I'm at my wits end and would love any troubleshooting suggestions anyone may have. My college professor bought v2.4 quite a while back and it was just sitting around in the box. I volunteered to put it together and get it going. I put everything together meticulously and everything works like a champ on dry land (i.e. countertop). I loaded the "2.4 stable release" and the arduino code loaded fine from the cockpit as well. All lights, motors, controls work and test out just fine.
The problem is when I put it in the water and try to run around. The tube is watertight with no leaking as well as dry battery tubes. As soon as I throttle the motors up in the water, within a few seconds the cape and beagleboard completely shut down. I have to pull the batteries and reboot only to do the exact same thing next time I drop it in the water. I've done several test and regardless of whether I throttle the vertical, port or starboard motor it does the same thing in the water. Again, everything works fine out of the water.
Anyone have any ideas for me? I'm stressing :)
Has anyone seen the motors being throttled in the water shorting the whole board out somehow?
Thanks in advance! Buddy
