Hello, this will be a very slow build due to time constraints, but I have made enough progress to start sharing and to ask advice…
So, this is a large jetboard for cruising out the back on the larger waves which aren’t breaking. It’s a big, buoyant aircraft carrier. I weigh 100kg and the total buoancy is 175kg. The board should weigh around 30kg. The important bits are;
2 x MHZ 58 jet units
2 x Scorpion HK-5035/760KV
2 x MakerX 300A VESCs
2 x 10S 12P battery packs
I am running dual systems as everything just gets too big (cables, VESCs, etc) with a single drive. As well, I like the reliability of two completely independent (almost) systems.
I will be running water cooling for the Scorpions and potentially for the battery packs.
Here is an overview of the design to date;
I will go into more detail on the design later.
I have just completed a test build of the electronics so that I can develop the sofwtare to run two systems from a single remote.
I have successfully run the VESC motor configuration tool on both motors and VESCs. The issue I have is that when I throttle up slowly, they run smoothly. If I throttle quickly, they vibrate badly as they ramp up. See video here;
Notice one of the VESCs goes into a fault mode.
Has anyone else faced this issue? I would imagine I now have to do some fine tuning in the motor configuration to smooth out the ramp up.
Any suggestions appreciated.
