Another update:

I now have the nosewheel steering installed..
Good god what a mess they made of it! And its obvious, kind of annoyed I didnt notice the problem myself!

I decided to try the pull-pull system, so I got on and installed it and noticed 2 big problems.
First it was fouling with the throttle pushrod and connector, so I had to "invert" that so that the connector is under the servo arm rather than ontop as normal..
the 2nd was that the cable tighteners are the PERFECT length to jam against the body of the throttle servo when the gear is retracted and the plane inverted..... (see first pic in this post)

SO.. in the end i've removed that, and used sold pushrods left over from the retract system I didnt use and installed that...it wasnt exactly easy either.. once retracted I was unable to get full left rudder but right wasnt a problem... not sure why, technically it should be ok but somewhere it is messing up.....
I´ll just look at it again with a clear head after a break doing something else.
