HI i'm building a ultimate kaos 60 as a spare sport airframe.the plans show 1 inch dihedral under each tip.my question is if i cut it back to say 1/2 inch under each panel(1 inch total)would this have a good effect.i'd like to use it for practicing entry level pattern(fixed gear) any advice out there?thanks............</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=3 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

The UK needs that much dihedral to fly knife edge correctly. I think you will find that the model will tend to tuck down and roll in the opposite direction of applied rudder, in adverse roll and pitch couple. It will make the plane harder to fly in a neutrally balanced, Pattern like way. You can always mix in the correct elevator and aileron electronically, but why go through the trouble? I<BR>

In fact if you choose to make your change and do not mix in the correct mixes, landing would become more difficult everytime you correct the plane in yaw.<BR>
