need ESC & motor
hi..im building a boat and trying to figure out which parts i should use...looking for suggestions...
i plan on using a 6volt SLA 10 or 12Ah battery....and im thinking the motor should be a speed 600 brushed.
it doesn't have to be super fast, but not a turtle slow either....decent speed id guess. 10 to 20mph would be nice.
here's the thing, my budget is less then $20 for the motor and less then $30 for ESC, would also like to have reverse.
the boat will be using a single propeller & rudder system...very basic.
here is a photo of the hull i should be using. it's about 29" long & 11" wide

It will be hard to even get 10mph with all that weight. A typical speed 600 motor with 8 cells (9.6v) running in a FE hull would run about 20-25mph.
Using more power will only cut down on your run time. In this case I believe slower is better than less run time.

Well...considering this pop bottle (which looks pretty quick actually) is going 7mph, I doubt you'll see 10mph.
Is the battery the same as the Dumas 2 1/2lb battery on the Tower website? If so, that's quite a lot of weight to have for only 6 volts.

wow that looks so much faster then 7mph.....if my boat went that fast id be more then happy.
the 6 volt SLA battery is something like [link=http://www.ragebattery.com/batterystore/SLA-10-6.html]this one[/link]. it weighs like 4 lbs lol i need a lot of battery life.

RE: need ESC & motor
it might be awhile before i begin the build....but will keep you guys posted.
know any good online stores that carry 3 blade propellers? i think im going to get one in the 30 to 40mm range.

RE: need ESC & motor
i was thinking the motor over again, and i was wondering....because that particular model graupner is hard to find in the states...for some reason im not sure. i wonder if i could find another motor/brand that is equivalent in specs & size. low RPM, low current drain, etc.

If you look at the 8.4v motor they list 9100 RPM loaded. This is rated running 9.6v. Running only 6v will be about 5500RPM. I believe this is about where you would like to be.
Current in amps is not critical at all. The motor will draw as many amps as it wants depending on what prop you toss at it. A smaller prop decreases current draw a larger prop increases draw.
