[rebel-builders] reflex

Post by Walter Klatt » Sun Feb 19, 2012 8:43 pm

Jesse, after I first set up my flaperons, I adjusted the other end, by the
mixer arm, to give me more reflex, and less flaps. I found that with the
Rebel, I really don't need that much flap. I still do all my landings with
1/2 flaps, and only use full flaps on take-off.

BTW, when the flap handle is free, it just goes to neutral in flight. Which
may be a good way to find the true neutral position of your flaperons.

At this point I think I would have to make a new flap handle bracket with
new holes, or else adjust the teleflex cable length but that would sacrifice
the normal down flap travel. It may be a worthwhile experiment though, and I
want to build a better flap handle/mechanism at some point anyway. The issue
is that I set my max reflex so that the flaperon mixer arm hits it's max up
travel...there is no more room there for adjustment. I did that in case the
flap handle lets go so it can only go up so far.
Bobp, I have the same prop as you and I was thinking it was a pretty good
climb prop. I would think a 55 would be too fine for good cruise
performance...especially with a cleaned up airframe. I was planning to
re-pitch to 54 per Walters recommendation once I go to floats though.

Yeah, at 96 knots, reflex should definitely work. You want to reach your
cruise speed before going to reflex, or push down to achieve it as you
apply
reflex. If you have to speed up to cruise in reflex, it might take more
power.

I would play around too, with adjusting your flaperon mechanism to see
what
works best. It makes no sense at all that you don't get any extra speed
with
reflex. With mine it is really noticeable. The odd time I have been
distracted and didn't apply reflex after leveling off in cruise, I noticed
extra fuel flow, to achieve my normal cruise speed, and that would clue me
in immediately to set my reflex.

My cruise speed is around 96 knots indicated and that is where I have
tried
the reflex with no change in IAS or GPS groundspeed that I can see.
Should I try pushing it over to accelerate a bit more before using reflex?

Yes, that is very true. With mine I can slow down as much as 80 mph when
in
reflex, before my nose starts coming up. But if I just go into reflex at
80
from neutral, it doesn't work. You need to go fast enough, probably
closer
to 100 mph, before it really works, and you gain the extra speed.

Also be sure you're not flying on the "step" in the first place. The
Rebel
has two cruise modes, at least in everyone that I've flown. If you just
take
off and level out... you'll be flying on the "step" and slower. I've
found
every Rebel needs to be pushed over the step just like flying floats and
then brought back up to level cruise for top speed. Especially true when
flying in reflex. I definitely get about 3 or 4 knots in Reflex while on
floats. Aircraft loses some of that stable feeling though, so I only do
it
on days without turbulence.
