Same here Phil. I found not being as aggressive at first would help. At some point
my kids decided to play with it, luckily if have an AOA but the occurrences
did drop. Also if you start riding on the mains with the nose gear off the ground
slightly on t/o you won't get the horn as it will lift off when ready.
My 2 cents.

No I have not experienced that, not even doing soft field takeoffs
(practice, don=99t fly in and out of soft fields).

I don't remember if the plans called for slotting the mounting of the
vane. On all production planes with that type of vane, the screws allow
adjustment of the vane up or down, which changes at what speed the vane
activates.
You didn't say what amount of flaps you are using, -3, 0 or 15 for
takeoff..which will significantly change stall speed.
I used to have my AOA squawk occasionally on rotation. I think I just
increased rotation to 65-70. I use 15 degrees flaps for most takeoffs. I
enjoy the elevator ride up for the first 500 ft until I get flaps
retracted.

The only change I made from the plans was to place two fuel filters one under each
seat and a shutoff in the wing root.If debris clog one filter the second filter
provides a source of fuel.The first 10 I built had the filter in the standard
location and after the wrestling match of the first annual there was a seep
that was finaly resolved with a bonnaco hose.An FAA inspector discussed with
me a fatal crash he had investigated (not an RV] caused by a clogged automotive
fuel filter.As a side note after 10 annuals I have never found significant
debris in the main filters although the fuel injection filter had some debris
.

I too have found that cleaning the std filter is a pain. I have gone to doing a
timed fuel flow to tell if the filter has lost any capacity. Way easier to do.

big job to deconstruct the fuel manifold and inspect the filter. I would secure
another source for my fuel unless you have no option and then I would filter
it through a chamois like they do in Mexico or get your own filter. If need
be dispense the fuel into cans and then filter it.

I think your initial rotation is at a higher angle of attack than any other time
in your flight.
Bending it more would change something, so start with that. That is how I got mine
to beep at the right speed.

Armchair quarterback here .....
My analysis of the original post is that at rotation the aircraft is
still moving parallel to the runway and at a high angle of attack .....
hence the beep which is short because the relative wind changes.
I've become used to aircraft that gives you two warnings before the
stall, the first is a change in noise as the wing skins suffer from the
detaching laminar flow and then the stall warning prior to a true stall.
The vane on Van's stall switch is easily bent, either up or down, and
I've had to reposition mine because it's been bumped during building. I
wasn't going to install the switch but then what do you do with the hole
in the leading edge? So it's there and is wired. That may change if I
find it's useless to me.
So, go gather some stall speed data and tweak the vane. Up to blow the
horn at a lower airspeed, down for higher (I think) ;-).

I was going to fly it again this afternoon but the winds are a little more
than I want to take on this early in Phase 1. Maybe this evening.
The configuration is Flaps 0.
The technique has been to roll down the run way until 65 KIAS and then ease
back to fly.
The aircraft is nowhere near stalling, despite the brief beep of the horn.
To this point, I've only stalled it in the full-flaps position. Stalls at
55 and the horn begins about 60. I'll have to try it again in a Flaps 0
position. But I haven't wanted to spend a lot of time at low power
settings unless its absolutely necessary until the engine gets further into
the break-in process.
The stall warning horn does appear to be perfect for full flaps though.
When landing with flaps 30, just as I pull the nose up to really get into
the flare, it blows and then the wheels squeak in. It doesn't mean it
can't be tweaked more though.
My thought is that, as pressure built under the wing with airspeed (IE:
ground effect) that the bubble was sucked up around the leading edge
briefly as the angle increased and the stall warning vane was just in the
way. But then again, there's no buffet, it's solid.
Next step is to try the recommended technique of full aft, ride the mains
as long as possible, and then let it fly off. I'll follow that with stall
test later on in in the T/O configuration.
Thanks for the advice. There's a few things here I can improve on with
technique and also a few test I can perform on the plane.
Hoping to go again this evening if the winds settle down a bit more.

Hi
FWIW I put my fuel filters n the wing roots. I did at one point have them under
the seats. Under the seats is just a little less inconvenient than the tunnel.
Even though I put an access panel in the tunnel, I wanted to be able to inspect
the filters quickly and easily. All I need do now is to remove the top root
cover and the filters are out in a couple of minutes.
I also wanted to minimize connections inside the cockpit and near the exhaust.
I used Earls Performance fuel filters which have worked out quite well. The filters
screens are easily removed and cleaned.
Cheers
