Dennis,
Maybe it's my SUPERIOR piloting skills that keeps mine from going in!

THat and the fact that they keep the bleachers behind me when I am flying the BC.
I haven't got the book in front of me right now (nor do I remeber my college physics) but there is a direct correlation between the length of a lever arm and the force that is required to move it, or rotate it as is the case here. Stronger servos is not necessarily the cure for a poorly setup linkage. In my opinion I have proven time and tiem again that the servos on mine with the linkage setup correctly is more than sufficient.
Here's a picture of my linkage.
