All of these planes are EPO and with the exception of the Wildcat the wing spans range from 66" thru 82"
The gray foam Corsair was cut from B Taylor plans .
Contest can find a reason to exclude or include any type of plane. With creativity some events get the kids involved with the elfight tiny line of planes and fail safe systems, all good for the hobby and the people in attendance.
It really depend on the event you want to enter.
Persoanlly I have been building wood glass and foam and with my recent club I found that some of the oldest most traditional members are in total awe of foam and how they fly. Most are beyond the point of wanting a 30 lb warbird so a 79" P40 that comes in at 15 lbs is a total joy to fly .
Both my P40ties are 79", full scratch built interiors, full powered Fergelli canopy servos, animated pilots tied to alierons and elevator and the club member get a total kick out of seeing them fly. Scale props, cool sounds and simple plug and play .
So find a contest that will allow you to fly what you actualy enjoy and don't compromise
