When I was 12 or 13 I built a 72 inch Cub with a Veco .19 free flight I used to haul on my bike. All was OK unless the wind came up. I had the wing running along the cross bar and the fuse on my back. Any cross wind and it tried to move the bike. I have had the fuel leak and get the paper bag wet and all my stuff fall out. Those old 1 1/2 volt dry cells were heavy. I could have put a basket on my bike but then I would have gotten into fights for not being cool. Baskets and ape hangers didn't go well together. Life was better when my dad would haul me out to the dam and pick me up later in the day. Then I could take several planes and do free flight in the morning and U-control in the afternoon. Once in a while Clarence Lee would teach us kids how to tune and engine and answer questions for us. Watching all the RC planes crash was high humor. More crashed then flew back then. We have it really easy these days.
