Sustaining Knife edge?

[Del Rykert]

Hi Ihncheol..
     A couple of thoughts come to my mind. Not knowing what plane but is canopy on perfectly straight?. Does vertical fin have a slight twist,? Speaking vertical twist here..  are you using pushrods and does it flex back a little when being pushed instead of pulled and that is direction of weak rudder.?  Is your output on servo wheel balanced with its deflection.? in otherwords are you getting more torque in one deflection versus the other.?  These are just some of the issues I would be looking at and this doesn't include all but will give you some starting info.  Hope this helps...

  I have a question to ask.
  Flying condition was very good.  Almost no wind on ground level, maybe a few
  MPH in the air (flying height).  Wind direction left to right.
  When I fly knife edge from right to left facing the top of the plane, very
  little rudder is required to stay on without going up or down.

  However, from left to right facing the top, the plane just can not stay and
  keep dropping.

  What could be the cause of this?
  Side thrust?


  Thank you,
