Dear fellow 601 Builders/Flyers, I may be hijacking this, but is anyone familiar with some posts a couple years ago involving adjusting ailerons down a bit? I seem to remember several flyers were experimenting with drooping them a tad for better control or performance or some reason. Who out there did this and what was the results? For the last year since I stretched my cables in a crosswind balloon landing my XL seems more "twitchy" in climb to TOC. Maybe the ailerons are too high or too tightly adjusted? Hope to hear from some builder/flyers. Thanks, Bill of Georgia

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Bill, are you sure you stretched your cables? As I recall, they have about a 900 pounds-plus capability, which ought to bend structure before breaking. Doesn't seem like a nasty landing ought to do that.

Bill, On my 601HDS, I placed a dial type level on top of the top
longeron on the side of the cockpit. I originally found I was flying 2
degrees nose high at level normal cruise. I started drooping both
ailerons a 1/2 turn at a time. ( I thought I had them neutral, eyeball
of course) At zero on the level, I picked up _4 MPH_ at cruise. At
negative angles, I again lost speed. I did not detect any change on
control sensitivity at any setting.

Leo, thanks for the info. I don't notice the "twitchy" effect in moderate climb (say 500 fpm or less), level flight or decent. Only on initial climb out, max power, nose up scratching for altitude accent. Usually, 1K fpm + (at) 100 mph or better. I know the nose up configuration is decreasing stability, but my AOA LRI is buried in the green so I'm nowhere near a stall. Bill
