RE: Retention Rate
Couldn't agree more Steve.
I am the local grump who has burned out over the years trying to help some youngsters. It can take up your flying day fixing their half baked assembly while they are off yakety yaking with other flyers. Of course they want to do 3D right away (and have the quickness and co-ordination to do it) but not the aerodynamic (nor safety) knowledge/judgement, hence the "duck and run" entertainment.
If they last the season and return next year I am more inclined to take them seriously. Until then, the club instructors can deal with them.
