<DIV>I understood that you are flying Sportsman. Therefore, don't worry about snaps and spins. You will learn to set the plane for those maneuvers later. </DIV>

I always try to give the servo's the best mechanical <BR>> advantage possible and still get the throw I need. <BR>> <BR>> I have read the trimming guide published by Peter Goldsmith in the <BR>> AMA mag last year and try to follow that when setting up my planes. <BR>> <BR>> I was at almost the full servo throw - 45 degree's on the ailerons. If <BR>> I go to the outside hole of the round wheel that should give me aprox. <BR>> 35 degree rotation in each direction. that will give me some room <BR>> for a higher rate condition for snap, spins if I need it. <BR>>
