motorgliders as towplanes

K13s and Bocians (both types I fly regularly) also aerotow in a noticeably
nose down attitude. The Bocian is such a slow glider that it unlikely that
any normal tug could fly slowly enough to get close to its stalling speed,
without stalling itself, but the K13 definitely starts 'wallowing' below
about 52knots, whereas its normal free flight stalling speed is about
36knots.

I also noted, in the case of a 2-33 and a Blanik L-13 (the crap that I
usually have to fly) that BOTH of these gliders fly NOTICIBLY nose down
on
tow! (which menas the rope is imparting a nose up force vector, even in
normal, tow position. )

Anyone who has flow a 2-33 knows that it takes CONSIDERABLE forward
stick
force when on tow.

I have experienced the "too slow tow" phenomonon in the '33. (never
got a too-slow in the Blanik)

Again, my point being that I am still not convinced that anyone has
completly explained the phenomonon, that we all agree exists!

forward and downward pull (relative) to the glider! =A0

I'd expect high tow to give a downwards pull and low tow to give an
upwards one.


Seems a lot to me as well. What are these people towing with - chain?
