RE: RDLogics SHo
Apparantly there is both a rtr and a pro version of the SHO. The engine that comes in the rtr is a Team Infinity which isn't that great. And in Denmark at least, it doesn't come with a starterbox.
The SHO is basically the same buggy as the Protech Enigma XS and this buggy goes amazingly well especially considering its low price. But go for the non-rtr version and put a better engine on it.
You should also make sure that you can get parts for it. From over here it seems a little difficult to find them.
