TJ’s offer is for a single OG foc Box, not a unity.
I have two OG focboxes that arza sent me.
One of them has that distinct burnt electronics smell, the other has it too, but to a much lesser degree.
Since they will not fit to my enclosure’s heatsink, without major modifications to it, I have not tested them, or pursued employing them, at this point.
I have tons of questions on hooking them together, but will not ask, yet.
I just opened the focboxes up, and cannot see any obvious fried component on either side of the PCB which might be making that unsettling stank.
Future enclosures that I build are going to have larger heatsinks, that will accept any dual drive esc, or two singles, but that could be a ways off.
The heatsink in my enclosure was located and designed and built for the ‘puaida’/Lingyi ESC on the right and to possibly squeeze 10s 3p of 21700’s inside at a later date.
I know now, that that size battery would never fit though. 10s3p of 21700s is a pipe dream in this enclosure and honestly, I have enough range with 10s2p of 2600mah 15 amp 18650’s on smooth flat Florida asphalt.
Being able to secure the Fsesc 6.6 mini and ebay lingyi cockroach between the vertical studs on this heatsink, was just luck.
I’d love to get the FSesc 6,6 mini powering my hub motors, but when I last tried, and failed, I had a back up board to ride that kept me sane, mostly, I think.
Hard to tell.
That backup board is now down and was too slow to properly scratch the incurable itch.
I don’t want to disassemble a functioning board, without a back up.
Not for a maybe.
A new 110$ 2024 ‘puaida’ ESC would require me to xt90 and MR60 it, easily attach it to heatsink, then plug and play and good enough, far better than Ebay lingyi nuclear cockroach anyway.
I could likely spend 70$ and get another pre2024 Puaida esc with weak ass brakes, and pair my remote to it, but That possibility assumes that my previous Puaida ESC is faulty, not the remote.
Ideally, I’d make a real board that does not need to fit inside my kayak’s hatch.
One with pneumatics which opens up the areas I could ride locally, but are too uncomfortable, or too dangerous for 90mm urethane.
That board is even further away from realization than my imagined backup.
If my Lingyi cockroach fails, The Fsesc 6.6mini will immediately be returned to enclosure, and hopefully my hub motors will not sound like microwave popcorn popping, after running detection.
But if I fail again, then I need a back up ESC ready to employ, so I can tow this sweet, fluffy 11 year old goofball, at least 50 miles a week.
