Thank you, i do have all the correct extension wires, i was may be 1cm short, i pulled the lot of it apart, i found (
Plate Special 2 x 2 with 1 Pin Hole [split Underside Ribs]
http://www.rebrickable.com/parts/2444 ) attached to the front servo motor was rotated the wrong way, and the drive 50cm extension from the back two motors needed to be freed up a little.
While doing the build i also found that the wires if bent the wrong way would clip the gear teeth from the outrigger extension drive train.
i would love to see build guides that have temporary jigs for the placement of wiring at with correct routing and distance, even the Lego group, i find it the hard sometimes.
I have (
LEGO Set 8879-1 - IR Speed Remote Control ) and had hoped to use it for steering an drive but the two function are on different
receivers
Anyway thank for your help. and the community for one of my most rewarding builds
