Shadowwolf1 it's per wheel

Shadowwolf1 yes you can use normal arc welding rods

Shadowwolf1 the wheels are aluminium, so will add weight

Shadowwolf1 this is purely for a 1:16-1:18 scale car

Shadowwolf1 comes complete. its literally a bolt in unit

Shadowwolf1 should be a switch on the transmitter, to restrict the throttle

Shadowwolf1 they should arrive at same time,but its not garenteed

Shadowwolf1 you can't change the 2.4ghz to a different one. but you shouldn't have a problem with interference, as the reciever will only respond to this transmitter. it you need to bind other recievers to it, you can use dumborc ones.
