RE: Engine / Prop Vibration
BTW, the button balancer is good for rejecting props. I use a better one down in the shop, one that'd be a pita to carry in the car.
Also, btw........
The LHS that didn't want me to check their props with my button deal............
They have a display with a magnetic balancer that sits over the prop bins. I use that.... grin...... when they're not looking of course.
And about that display they have..........
They have a prop in it 24/7. The prop they chose was "perfectly balanced" (their words). The reason they think it's perfectly balanced is because it will INSTANTLY whip around to horizontal as soon as you let it go. The sucker is so far out of balance that when the hobby shop door opens and a breeze whips in and turns the prop, the prop almost won't turn. And will return to horizontal in a heartbeat. chuckle...... some people really don't have a talent for their chosen profession.
