New to electric skateboards - Can't seem to get FSESC set up properly

Hi Everyone,

I recently purchased everything I needed to build my own electric longboard and it turned out to be much more of an undertaking than I expected.

I purchased two Flipsky 6354 190KV motors, a Flipsky 4.2 dual FSESC, a Flipsky VX1 remote, and a 10S4P 10.8 Ah Lithium Ion Battery.

The pulley I have on the wheels is 36 teeth and the pulley I have on the motors is 15 teeth.

My issue has been with correctly setting up the FSESC, I've watched several tutorial videos and I've read through other forum posts but I just can't seem to get it right.

I plug in one of the VESCs and run the motor config and the motor type was set to FOC with the sensor port mode of Hall Sensors. I had everything set up and I had the motors spinning in the correct direction but when I took it out for a test ride I was only able to hit a max speed of 15mph and when I was going full throttle the VESC would cut out and I would start to coast.

I'm pretty lost here and I really want to get my board up and running and any help or advice on how to set up the FSESC would be awesome.
