Yep, I am going to try butter flying the rudders "out" on my Bob Cat. You can set them up to go in or out and I choose OUT. It takes three channels to implement this setup, one for each Rudder and one for the nose gear steering. I'm hoping they add a little drag and help stabilize the wiggle. I will know shortly as maiden flight should happen this week! Using the 10X I still have an extra channel Aux. 2. I'm using the match box on the elevators. and separate channels for ailerons. Flaperon for the differential capability, and maybe a little flap! All of the extra functions are easily switch able on and off for testing. Also has anyone tried flying the Bob Cat without the main gear doors, they are easy to remove! Drag aside, is the wiggle completely from the doors or are the low profile fins the real cause of the wiggle?? I did vent my gear doors per Tony's solution also. I should know the answers to all of these questions within the next two or three weeks.
