| Barry,
This reminds me of a time about 35-40 years ago when my father made a rubber powered model for my brother and myself. We took it to a field and had a thoroughly enjoyable afternoon flying it but couldn't work out why the plane did a beautiful circle round the circumference of the field and came back to us every time. We even got the hang of how many turns on the motor was required to get the plane to almost land at our feet and the challenge became to get it to return as close as possible to us on the ground.
It wasn't until we broke it down to put it back in the car that we realised we had counted the wing frames incorrectly and offset the wing, held on by elastic, by a half a frame width. This taught us an invaluable lesson that we used after that to determine the radius of the arc the plane would fly to best suit the field we were in at the time.
It is remembering little gems like that that make me sad that I havent got any kids to pass them on to.
If anyone has any spare kids they can lend me for Sunday mornings I'm your man!!
Maybe that is why I enjoy the forum so much! |
