My friend built floats for my old Kadet MK II. It floats really well, takes off and lands like a dream (Picture 1). Even I can make landing look easy!!

But it doesn't taxi worth a darn. Not enough rudder control. In the wind it's hopeless. So I'm fabricating a "water rudder" or tiller for one of the styrofoam floats. I need to control the tiller from the rudder servo in the cabin of the fuselage.

My problem is that the golden rod red/yellow push rod system I'm trying to use doesn't want to bend on a small enough radius to get the job done (picture 2). The red outer guide crimps if I try to bend it short enough and if I avoid that the yellow inner push rod drags so badly that I don't think the servo can overcome the friction.

Any ideas for me on a more flexible push rod system that might work in this case? Or any other ideas at all??

Thanks
