Does anyone have experience with towing a Grob 103 or similar large 2-seat glider with a tow plane in the 160 HP class. Any specific experience details, lessons learned, or recommendations are appreciated. Did you do any testing prior to conducting training? If so, what was executed and logic for a testing progression, for instance. Does anyone propose environmental limits or runway length recommendations?

Asking because our 235 HP Pawnee is going to be offline for a while and we're investigating a lesser-powered Pawnee as a stand-in.

We tow our ASK-21 with our 160 Super Cub. We pull it back a bit more that when we pull with our 180 Pawnee. Both do well enough to be safe.
