Robert: May I suggest taking the plane to the field and putting it through the following flight test to see if you need the rudder to airleron mix in other flight manuevers/lines. A good pilot will not put a mix "in" or assign it to a swtch until he/she has flight tested for it. There is no way to "look" at the plane, or take instruction from this forum and get it correct. Your answers are waiting for you in the air. Please do the follow to obtain your answers.

1. Fly staight and level and then give rudder only, see if the wing dips in the same direction that you are giving rudder. Most planes do this. This is the same direction the wing is moving in KE flight that you describe. If so, the rudder to ail. mix described above is needed on that line too.

2. Do a hammer head stall turn (you'll need to do several). If you are hammering with left rudder, see if the left wing dips to the gear, most airplanes do this, they do this because the wings are NOT stalled in a hammerhead. The outer panel (the one that is arcing in the largest circle) has more air over it than the inner panel (smallest arcing one), and that wing lifts while the plane is "in" the hammer. Usually causing the hammer to torgue off, and cause a correction of the downline to exit on the same line as entry. The KE mix decribed in the above posted will help this to stay on plane (geometric plane), or counter this, help this not to happen, etc. So now that mix is needed on that line also....

3. Put the plane into a vertical upline with some speed, get a good running start at the upline. Right after you establish vertical apply a little rudder (as in to do the top half of a KE loop), see if the plane rolls with the yaw command. If so, you need the rudder to airl. mix on that line too.....

Most competition guys who run that mix have it on all the time. They have found that it is needed on most lines whenever the rudder is applied. Firsts find out if you too need it all the time. If so, just make sure all switches are inactive on the switch selection screen, and it will be on all the time.

Hope this helps,
