ah, what mizuinu is probably thinking is that he has a S&S sound and the receiver has a # on it. HL uses 1-4 for the smoke and sound. the non smoke and sound use 27, 40 and 49 mhz and each has 3 selections on the tanks and receivers. I would either order some from the previously mentioned place or order some from mato. http://www.matotoys.com/canada/

umm i cant find them on mato's site. they might be sold out. you could email him i guess.
