Have had a rather expensive afternoon.
I did a simple job in moving the water cooling outlet pipe from the side to the transom for the RTTL. Put a Y section in the pipe work to have twin outlets so disconnected the rudder linkage to gain access. Reconnected after fitting pipe work.
Thought I’d just make sure everything worked so grabbed a 5000 Mah 3S, connected the battery and the Rx stopped working. Checked it was paired, took Rx (Flysky i6) out of boat, put another battery on it, dead Rx.
So, tried another Rx.
Connected battery and the 60amp ESC decides to produce smoke, now have a dead ESC and the replacement Rx also burned out, sniffed both Rx and they both had a burned smell.
Did what I should have done when killing the first Rx and looked for any issues, found the rudder linkage was way too tight after I’d reconnected it and was causing the the rudder servo to chatter.
Checked the battery, found I’d picked up one with a low charge of 42%.
So, I freed off the rudder linkage and tested again, this time outside with a spare Shark ESC and another Rx, borrowed from my BYMS. All works.
Would a jammed rudder have caused an Rx to burn out? Would this have caused the issue with the ESC burning out? I use Deans connectors so no chance of reversing polarity into ESC.
Any opinions welcome!
