TRY to let her pivk from a LIST of known good planes. She needs to get that I am deciding to actually pick and fly feeling. A list of good planes from the club instructors would make you a VERY supportive guy and shift any problems to the instructor.
Telling her You want her to succede with her OWN plane is KEY.
Get the club inspector to check out the plane & OK it.
Do you see a trend here ???
You are supporting her everystep. But will NOT be the bad guy when there is a KERBOOM.

"" You really care so much about my learning to fly, that only the most experienced people will do ? ""

Yes.

"Sweet man."
