Thanks Kevin.

Sounds like you have a handle on the problem.. Yes it does look like a flet
tner strip.
-
If you can't find material close by contact me off line with your address,
I'll send some to you.

Jim,

I flew today with a friend (mutiple RV owner/builder) in the right seat. He
's a far more experienced and talented pilot than I. The plane turned RIGHT
ever so slightly hands off. The ball was off about the same to the left.
-
Stalls dirty with the two of us broke a little to the right at low power. H
e did lots of stalls and thought the plane flew very nicely. So I'm not goi
ng to do anything regarding roll correction.-I have a TruTrak autopilot i
nstalled but not hooked up yet. I imagine it will work well for longer flig
hts, without aileron trim, solo or dual.
-
-I like your rudder trim solution. If I understand correctly it looks lik
e-a flettner strip on our trim tabs?
-
My RV friend landed the Europa-mono four times, each one getting better. Ma
de me feel better to see that he did some light bounces and showed me that
a fine touch on the throttle does wonders. He was impressed with the 914/ai
rmaster combo!
-
Thanks, Kevin

I had the same problem that you have, the ball was out about a quarter to t
he left. I solved my problem by installing a wedge of balsa wood on the RIG
HT side of the rudder.
-
The balsa wood came from a hobby shop, and is used for trailing edges on mo
del wings.-It is shaped like a wedge. The front is maby 1/32 and the rear
is 1/4 thick.. cut it to about 2 inches long. Temporary install on the Rig
ht side of the rudder with the 1/4 inch thick part at the trailing edge of
the rudder. Also locate it about half way down from the top of the rudder.
I used masking tape to hold it on. Then go fly, get plane in normal cruise,
take feet off pedals. where is ball. If the ball did no quite get centered
.. Use a longer wedge. If ball went to far, cut the wedge shorter. and go fl
y again. After a couple tries you should have the ball centered in normal c
ruise.
-
You can attach any way you want. Glue it on, use vinyl tape, RTV....
This makes a neater installation than gluing a piece of aluminum on the rud
der and then bending a tab to accomplish the same result.
-
When you start flying cross countrys at 17.500 ft you will see some very im
pressive ground speeds. It blows the controller's mind when you tell him yo
u are flying behind a Rotax. They think two strokes.

Hi Jim,
I have- to hold just a little left rudder in cruise to center the ball on
my Dynon. Seems like I am skidding just a bit.
When I use the stick to level the plane I can do it with one finger, just a
pound or so to keep the left wing up cruising solo. In this position of wi
ngs level the ball is off to the left just enough to put the ball 1/4 on th
e line.
When gear and flaps are down, the left turn is more pronounced. And when st
alled dirty the left wing always drops.
-

Thanks to all for the responses. I have not tried changing anything yet. I
have just been enjoying this great little plane and trying very hard to get
better at landing her. I have been doing a lot of landings! And also some
high cruising, 17,000 feet over the snow covered Sierra, just amazing to be
there instead of in the garage...

Your statment "in cruise I have to hold a little left rudder".. Is this to
keep the plane from a slight turning to the right? Is the right wing low wi
thout rudder ?
-
The next time you fly, do this for me. Once in normal cruse, take your feet
off the rudder pedals. Use your stick to level the plane, then observe whe
re the sticks position is. Is it to the left of center or is it to the righ
of center, or does it remain centered ? In this position of wings level, w
here is the ball? Is it to the right, or to the left, or is it centered?
-
The monowheel-does have-a tendenancy to turn left a little, when flown
solo.

I would think that given the left flap is lower than the right flap that th
e plane would be turning right. Given that the left flap will have more pre
ssure on it than the right flap.
-
I would suggest that on the next flight check the turn and bank ball. and s
ee if its setting to the right. Try centering the ball with rudder and see
if that helps.

Hi All,--- ---
-
Flight testing of 914 powered monowheel N211KA is going well (29 hours).I h
ave a flap position question for those who have been there.
The aircraft has an irritating-left turn in it when flown solo and slight
left turn with two up. When trimmed out cruising straight and level the ai
lerons are close to even with the wing tips and the left flap is noticeably
lower relative to it's aileron than the right side, which is almost even w
ith the aileron. I think if I can rig the left flap up even with the ailero
n it will help cure the left turning problem and be less drag.
-
I thought I might get a new flap hinge arm (FL16) on the left-and with th
e aircraft supported and flaps up in the desired position I could drill new
holes thru the lugs on the tourqe tube- so the left flap retacted positi
on matches the right.
-
Will this work or is there a better way?
-
Thanks, Kevin... flying and grinning...
