Well it was forcast (as I was driving to the field), 20 gusting to 28, which
was great because I got to test out the FC in the wind. OK, now I know what
Mike and Andy were talking about the little strip they put on the rudder.
The plane was very sensitive in the wind and seemed to get bumped around
quite a bit. The theory is if one puts a 1/8 strip on the TE of the rudder,
it damps out the yaw. After working hard at the sticks, and increasing the
expo to about 30% on aileron, elevator and about 45% on rudder, it seemed to
settle down a bunch.
I also went to a smaller prop, 30x12, that seemed to help the snaps some,
and then went with 10% additional aileron, 20% less rudder throw on low
rate, and a little less rudder to opposite aileron mix. This seemed to do
the trick so it does acceptable positive snaps to the right. Negative snaps
are even better too. Guys, thanks for the advice on this.
The smaller prop also helped with 3D and torque rolling. now its 4 to 5
clicks to hover, which turns out to be about one-fifth to quarter throttle.
But throttle resolution is much better (damped), I can move up or down at
least a couple of extra clicks to maneuver the plane. Noticed a lot of left
rudder needed when transitioning from high alpha to hover. May have just
been the wind. I think it calmed down to about 5 to 7 mph on the ground by
this point of the day.
Now I'll save the best for last. I ran the plane out of gas on the last
couple of flights. After the engine quit I did several pop ups and upright
elevators and back to regular (gliding) with almost no transition. The
plane is so light I think you could probably almost 3D it all the way to the
runway the push the nose down, flair and land. It really opens up some
possibilities. Dead-stick 3D, wow.
Thats it for now,
