Default RE: phoenix decathlon

The dual rate on the rudder is really a good deal. When it is slowing on landing and the tail starts down, I've found that I really better be in high rate for rudder. If the wheel pants hit any high grass, the low rate rudder won't stop the ground loop. Once it's speed is bled off, it doesn't matter what rate.

I think when it's attitude is on it's three wheels, the wing much screw up the air enough that the fin/rudder isn't producing enough yaw stability. And until the fin/rudder has enough clean air at enough speed, it still won't have enough yaw stability to counteract engine torque. And the rudder isn't working worth spit.

Most of my takeoffs are at about half throttle. But so far, every time it's rolled a secord or more with the tail up, she'll take any throttle advance like a sweetheart. I've yet to TRY to jam it full to see if the torque will roll/snap it into the runway, but who would? However, I don't try to ease it any more once it's off the ground. I think that when the wing is flying the fin/rudder is way into it's safe speed envelope.

BTW, wait till you try to knife edge the honey. Then you'll see just how powerful that rudder is. She really knows she's got a rudder. And rudder couples.

But nothing vicious.
