RaSTuS Should've mentioned it involves a little case modification. Also found the solder pads not adhered as well as could be. My solution was to drill a series of 0.9mm holes through them with a pin vise and solder on a 3pin dupont header, drill the first hole through the middle of the centre pad, then use the header to align the outer holes, they should fall near the inner edges of those pads.

RaSTuS Have to swap out the piston rod ends from the original shocks for it to work with the upgraded wishbones/a-arms.

RaSTuS Doesn't work properly on the 959-B model since the drive shaft cog is bigger now and it interferes, will have to take a dremel to it.
