If the bottom blade stops turning, or looses too much power, it
should start to fall immediately unless stuck in the ceiling. The
problem is when the top rotor is stuck or wedged or whatever and not
turning while the bottom one is turning is this legit? There seems to
quite a difference of opinion as to whether this is an advantage. To
me, (watching this happen up to as much as 30 or 40 seconds in
practice) it seems as if the other rotor is not doubling its' speed
which it should (must) do to produce a fair motor run and flight.
Probably the ten second rule should be applied. It has worked well
for lots of years.
