Since I has some leaking in the eletronics compartment I havent been able to try the board for a couple of weeks. I have also replaced the VESC 6 with the ARC200.
And now, after some epoxi work and a lot of sanding it was time for another test run yesterday.
The good news is the electronics compartment is now water tight. No leaks
In the end it was the Maytech remote that failed me It has never been a problem with it but now it is stone dead. Battery failure obviously. The remote battery cell only gives 0.3V after its been charged.
Discouraged by the stories here about the lousy Maytech customer support I will look into the alternatives.
Any suggestions how to get into the water again fast and cheap?
