality what makes a plane a 1st aileron plane and what makes one a 2nd aileron plane? For example what makes a Parkflyers BeginAir a 1st aileron plane and what a 4 channel warbird a 2nd aileron (if you think it's one) other than how it handles and the fact the warbird would probably go a bit faster than something like the BeginAir.
