Model Forum / Radio Controlled / Water Models / May 2009battery hookup
I am planning to build a boat with parts. I plan to put in two 7.2V motors, and I wanted to know if I should put in two motors in the boat (hooked up to double power) or if I only need one? Thanks!  Signaturemaster robot Free RC Model Boat Plans: http:\/\/www.modelpowerboat.com\/forum\/downloads.htm You could get away with one motor. Check to see how much voltage your motor can take as you might be able to hook two 7.2 batteries in series and feed 14.4volts which will make it go faster. But if your motor can't handle the volts you may burn it out. SignatureJohn Free RC Model Boat Plans: http:\/\/www.modelpowerboat.com\/forum\/downloads.htm Would it work to hook up the motors and battery(s) in any fashion that would allow me to use two motors (the motors' max V is 8.4). Also do I need to buy speed controllers and do they come separately from the radio? Signaturemaster robot Free RC Model Boat Plans: http:\/\/www.modelpowerboat.com\/forum\/downloads.htm A speed controller is the best bet. But you can rig up a servo that activates a switch that puts power from your battery to your motor. The downside is, you only have two speeds - flat out and stopped. With a speed controller you can go slow or fast and some even have reverse. SignatureJohn Free RC Model Boat Plans: http:\/\/www.modelpowerboat.com\/forum\/downloads.htm So if i hook a speed controller to each motor, I could use two batteries toput out 14.4V (if the spped controllers can take that V)? Thanks for this help. Signaturemaster robot Free RC Model Boat Plans: http:\/\/www.modelpowerboat.com\/forum\/downloads.htm |
