Cox PT-19 was the first. For my next birthday, Cox Stuka in green,(I have been told they didn't make them in green,HA) 1/2 of 1 lap and hit the deck. Exploded. Dad said he was sorry. For the rest of my c/l career, Lil Satan's. It's amazing what you do learn without prompting. The older kids showed me how to resolder tanks that cracked, cutting ribs from ink printed wood, Ambroid takes time to cure,and finding "dope" make the head feel funny.
