Shadowwolf1 this will work with any of the dumborc transmitters.

Shadowwolf1 the manual is very basic and not very well done. only shows the servo and battery location. you'll have to wing it on the esc,receiver location. But there's a lot of room at the front.

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.
