Depending on how your speed controllers are wired internally, you might end up letting the magic smoke out!

The negative supply of M1s speed controller is 12V higher than the negative supply of M2s speed controller. If the black wire that goes from your speed controllers to your receiver is also connected (internally) to the negative supply to the speed controller then both negative supplies will be connected together, via the receiver.

If the black wire isnt connected to the negative input then you dont have a problem, but if it is, somthing will have to give, probably a pcb track in one of your speed coontrollers. I thought you might want warning :-)

Ill check my electronizes later when I get home to see if they have signal ground connected to their negative supply but I think the IFI victors have them connected and some other ESCs do.(http://forums.delphiforums.com/n/mb/message.asp?webtag=THERFL&msg=3706.8&search=yhttp://forums.delphiforums.com/n/mb/...3706.8&search= y)
