After several weeks of gnashing of teeth and threatening to shove it down the garbage disposal, I believe I have reached trim I am happy with ! Thanks to Dave and Bob for the pointers in the past!

Huurrah! Once you get to play in open water, it will all be worth it. Keep us informed.

You do two changes at a time you won't know which of the two was sour and the other good -- you learn NOTHING! Occam's Razor suggests addressing the most obvious fault first. I recommend you pick on the transmitter first. If it ain't the transmitter, only then **** around with the receiver.

Might be either of those- could be a power supply issue. What BEC are you using?
I once had an intermittent fault on a sub, that was a so and so to isolate, it would randomly affect the ballast control, turned out toe a duff signal wire on the ESC that controlled the ballast pump, and the fault was inside the esc's board, so it was I spy with my little x-ray eye.Last edited by Subculture; 02-11-2020, 05:24 PM.Comment

BEC???????? UHHHHHHHHHHHH dunno. Using an Mtronics speed control............Well, when it stops working, the only thing I have operating is the auto depth thingamajig (ADF 2). I recharged the TX battery and ran it down to almost zero. I then turned on the sub and it was OK for a few minutes, then it went dead. The TX battery then read 60%. So I dunno. I'm gonna try another transmitter. Never had this before............Comment

That said, the other servos and devices will up the current draw off the receiver bus, and that may tax the BEC to the point if skittish operation. Bottom line, get a dedicated BEC in there rated for at least 3 Amperes.
Get a fresh battery in that transmitter, bang it up and test. Transmitter circuitry is usually rock solid -- it's almost always the battery that lets you down.
You might consider taking the red wire out of the lead between ESC and receiver and plugging in a receiver battery. If things work fine after that then you have a bum MTroniks BEC.

Your receiver has many unused input ports (it's an 8-channel unit, right?). The BEC input wires go to the battery, and the BEC's output plugs into one of the unused ports which puts the BEC's five-volt supply to the entire receiver bus. Remove the red lead from the ESC's receiver lead so you isolate that devices weak-ass BEC -- you don't want it screwing with the dedicated BEC's operation.Last edited by He Who Shall Not Be Named; 02-12-2020, 10:24 PM.Who is John Galt?Comment
