Final update tonight.
I decided to have a fiddle with the steering section, first part that impressed me was the sealed RX box to protect it, im going to pad it out to ensure any vibrations dont affect it, secondly the neat wire soloution where servo and PT wires run under the box and up into the RX box, hopefully the pictures explain this better, its neet indeed!
Secondly the servo horn itself, i wanted to keep my answer rc horn on rather than a plastic one, so I placed the 2mm spacers behind servo so it doesnt catch with the mount itself, then I used a countersunk washer to scre through so I can mount the steering arm. the soloution works well, there is 1mm clearance behind the screw to the servo, I just need a longer screw so it grabs the M3 nut on the otherside.
