Hi Bobcat,
Thank you for getting back to me, i've brought some micro servos from ebay and got hold of a tamiya gearbox from.

They have been very helpfull still a little confused about wiring motors up to work as i would like them too and voltages but i'm hoping that i can learn that as i'm going along. Looking forward to build it may even post pics to get peoples opinion.
Cheers
