Hi Guys,
Well, I made it past first flight!! (Ref. http://sonexbuilders.net/viewtopic.php?f=23&t=5722#p43247)
Now, if the wind ever dies down a little I hope to get some more time on the plane. Since it seems senseless to fly it again without making improvements I intend to try to improve the out of rig conditions before flying again.
Of course any observations made during the first few minutes of flight are suspect. There's just too much adrenaline and too much going on. However, I do know that the left wing was heavy. Just how heavy I don't know. So, I'll apply a very slight squeeze to the right aileron before further flight. That should make the plane easier to fly and land while determining just how much more is needed.
I suspect I need some rudder trim but won't be sure until I fly level and get my feet off the peddles. I'm not too worried about the rudder trim. Based on what others have posted it's easy enough to fix with various trim tab designs using VHB tape. An easy fix and easy to change. I could mess with the rudder return springs but I don't fit under the fuel tank very well.
So here are the questions: How much interaction is there between rudder and aileron trim? Does it make sense to fix the roll and then fix the yaw or should it be an iterative process, sneaking up on straight and level?
Thanks,
Wes
