This build has been many months in the making while accumulating parts. Hence the name “Blackhole Evo” as this has been an expensive journey. But alas, it was worth it. The final product is simply awesome.
I started with the basics that I knew would be in the final board.
-Landyachtz Evo Falcon
-107mm Abec 11
-Caliber II trucks
-Riptide bushings
Planning out the power system I knew that I wanted to use a newer vesc than the TB 4.12 that I already have. The breif moment I had with FOC was great, so that was going to be a criteria for this build and I needed something reliable. I had already purchased two Focboxes earlier this year from their summer sale, but didn’t know if I wanted to use those or not. A short time after that another Escape GB started so I jumped on that and a GB buy for two Flipsky 6.6 as well. So in the end I had 3 three different ESCs to choose from. That was expensive, but curiosity has a way of spending my money.
While waiting for more parts I had some time to mill a heat block for the two Focboxes. The part turned out better than I expected and I was actually curious to know if it would make a noticeable performance difference. Plus I went with a 10s5p battery so it made more sense to use them anyway.
So for the electronics:
-Dual Focboxes
-TB 6355 190kv
-10s5p 30q battery
-Nano-x remote
-HM-10 bluetooth module
The 10s5p came from @psychotiller , a double stacked flat pack that fits the board well. Unfortunately neither of the two enclosures I got from Psychotiller would fit the deck without loads of modification (why can’t I just copy what others have done). So I went with the @eboosted enclosure, not knowing if I’d be able to fit the battery.
I’m glad I did, with a 3/8 in foam gasket the eboosted enclosure fits perfectly and looks great. On a side note, this is the only way I will assemble boards from now on. Attaching everything to the board was so much easier to get the clearance I needed. Removing the enclosure is also much easier.
On the drive/powertain, I wasn’t going to bother with forward mounted motors. I’d rather not have those space restrictions even though I really like the stealth look with FOC. So instead I’m using TB extended reverse mounts along with 18t motor pulleys and 36t wheel pulleys. Red wheel pulleys came from ebay and needed to be lathed down to 12mm.
Upon testing I immediately determined there was either an issue with the motor, sensor wire, or Focbox because hall detection was not working. After eliminating some variables I determined that one of my new Foxboxes was faulty, the one that came with the mangled connectors…
I really didn’t want to deal with Enertion, but I had spent too much effort configuring this board for focboxes. I decided before getting too angry to open the ESC and see if anything obvious stood out… and there it was.
very fortunate to just be a bridged connection
With the problem fixed and FOC working perfectly it was time for a test ride.
I used these settings:
Motor max 70 motor regen -40 Batt max 40 batt min -10 (not sure what I can go up to here safely)
Despite how I feel about Enertion I really like their remote. The speed selector switch should be standard on all remotes. On full power the board is a rocket and feels just as good as my other 12s board with 6374s. Top speed is perfect too, right at 40mph thanks to the 18t wheel pulley. Feels very stable and I have no problem taking corners at speed. Couldn’t be happier with the performance.
Couldn’t get the HM-10 module to pair. I really wanted to see some actual data but the module will not pair to my android phone. It’s visible as “HMsoft” in bluetooth settings, but when I attempt to connect it doesn’t. Not sure if I have properly enabled PPM + UART on the ESC. I select PPM + UART but when I check the vesc tool again (App Settings> general) it shows only PPM.
If you have any insight I’d appreciate a comment.
Thanks for looking.
