You will see a lot of trainers using nyrod for fuselage pushrods where there may be a few five to ten degree bends but try using it for a hundred degree bend or worse two opposing ninety degrees bends in opposing directions and it is like slamming on the brakes. When that happens it becomes difficult for the rudder to rudder adjustment to remain uniform.

For Rudder to rudder this is the product to use:

If you got it working then great go ahead with it but you may want to consider doing it the easy way next time. If you go to a float fly sometime you will see the all external flex cable arraingement is the 'standard'.

By the way you could not have made a better choice than the LT-40 for a first floater.

Here is just one more thought. most trainers will suffer flopovers while on the water in some wind conditions with new folks and when they do go inverted they will float on the wingtips with the nose submerged and the aft cabin area well above water level. So with this in mind if you position the Rx completely down in the floor of the cabin area to the rear under the fuse pushrods then the Rx will stay dry in most flop over situations.
