To prevent wing drop in Libelles:

Longer tow rope. 250-300 feet works well.

Start with open divebrakes on the 201 during the initial roll. But, be
very careful here. The Libelle's brakes aren't very powerful which makes
a brakes open on tow problem especially insidious. If they are open
after lift off, the tug driver probably won't notice immediately. You
will be way down the runway when you and the tuggy realize that
something is wrong. Take it from one who knows ; )!

Use negative flap on the 301. Works even better than opening the
divebrakes on the 201 and doesn't have the inherent hazard of open
brakes on tow.

Stick full forward from the beginning of the takeoff roll until the tail
comes up. This will get you aileron authority as quickly as possible.

My 301 has Kestrel landing gear which is even taller than the original
301 gear. This makes for an even greater potential for wing drop. Using
the above techniques, I rarely ever have a wing drop, even when being
towed by weak tugs.
