Help In RC fishing boat
Right lets see
1 Standard servo for rudder and a more powerful one to chuck the bait out
2 ESC with BEC no battery needed, ESC without BEC separate battery for receiver needed
3 A motor from an old battery drill, say 18v or 12v run on 12v battery, no water cooling required (I use this set up on a springer tug, plenty of power)
4 ESC needed. Fasten motor down on a bench, connect up to a 12v battery with an ammeter in series on the side, try to stall the motor with a piece of wood, NOT your fingers and take the highest reading on the ammeter, then choose an ESC that is above this reading
Hope this helps a little.
