I ran my spartan boat last night and it ran great. I recharged the batterys and went to run it today and now i have a problem. I only get intermintent responce from my transmitter. When i pull the trigger i only get it to sputter. I checked the batterys and they are fully charged. i made sure that the low-voltage dect.is on . Not sure what else to look at. Any ideas. I also changed the batteries in the transmitter.
