[rebel-builders] Max flaps

[N.Smith]

Hi Jesse

Be very careful doing that - the flap attach points on the rear spar of the
wing will only take so much load, not sure how much (if any) spare you may
have to play with !!

I'm in the process of rebuilding my flap handle, and considering increasing
the max flap setting. I would severely restrict the airspeed for the last
notch. Has anyone done this who could share their experience?
Thanks

I don’t know how much flap you have now, but between reflex and flap, you are limited by the mixer box. I have mine set to get the max reflex that I want, and the rest is flap. For landings, I never use more than half flap anyway, land or water, and heavily loaded. I only use full flap for take-offs.

The only time I ever used full flap on landings was back when I was on wheels and flew in sometimes to an ultralight field, and then would drag it in with power and full flaps. Could get it very slow and short if I wanted to. But on regular landings, half flap works just fine and still lots of control for winds and gusts, esp with VGs.

I believe getting max reflex is more important than max flaps. JMHO.

I would not want to mess with MAM's 18
degrees max warning. I'm finding that the only time max flaperon makes
much difference is hot heavy takeoffs from water (pulling the nose
higher increases float drag when you are on the step). That is the only
time I would consider using it even if I had more flaperon available. On
land I've found that the difference between one notch and 3 notches (18
degrees) of flaperon is not nearly as significant to takeoff, obstable
clearance, and landing distance, as I once thought. Of course I do like
to sideslip :) Other Rebels may be different.

Besides - is there anyone here who has NEVER oversped a flap?

I never use FULL flaps as it is because the controls get too heavy.
I cannot imagine another notch.

Add VG's they will lower your stall 8mph--If thats not enough add some
Zenair slats. You should be able to fly around then at 30 mph.

As Nigel suggests be careful playing with too much flap with only two
hangers/per holding them on.

I'm assuming you're running the full length flaperons Jesse.. as that's how
I sold that kit to you. I've always had mine going to 21 degrees... as full
flap... and mine are completely covered in aluminum which adds a bit of
structural strength to the spans and has never been an issue that I've seen
or noted during inspections.... but I sure wouldn't go any further than that
as there is no considerable differential when they are down full. You can
NOT turn with stick at full flaperon down.. you have to use your feet and
point it where you wanna be.

Walter, If I use the second notch of reflex I lose the smoothness and additional knots I get with the first. CW

I am sure there is a limit as to how much reflex is beneficial. I have mine
set so it maximizes my speed at full reflex (increases speed about 5 - 7
mph) and lowers my fuel consumption (.5 gph difference to maintain same
speed). My controls do stiffen up a bit at full reflex, but it doesn't take
much movement with your fingers to affect roll, so doesn't really matter
while in cruise. When I am doing steep banks (usually when trying to get
down into an alpine lake), I am going much slower, and would not be in
reflex anyway.

Like I said, there is a trade-off between reflex and flap travel in your
mixer box. I just set mine to utilize the most beneficial reflex, and then
use the rest for flap. In your case, Craig, you might have too much reflex,
and be short on flap travel.
