Thanx again for the informational post Nathan.. and Nathan.
I'll just keep doing what I'm doing then, double up BEC's from multiple esc's -> as long as they are running on the same volatges & putting out the same BEC voltages, too much current likely will never will be an issue.
Just got home from xmas in the city the last 5days.. went to a large general tool/automotive store this morning (Princess Auto), got lost in there for about 3hrs
and I found this nifty little bilge pump
.. suppose to be capable of putting out 170 -200 gph meant for boats & what not, runs on 12v.
Outlet is 7mm id -> taper it down to 3 or 4mm should produce pretty good press for either a nozzle or spray bar the width of trk. Put it on an esc to vary the voltage, which will vary the press & flow. It can be totally submerge, so I'll just put it right in the tank! Start building my water hauler here shortly for the floor dig.
