all of that are big enuff to hold an .049 COX motor... Long as the bellcrank is in the right place they fly great... The by planes are fun because you can't hardly get em to dive or fly close to the ground, and that durned little red tri-plane... whew!
All the low wing 400 series planes are excellent 1/2a fliers... The 1000 series plane work great too, and long as you keep em a little lite... AND BEEF UP THE LANDING GEAR.
