904 behind 360

I'm not woried about making it harder, I want to make it cheaper. The b&m costs $85 but these speciality balanced converters don't seem to cost anything extra. So if I keep the stock converter the b&m is less but if I want more stall seems like just buy something with the weights added rather then buying both. Once this is together there is no going back and changing things. I'm just a poor boy with a family to raise still!
