I replaced the Haggy motor mounts and belt drive warp nacelles on the Enterprise with the AVIO MKII gear drive by @avX. This kit rocks! The drive system itself is extremely quiet as expected.
I went on a quick test ride and managed to hit 33 MPH uphill and still had plenty of torque remaining. I rode back home because my taillight battery died and left the board on to look at Metr data. While looking at stats, Bluetooth disconnected and I noticed that the anti-spark switch LED was off. Then I noticed the smell of electronics burning…
I grabbed goggles, gloves, and quickly removed the enclosure and disconnected the Flipsky FSESC 6.6 ejected the warp core.
The battery appears to be ok, but this ESC is FUBAR.
