We use a Falke with Rotax 80 hp engine here in Wesel / Germany.
We tow in Wesel i.e ASW19B / LS4 / St.Libelle / Janus C / ASK21.
I am just a glider pilot, but have been pulled up by the Falke several
times.

The best one can say is, it works and it is cheap. But it is really no
fun. I would always prefer a 180hp tug like Remo DR300 flying with
110-120 km/h.

The Falke is flying before the glider takes off.
There is no extra speed, the tugplane flies with about 90-95 km/h, so
if the Falke comes into strong thermal and is lifted, you have no extra
speed to pull up and follow, so you will feel the prop blast.
If he leaves the thermal you will get above him. If you push to follow,
be sure not to overtake him.
If you are circling while tugging be sure you are on the outerside of
the circlediameter, because the Falke is flying with 90 km/h and you
are on the inner side, you will get to slow.
If you have no wind, high temperature, a heavy glider (Twin I) or the
ground is wet and soft, you should better leave it.

If you have a glider that likes to drop a wing, you have disadvantage
because accelaration is very poor and the time when your wing holder
has to finish his run and the time where your rudders are working can
be very long.

Yes it works, but be carefull.
