Moose approach speed; STOL performance
Posted: Sat Feb 18, 2012 9:54 am
I'm still experimenting on approach speeds, but, about 70 carrying a bit
of power seems to be my current sweet spot. On a power-off approach I
have to hold almost 80 or there is no elevator left for flair. At 70,
when I pull the power over the runway, it drops big time--one has to be
ready to touch down or else.
I'm sure I could get it shorter than ~ 1,200' if I used brake with the
70 approach speed. The problem there is that I have to have a lot of
oil (weight) in the baggage area or, upon touchdown, using brakes makes
it really, really prone to want to tip up on the nose. Full aft stick
and a feather-touch on the brakes is the best I've done so far. In
other words, practicing short landings solo is really not a valid test;
the plane just handles much differently with a full load.
With a lot of time in a Maule, it was much different. The Maule didn't
have near the useful load so I didn't see that much difference in ground
handling when solo. The Moose has such a large useful load that there
is a big difference between solo and loaded ground handling. I'm no
expert, but that is my strong impression anyway. The Moose is built to
haul a load; not to land like a super cub or Maule, in my humble
opinion.
I don't like to drag a plane in on final just to enable a shorter
landing; if you lose the engine you're toast.

I am told by another Moose owner that if you go too slow, I think
arountd
65mph on final that the tail wants to sink and there is nothing you can
do
about it. He did the M14 radial prior to Mam so maybe the c of g is
different. Is yours a Mam conversion? Or is the horizontal stab too
small.
He said it prevented him from doing stol landings. Any comments.

clevisI don't know about the Rebel, but, when I put a lot of baggage (re
camping equipment and food) plus my wife and kids in my Moose, I have
to have nearly full forward trim.
I try to have 1/2 aft trim for landing. I want to be able to do a
go-around without having to use both (weak) arms on the stick trying
to keep it from going vertical <grin> with full power.

I got my trim servo installed with nutplates and the pushrod all
fitted. I only drilled one hole in the horn, right at the end. As
currently adjusted,
anticipating a need for more nose up trim than nose down, I have about
1" of
trim tab down throw at the trailing edge, and about 5/8" up. Will this
be
enough, or do I need to drill another hole further down the horn?
Problem is
that I had to "scallop" out the edge of the horn quite a bit for
clearance so if I make another hole it will have to be quite far down.
Thanks Jesse
