Hi Dave. You wouldn't recognise the X-5 now mate. Its coverted to lipo. Its a proper beast. I think it'll be my weapon of choice come the regionals outside. I bought the X-5 cos I was struggling to find the sweet spot with the Cat and wanted an alternative in case I couldn't crack it. Now I've got the Cat just about sorted so its really easy to drive and very quick(despite the driver). The Cat is defo easier to live with cos it comes apart if you whistle whereas the X-5 is a little more involved. Had some minor drive train issues early on with the X-5 but think its sorted now and it too is very quick and reliable. It is by no means a "dud". I love it. Only prob this end is deciding which one to use. Cat so far cos I was determined to get the hang of setting it up and driving it. The X-5 seems well sorted with its set up. Easy to go very quick with little fuss. Just to confuse matters a little more I am eagerly awaiting the arrivel of my X-6 squared. Can you ever have too many buggies? I think not.
