QUOTE=Sam Buchanan;1725019]Deflect one aileron full down, drop the flaps to get as close as possible to matching it and you will be very close to 20 degrees. It will also be a good setting for short field departures. No need to get more precise than this.
Help me Sam and Mel.
RV6 Ailerons are set to 15-17 deg. down as measured with a level on the top skin. This is shown in the Manual, along with physical measurements through the chord.
There are no instructions I can find to equate degrees measured on the top of the Flap skin. I was always taught that Flap degrees are set through the chord using the tooling holes. If this is wrong, you are correct Sam. 15-17, close enough. If it isn’t, flaps set to the down aileron would be more like 12 deg., through the chord.
I just measured my Ailerons. I have exactly 15 down and 30 up.
I measured my flaps also, through the tooling holes, and I have 38 down max.
So,….. where are we putting the digital level on the Flaps?
If it’s the top skin, my flaps are 45. with no chance of the upper skin being anywhere close to popping out over the wing.
This doesn’t make sense. I shouldn’t get that much travel, unless, measured through the chord, in which case it’s 38 deg.[/QUOTE]
It sounds as if you are not setting the level at 0° with the "alternate 0" when the flaps are up. It doesn't matter where you measure as long as you measure the same place after setting the "alt 0".
