I think I need a new board for my Dromida Ominus after crashing in water. It ran OK after that for awhile but now won't link up. Looking online for a new board there seems to be 2 types out there, a Dromida E-board Green and a Dromida E-board - Red. To me they look the same but the Red is about 1/3 less expensive. Anybody know the difference? Also, any thoughts on why I cannot link up or is it the board?
