The_Storm,
Sorry to hear that, but family does come first. Hope your son get well soon and see you on the race course some day.
I'm in similar shoes as you. Although, my little baby girl is very healthy indeed. The only exception is time. No time to build, fly or get away to bigger races other then our local races. But plenty of time spent with her, which is good. Hopefully, daddy can bring her along when she's big enough to run around, and be my little pit crews.
Fair well, my fellow Pylon racer brethren... We'll see you again someday.
