Hi all, I,am new to the forum & require some help please on a project – I,am revamping a Baitboat for fishing – I have upgraded the motor & ESC (G2 HYDRA 50 kit from Mtronics) and replaced the lead acid 6V battery with a Lifepo4 12ah 12Volt – I've installed new Futaba servos etc.
The problem i,am having is that the boat goes at slow speed, but when i turn up the speed it slows down? the prop shaft is 5mm where it joins the motor shaft which is also 5mm – these are connected with a stainless steel universal join – at the propeller end the shaft is M3 on which a 50mm plastic 3 blade propeller is mounted – the propeller seems very flimsy, and I was wondering if this is collapsing under the strain of the new motor ?
If anybody can advise me that would be great.
I,am also getting a lot of heat from the ESC, after a while 10mins – the motor judders like its getting intermittent power.
Below is a link to a youtube video that shows the same boat as I have. Single propeller & rudder steering.
