Don't do it like Andy did.. He forgot to make a crossbrace in his design, resulting in a wasted wheeliebar.. Those rc18T shocks are too soft imo. Your better of using a revo shock. (though you don't need a shock in a wheeliebar..) Make one on your rear skid, like Andy did later. Ryan Coombes also has got a simmular wheeliebar. (he was the first who had this type of wheeliebar) it was produced shortly in the UK,

Use dubro airplane wheels, with an aluminum inside (looks cool) and is stronger than those RS4 wheels..
