KR> Cracked spar

[captl...@aol.com]

The radiator is in the rear of the fuselage with an inlet in the belly like  
a P51. The weight and balance came out great running from 8 to 12 inches from  
the leading edge. I was just wondering if I could run something like 1" by 4" 
 douglas fir, spruce or possibly plywood along the front and rear of the  
spar to regain or possibly improve the strength of it?
Thanks Don
