I got tired of not having an easy way to just attach things and test them. I remembered a long time ago @lowGuido did this to one or more of the boards in his giant pile of esk8s so i did the same.
The only thing that’s semi permanent here is the drive train, though swapping belts and pulleys and wheels is as easy as always.
The important thing here is i can test any pack with any ESC and any receiver, and even try different eswitches or bluetooth units or whatever else i want just by plugging it in and sticking it on and strapping velcro over it. So now FlipSky and the like will get all of my opinions a little faster.
The picture above doesn’t have the blanket of velcro covering everything so you can see what’s up, but after i strapped it all down i picked the board up several times to shoulder height and just dropped it. Nothing came loose. However, this is by no means weather proof so dry days only.
At the moment I have a pair of 10Ah Tattu 25C 6S lipos in series with a Y connector going straight into a FlipSky FSESC4.20 dual ESC that they sent me, running 3.40. Used VESC-Tool to set it up, no issues at all. Running sensored FOC.
No eswitch, no volt meter, not even an antispark plug.
Its fucking raining right now. I’m so pissed. I know this monster will move like a motherfucker. If anything can dump enough current to melt this flipsky its these Tattus, and i want the pcb on fire before i start sending opinions.
is this dual ESC even out yet? I don’t see it on thier site. The single is.
Also they have an eswitch coming. I’ve been trying to talk them into making one with a lot of fets and a midi fuse holder, the bolt in style. They just keep telling me about their 8 fet switch that looks like it could turn on the starter for my truck.
I use heavy duty Velcro on lots of my projects, its an underrated tool and seriously tough. It held my enclosure to my mountain board with ease and as a bonus isolates vibration.
It should be dry enough when i get home to run this board down the road. Setup was really easy using VESC tool with this ESC. I was expecting it to complain about firmware or some stupid shit, but it just worked. We were trying to do burnouts on the dusty garage floor yesterday while it was raining.
its running the latest firmware, 3.40, which is excellent.
Works with VESC-Tool right out of the box with no issues.
can be flashed back to 2.18 easily to work with BLDC-Tool if you prefer the older stuff
integrated can bus connection is really nice and saves time
works well in both FOC and BLDC mode when it does work
supports multiple control schemes and has all the needed ports to take advantage of them
small, almost perfect form factor. I really, really like the size.
THE BAD:
there is a hardware issue that leads to complete power loss during hard acceleration and hard braking. There is little that can be done in the settings to mitigate this.
on the other hand… we have the Unity which is what i’m testing now. Its kind of fucking amazing. Everything is… well… dreamy and perfect. I don’t know how else to describe it.
For example, i ran motor detection on a shorted fucked up motor:
The Unity is perfectly fine, in fact i ran it around the block a half dozen times, hitting the accelerator hard and braking hard too. Then for more fun, i unplugged one phase lead and rode it some more. Sounded like shit and went all quirky but nothing bad happened.
Next we’re going to light it on fire and beat it with hammers.
