I just had the opportunity to maiden a PTS (RTF) for a friend of mine today. We pulled the speed brakes but left the droops on & flaps down.
We had a fun time getting the engine to run. The low speed needle valve was almost 2 turns away from anywhere that would let it run at anything lower than 1/2 throttle.
Once we got the engine running halfway decent it was flying time. There was a 5-10 MPH crosswind which didn't bother my Sig Somethin Extra so I figured we'd be OK. As soon as I hit the throttle the tail popped up & it weather vaned straight into the wind & full right rudder was all but ignored by the plane. It did get airborn & the flight was uneventful from there on but I was absolutely shocked at how difficult it was to take off in a crosswind.
The overall flight characteristics were very graceful & forgiving. I personally felt the control surfaces could have used a little more deflection, but hey it is a trainer.

The landing was extremely graceful right up until touchdown. It greased right in but as soon as it started to slow down that darn crosswind again spun it around like a top. No damage because it was after it was on the ground. just annoying
We did 3 more flights & every single takeoff & landing did the exact same thing. I even went full right rudder prior to gunning it & it shot left (wind was from left) every time. It also spun out on every landing.
So from my intermediate experience opinion it did everything a trainer should do in the air and on approach and landing, but the ground handling was worse than any plane I've ever flown. I was doing some major clinching on every takeoff because we have a row of trees to the left of our runway, I headed straight at them every time. [X(]
I know what you mean about "ground handling" I have mine since last Sept 2005 and most of the time it still does the same thing you explained, got to figure out what is the cause I did change the rear landing wheel, and moved the antenna to the horizontal stab, because one time on landing the ant. was wrapped around the axle and wheel.
Someone must know how to correct this.
