Rockwell P-51
You were right there is a -46 model and it's wingspan is supposed to be 53 inches. I just got through remeasuring the wing span on my plane, there is some dihedral<sp> in the wing so I measured the wing from the top and the bottom 43 and 1/8th from the top and 43 and 1/2 from the bottom.
Would someone that has the the -46 p51 please measure there wing span and shoot me a note or post here there wing span.
I am hopeing to find the manufacturer of this plane so I can order a wing kit.
thx for your time and effort !!
