Hi Carl,

What do the flaps look like? Are they raised to equal positions?

My mono needed a little left rudder in cruise, so I added a fixed aluminum trim tab to the rudder.

[quote]Hi Everyone,



I'm fairly new to my Europa, only logged a handful of hours, and there is one flying characteristic that's bothering me a bit.



* Just pilot in LH seat

* Aileron trim is set to full right

 * Feet not touching the pedals

* ASI speed about 116 knots

* Balance ball on the left, just over a 'whole ball's distance



So...



* I step on the ball, applying some left rudder.

* Then i change the aileron trim, as full right no longer appropriate

 * ASI Speed now slowly climbs about 3 knots to 119.



This tells me, with the higher airspeed, that my balance ball is accurate and to get the aircraft in balance I need left rudder.  What's bugging me is how much left rudder, it's a fairly substantial pressure, enough to make my left foot feel irritated after 10/15 minutes.

 

The question is - why does the aircraft need some left rudder to keep balance?  Is there anything i can adjust/correct to make it naturally balanced so i can take my feet of the pedals?



Thanks in advance,

Regards,

 -Carl.

Hi Carl,



As Kevin suggested, check flap rigging.  Then check aileron rigging.  If you feel up to it, check the engine offset to make sure it's within specs (Europa XS Rotax 912S or 914 Engine Installation Manual, Chapter 1, Engine Installation).  If everything is where it's supposed to be, then it looks like a tab is needed on the rudder.  

Perhaps Bud can chime in with some additional suggestions.

The flaps certainly look level and balanced… but it depends how much accuracy you need 

The trim tab sounds like a good idea – what's the best way to affix this?

Hi Carl,

     

     I had a similar thing on mine although I added  a balsa Flettner     strip (like the ones either side of the stab trim/anti-servo tab)     but on one side of my rudder (rather than a tab sticking out) and     that did the trick. I painted it to match the rest of the rudder     after determining the size needed. I have a similar one on the     underside of the right side aileron. I do notice that when I carry a     passenger I have to hold in a little left aileron as I didn't have     any kind of aileron trim.

     

     You can just see the rudder trim strip at the 40 second point of the     YouTube video.
