Billy, You have really made progress on your Baby! I still like building the wings. About the tail wheel spring, I'm going to have the 4340-E heat treated. Did you buy parts from Replicraft? I'm still waiting for the axle to be finished. Kinda got burned out building ribs for the wings so I took a break for a while. I started working on a 1/3 Scale J-3 Cub from Balsa USA. 141-1/2" wing span. It's in the bones stage now ready for covering. Takes a 2-4 CU IN ingine. Billy, are you in the music business? I'm a drummer from the 70's and 80's country, rock, and a little bluegrass. And a lot of water has gone under the bridge. If you find a time that you will be free, let me know and I'll drive down. I live in Cosby TN. about 35 miles NE of Gatlinberg. Steze
