Problem: I'm having the usual problem of communication blackout when putting more power into motors. I am flying using a keyboard on throttle setting *one*, yet the communication is still very fragile and drops occasionally. I tried a stress test by attaching ROV by a piece of wire and driving forward - after 4s voltage goes down on the cockpit and I can't steer the ROV (even at slightly less than 11V). If I'm lucky this lasts only a few seconds before I regain the control and the video is still transmitted. If I'm less lucky, then I need to reset the rov (USB) or even open-close the battery tubes. The soft freezes tend to be less related to the motor load, the hard ones are. Very reproducible, even on fully charged batteries.
ROV version: 2.6
Batteries: TrustFire 26650
Is there anything I can do to limit power provided to the motors? I was thinking about reprogramming the ESCs with something other than "Rock Crawler". Does it make sense?
Problem above aside - I just did open water testing last week and it turned out quite positively. Other major problem I had was fogging, but I guess I haven't yet put enough desiccants inside.
