Hi All,

We have a vario replacing the VSI in our monowheel.  As a vario is just a
faster, more responsive VSI, you can use it in place of the standard VSI.
However, you can not compensate it for total energy, as it will no longer be
a VSI.  Also, it will not be as useful for instrument flying as it will be
more sensitive that you would like.  It will jump around a lot since it does
not have the dampening built in that the typical VSI has.

Happy Building!

Even though have a Monowheel with short wings, i am sure it will still make
a nice glider.
Granted sink rate higher than is desirable for  light thermal, however in a
good long
island convergence soaring is easy, or just gliding should be plenty fun.

Also neat would be to measure sink rate vs speed, precise with windmilling
prop in fine
and course, and stopped prop in fine and course and feather, and also with
flaps. Nice
stuff to know, especial in event of quiet when you don't want quiet.

Later on if aquire glider wings, instrument in place.

Also a bit easier to find and stay in lift if present.

Had a Cessna 170 ragwing for 19 years. Not the greatest glider, had very
small flaps and
was very hard to get prop stopped, but it was great fun. Got over a three
hour flight  on
a good Long Island Convergence lift day.

Europa should be far superior with short wings to Cessna.

I never had to use the magic numbers i aquired gliding round with cessna. If
I lost power,
and was over a few thousand feet, would not hesitate to stop prop, which
would require an
abrupt noseup just before stall to get prop to stop. The benefit of a
stopped prop was
evident in a lower sink rate for a given airspeed, hence a better L/D.

I always slowly reduced power on a step down basis to let motor get cool as
possable to
prevent as much thermal shock as i could. Never saw any indication I hurt
motor.

I imagine the 914 with same care would be pretty happy.
