I forget the number but its Futabas latest one that cranks out 340 oz, my rudder blade is of good size and length, it turns easily, even ifI choose to rail the buoys. Im pretty sure a touch of tow in on the inside sponson will fix it, Ive periodically needed to do this to the many Eagles Ive owned and raced. I was mostly curious if people were finding if there was any difference in the prop walk of a set of 1667s vs the new style props. I always set my Eagles up to give me fairly responsive left turn correction capabilities but found with this Twin it fought me more than I like. Ive watched Allen Yuen over the last couple of years battle the same issue and he loses a lot of speed while he does so. I try to tune my ride to a more compliant ride so that I dont scrub off speed while Im fixing a driving error or avoiding a race course hazard.
Ill get there, just takes more testing and tuning.
I found no noticeable difference in prop walk between a 1667 style prop to a 19 degree rake ABC prop
