[PSUBS-MAILIST] PLC Choice

[Alan via Personal_Submersibles]

Steve,
thanks thats good to hear. 
I bought my Vesc from Maytech in China. They sell them along with a remote
controller for skateboard use. They look like they have done a good job, &
if they haven't you'll hear about it from the Skateboarding community.
My Vesc cost about $100- & they are about to release a Vesc with heat sink
in an aluminium housing.
The Vesc Maytech sent me needed the firmware updating, & then I had to order
an ST link from them to update the firmware. They sent the wrong wires with it.
Apart from that, I have been buying bldc motors from them that are good quality.
Will let you know when they release this & what the price is if you like.
I was looking at the focbox, it looks like they have done a good job with it.
Cheers Alan

They also can have a Bluetooth module added so everything can be monitored on a smartphone app (Android).
