I flew the plane on Saturday and was very pleased with
the performance. The MVVS 1.60 ran fine and there was no over heating.
It turned an APC 17 x 8 prop at 8000 rpm after less than 3 minutes run
time. This gives the plane good scale looking performance. It is not a
hot rod but it is also not at all marginal. It should pick up a few
hundred
rpm as it breaks in. The plane would not hang on the prop because the
prop
would stall and cavitate losing thrust. You would have to switch to a
lower
pitch if you're into torque rolls. An 18 x 6 Master Airscrew prop would
allow me to "hang" the plane in mid air during nose up testing of the
needle
settings, with my hands just steadying the plane and not holding up any
weight.
Flight is very gentle and
stable. The control throws listed
in the manual would be a good choice for low rates.
Rolls are very axial. Knife edge is very good
and there is almost no roll coupling. All you need to do is roll the
plane
on its side and hold a bit of rudder and it will cross the field in
knife
edge. Stall tests were the same as the smaller version only even
slower.
It doesn't stall and recover, it just flies really slow and sinks a
tiny
bit while turning slightly to the right. The ailerons are still fully
functional.
It will
not tip stall.
It was difficult to get the plane back on the runway in zero wind conditions. It took quite of few go arounds to get it slowed down enough. It would have been much easier if there was some wind to head into. It just wants to keep on flying. People are amazed when they see this. They think it will fall out of the sky like a brick when it slows down. It took a very long low approach to get it down so there was enough runway left to stop. I recommend waiting for a day with a good breeze blowing down the runway for the first flights. This will lower the ground speed, "lengthen" the runway, and keep good airflow over the tail.
A little R2 history:

That's me. Gives you an idea of how big this thing is. Note the big
stakes hammered into the ground.
I'm certainly not interested in getting ground up in that big prop!
