Please tell me what do you think about that setup, I’m starting to build my own mountainboard, has to have speed and range, below I created a part list, is mainly Chinese, but I guess is worth using, at least some of this parts
Board - Ground Industries Patrol
Engines - sensorless, 190kv
VESC - Flpksky
Anti-spark with switch - pro version
batteries - 3 pieces
To convey power from motors to wheels I’m planning to use chains and metal sprockets
I’m still not sure about BMS tho, what do you think will be fine?
I’ll create my own motor supports, from the block of aluminum
I was wondering and troubleshooting a lot, and as much as I’ve already got mountainboard set, I don’t know if the setup I’ve chosen is right
I appreciate any help, sorry for missing parts if there are any
I would get lower kv motors and a 10s or 12s battery thats ATLEAST 10ah. A 5ah 9s battery will give you about 4-6 miles of range at most.
Those vescs might be the older version of the fsec 4.12 before they upgraded them.
You should try for 150kv or less with 12s while using a vesc 6. I recommend the flipsky dual 6.6. It runs 12s foc flawlessly
Also, you probably want sensors.
if you are looking at doing a chain drive system you could have a look at sprockets and chains on
https://www.gearsandsprockets.co.uk/ i’ve found these guys to be a one stop shop for this type of stuff.
probably want a 04b chain and sprocket to go with it, would have to ask around about chain on mountain boards as i have no experience with building them.

Ok, lets say I’ll get FSESC up to date, what’s the difference between one and two devices, besides the number?
And 150kv will be good for small hills? I need speed but it would be usless when i’ll not be able to go up the small, long hill
Sensors will make it go smoother?

Primarly I wanted to use sprckets and chains from minibikes
You need to balance kv and voltage to get you good speed and torque balance.
The difference is that the vesc 6 uses better hardware and is more reliable at higher voltage. It also has higher current abilites which you really need for a mtb
Don’t forget that the 4.2 flipsky’s and the 6.6 flipsky’s have a voltage drift of -0.6/+0.6v…
