    haha darn i emailed stephen he should know what to do, because if i find a batery store for the propper better it will be like 2 1/2 hours away so that means when the battery will no longer hold a charge ill need to go back to the same place hoping they will have another one to replace it, were as walmart will almost always have them in stock and walmarts are everywhere

    If you get a a few SLA's, even if its via mail, they will last you years. I don't suspect you would have a problem running a 360 on 12v, however it may not run optimally if it was setup for a different voltage.

    Are these motors 12v or are they 6-12v or are they 6v or 7.2 volt.

    Some small motors don't like to run at full voltage for any length of time under a heavy load. They will heat up very quickly and burn out. If your using Esc'S you can control the voltage going into the motors. 6v will probalby be not be strong enough to move the model adequatly and efficiently.

    ok i ran into a semi huge problem. i burned up all 3 360 motors in my Bismarck, im running a 12 volt battery into a 6-12v esc ( viper marine 40 ) then to a fuse then to all three motors, it looked as though the esc was getting hot too but not sure but i know that the motors are fried. any suggestion, and i really don't wanna get rid of battery because i cant return it haha, but any ideas on this would be greatly appreciated. I have a everstart premium power sport battery (ES4LBS) http://www.walmart.com/ip/Sealed-Lead-Battery/17385901?findingMethod=rr and i read on this site its really bad to use this type of battery is this true?All i want is my ship to run strong and fast for a long time thats it haha.
    Curt: im sorry i read over your post god i think i shoulda answered you first haha i beleive that they are 7.2 well were 7.2 its whatever 360 size motors are. well they couldnt handle it, and what you were talking about with the esc im not sure what you mean buy control the voltage going through i saw a calabrate for top speeds and top reverse speed but other than that i didnt see anyhting in ym viper marine 40 manual.

    hey Dave,
    Get the 6-12v Motor (550) Drive motors, from Battlers connection, they are $5.50 each!!! I have two of them for Doria!

    The other thing you could do to reduce voltage to the motors is put both motors in series. That divides the voltage between them.

    O===||
    || ESC / Switch
    O ===||
    Wire from ESC / battery to one motor. Wire from One motor to other motor. Wire from "other motor" to ESC / Switch

    Doing this halves the voltage going to each motor, but the current draw is equal across the circuit.

    The other way, putting the motors in parallel, means the current is halved but Voltage is full to each motor.

    Now what happens when you stall one of the motors wired in series? Not a recommended practice for model ships unless you are using the motors geared to one shaft so they stall at the same time.

    DO NOT WIRE DRIVE MOTORS IN SERIES, EVEN IF ONE DOES NOT STALL, THEY WILL TAKE DIFFERENT AMOUNTS OF VOLTAGE SO ONE WILL STARVE AND THE OTHER WILL GET TOO MUCH!
