HMS Erebus - Posted: 20th Jan 2015
Royal Navy Erebus class monitor, launched 1916. Decided on this ship as rather a strange looking ship. Scratch build, hull carved from basswood. Hope to have her 15" guns firing. Currently cutting out the hull templates.

Question is then what did change!? Have you made any mods to the boat or had any kind of accident with it before this phenomenon appeared ?

One forward / one reverse will only work if you either use one stick for each motor (2 RX ports) or use a mixer coupled to the rudder. Some captains also use micro switches on the rudder servo to reverse one engine at full rudder. For high currents change-over relays are needed. Wiring gets complicated! 🤔
Happy experimenting. Cheers Doug 😎

Hi again
for simple current & power check have a look at these review videos for Watt meters.

i just bought one (€12.00) and it works a treat.
Whatever the label says they all seem to be made by Busing!
Cheers Doug 😎

I do believe you have answered the problem when you mentioned the size of the props and motors. They may well be capable of supplying the power but that comes at the cost of higher amps. If your original 50 amp blue controller eventually gave up then a 15 amp Mtronic will struggle with just one motor and be totally overwhelmed with two motors.
As Doug has just posted you do need to get a wattmeter otherwise I suspect you will be cooking ESC's on a regular basis.
Experimentation is fine but it can become a tad expensive if you do not have the right tools to help you make informed choices.
