Jkoiva (or others),
Do you have the current limiter set on your RX8? I just built up an 811be 2.0 and installed an RX8 and T8 2050Kv. I have my limiter set at 90% but was curious as to if I could run with it off. I've only just finished and run it up and down the street a few times. I haven't even discharged the packs yet.
I would, especially with that size motor. You'll be doing a lot of wheel spinning which won't help much with lap times, but will help with grin times
. I'd drop it down to 75 or so to start off with and go up or down as needed.
