Apparently hobbyking was going to stock axles which will attach to these but they haven't appeared yet - you could use a collet with a long screw as an axle for the wheel or do as I have done bend the last bit of the axle and extend it with some brass tube then use a pin through a hole in the end of the tube and washer to hold the wheel on - it would be easier if they made the leg longer but they aren't forthcoming with that option.
