I've just finished having a few runs around the garden with mine now
The last car I built was a Bosscat back in 1995 so I haven't got much to compare the build to.
They're pretty good buggys for the money. There's a few things that aren't brilliant, mainly the front wheel fitment. You can't do them up tight otherwise they won't spin freely, so they wobble a bit. Also I've had trouble getting the slipper clutch to slip! Even at the slackest setting the diff slips before the slipper. I had to file a couple of mm or so off the outer slipper hub (where the spring presses against) to slacken the tension off it to get it to slip easier.
A couple of the hub mouldings don't hold the bearings too tightly either, they're not really loose, but some of the bearings will fall out where as others are a nice fit.
Other than these things it's great. It drives nicely out of the box (although I've fitted 4wd minispikes all round and fitted ballraces) with plenty of steering.
I'd say they're a great car for beginners and club racers alike.
Who decided to fit the front body clip that way around though?!!!
