RE: What is the function of crow?
Don....I doubt anyone can reasonably argue against your point. However as a famous baseball player once said "the game is 90% mental and 50% physical"...point being that flying model jets is a head game as much as anything. If you "believe" you have a engine that will never flame out you will fly more daring manuvers, if you believe your radio link is as solid as it can possibly be the thought of loss of control never enters your mind, and if you believe that crow let's you land slower without a worry of dropping a wing then you WILL land slower without the stress of thinking she is gonna depart any second. I think we all agree that most of us land at speeds much higher than we need to anyway.
As I tell my guys at work all the time. Perception IS reaility, and that is a fact.
