You are welcome. If your Acro doesn't already have the Z tape
installed, I would be interested to hear your opinion as to if the
efficacy of the rudder is noticeably improved (or not) after the
installation. If the fin airfoil profiles of the Twin Astir and the
Acro are close, I suspect that you will notice a favorable improvement.

I finally checked our Acro II last Sunday: as I thought there's no fin
turbulation on it, so I've passed your reference to the Lindner TN to the
relevent club committee member.

It turns out that our Acro now has a fairly low cockpit weight capacity.
On Sunday we were using it for trial flights but we had to temporarily
take one of our ASK-21s off scheduled training duties to fly a reasonably
heavy trial flighter. Some of our members would like to use it for mutual
XC flying since its a better XC glider than an ASK-21 and has a decent
SDI flight computer fitted. That said, our ASK-21s do routinely go XC on
good days with students who are close to soloing - an 80km o/r to HusBos
is favourite with our paid instructors.
