Need advice with steering

Post by Dan Coffey »

First time doing crows foot steering. Steering works smooth until you put power to them and the the rudders want to center up. And you cannot fight the stick. I think I've done something wrong with the angles causing a leverage problem. Please look at the pictures.

It's a little difficult to tell from the pictures but it looks to me like the pivot points where your rudders mount are too far forward. The vertical rod that goes through the rudder, (pivot point), should be about 5 or 6 inches back from the front of the rudder.

I read your post earlier and was hoping someone with more experience with building rudders would chime in. I've noticed it's more difficult to get an answer on weekends probably because most folks are out riding.

If I'm not seeing the rudder correctly I'm sure others will share their knowledge when they get time. Hope this helps!

:scratch: why so many bars on the rudders?? I only have one between the rudders at the front bottom and one going from the stick to them..... seems to me that's your problem :dontknow: your going to feel everything in them with no slack

The pivot point on the rudders is 5 inches from the leading edge. There is one bar between the rudders. We added the longest bar (the one going to the trailing edge of the rudder) on the crows foot trying to fix the problem. It did not work.

The rudders appear to be very close to the prop for one. Secondly the ratio between the rudder stick length from the axis to the end vs the distance of the crows foot from end to rudder axis is very high which will over power your stick reaction, I shoot for 2:1 this appears to be close to almost 4:1, you have the option to move stick axis down or build a real long crows foot.
I never finish anyth,,,.

My thought was the rudder stick leverage is my guess. :cheers:
