125 traxxas have 3channel use the 3rd for the nitrous dee dee dee and does any one use 8sec. of nitrous lol
125cc for get about the price price always is super high on new things and yes imo it is way over priced and who says you cant run this with a full ported and polished motor just for kicks
and if this nitrous expresssystem cost 25.00 you and me would buy it in a heart beat
