I don’t have experience with this remote, but I remember the older version had connection issues. You can use a calculator to get your erpm max. Even with 12s and 190kV you shouldn’t hit the erpm limit under load. Did the cut out happen at top speed?
The calculator says my max erpm is 49000.
I’m not 100% but I’m pretty sure it cut at a relatively high speed.
With the remote issue would it just disconnect from the board and then just coast or would it apply full brakes to the board?
