[rebel-builders] Landing speed and Thank you to Si Smith

Post by Ken » Sun Feb 19, 2012 5:33 pm

Hi Keith

We've seen Si's plane and agree that it is a "rocket"!

FWIW my rudder (and elevator) is very light to move but I do have two
pulleys on each of the four cables. Without the pulleys I've noticed
that you can hear the rudder cables moving through the guides which must
add some friction.

I normally approach at 60 to 65 knots. For a very short stop I'll come
back as low as 50 over the threshold as long as I have some power on and
flaps but that would NOT be a recommended thing. The caution (as you
will discover) is that when you get this wing behind the power curve, it
will just sink instead of flaring. I generally like to keep a little
power on until I'm certain I've flared and am not descending. Even in
ground effect, there is often only a second or two between a level
attitude and the 3 point attitude with power off. I would not like to
experience a power loss if below about 65 knots with this airplane. No
problem above 65 knots though. With power off you almost have to
consciously push it down through the last 50 feet to keep the speed from
decaying. Weight affects all of this by a few knots. Anyway there's one
opinion for you. No doubt there will be others ;)

my O-235 powered 7AC in the tour and compared to it the Rebel feels
like a sports car as far as the stick goes. I did notice though that
the rudders were MUCH harder than on my Champ. Is this typical? I am
not saying it was bad....just seems like the stick and the rudder
pedals are at very opposite extremes of force needed to move them. I
really liked the climb also. Seemed to climb like a rocket compared
to my 127 and Champ. Now to my main question....What speeds are most
of you landing at? Maybe I am just used to the Champ but we seemed to
land a lot faster in the Rebel than I normally land in my "Super
Champ". I was very pleased with Si's Rebel....Very nice looking and
performing plane. Again Si, thank you for the ride and experience.
Sorry I didn't say goodbye before I left but I was not feeling well
all day and needed to go home.

Keith
Once you get used to it the landing distances can be pretty short.
It is just that it has bitten several guys that weren't prepared for the
sink at low speeds. I foolishly usually turn off at the entrance ramp
when landing on 06 at Brampton. I don't think that is more than 200 feet
but there isn't much room for error when doing that and I have that
geared EFI soob which has never missed a beat in 300 hours as well as
previous STOL experience.

Ken,

Thanks for the info. I guess I was a little "dissapointed" in the landing speed. I fly mostly out of short strips and the speed makes a big difference on these short strips. I guesss I was looking for better slow speed ability. Always wanted a Super Cub but they are WAY over priced for what you get.
Si had mentioned that his sons Rebel was using pulleys and the rudder was much less hard.

Hi Keith,
Your welcome but remember a few things there were 2 of us and 40 gal.
of fuel on board,, I had only made 3 landings at that strip before ours, and
I was not familiar with the effect of the quartering cross wind over the
trees. I get in to my home airport quite a bit slower with flaps and power
but as Ken said with that kind of an approach you better be ready to land
when the Rebel is but it will land shorter. David says his strip is 1800
feet and we were stopped at a little over the half way point. The last
glance at the airspeed I saw 65 MPH and didn't want to get much slower than
that at that strip and my knowledge of the strip. I hope we can get together
again for a little more time in it. Hope your feeling better and it was a
great weekend.

Si

[rebel-builders] Landing speed and Thank you to Si Smith

Post by james.smith » Sun Feb 19, 2012 5:33 pm

Keith,

As Dad mentioned to you, the rudder control forces on my Rebel are much
lighter than Dad's. My Rebel is running 2 guides and 2 pulleys so that
probably has an impact. Also, I'm running a small tailwheel (not Murphy's)
and Dad is running a Scott 3200 so that is also a factor in the feel I'm sure.
Whatever the specific reason is, the difference is dramatic and was basically
the first comment that myself, Matt and Dad had after flying my Rebel was
the difference in the feel of the rudder. I have about 1/2 dozen landings on
pavement with the 26" Goodyears and I think the rudder forces are probably
a little too light. You really have to be on your toes.

As for landing distances (and take off distances for that matter) we're pretty
strong believers that the limiting factor in the real short performance of the
Rebel is limited by the angle of attack. Dad's Rebel with the 800 X 6 tires and
spring gear just doesn't have enough angle of attack to take full advantage
of his performance potential. The 26" Goodyears seem to be a good fit so
far. We only have about 13 hours on my now since the rebuild was
completed so we're still working through performance. The only down side to
the bigger tires so far is that gear shakes pretty good after you break groung
and the gear starts vibrating once you get over about 115 MPH. It really is a
nice flying plane though. I was hoping to bring it to Fall Colors but with my
wife due with our 2nd child in 2 weeks and some issues I have going on at
work, I just couldn't justify taking off for a couple of days.

Hope to get up your way in the next year for sure.

James

PS - the comments regarding flying slow approaches behind the power curve
are right on. You can't fly the approach in the Rebel like the Cub or Champ.
Once you get it slowed down you really have to be ready for the bottom to
fall out. Just like any airplane, after a few hours you'll have it down. I don't
know if Dad told you or not, but on about landing #5 after the rebuild I had
mine down and stopped in 300 ft. Granted this was on our favorite runway at
our home airport that has an open approach over a cornfield (and I had the
mains in the corn!) so operating in and out of your strip just won't be an
issue.

Thanks for the feedback James. If your Rebel is even half as nice as your dads it will be a nice Rebel.:)
