half speed on FOC vs BLDC

Hey there!

I have been running BLDC for a while now and getting up to 43kmh but I just switched to FOC and I cannot get a speed above 18kmh.

My setup is the Flipsky 6.6+, dual motor control. The duty cycle is hitting 95-100% and I have tried programming for medium and small motors, and also programming with and without the timing belt installed. So far, still getting this 18kmh speed limit. I saved the settings and according to the mobile app the max speed is 87kmh so I don't know why I'm being speed limited.

Would truly appreciate any ideas out there!!

thank you!

What was your mistake? You should post what it was regardless.

@bgdwiepp - I forgot that the KV was cut in half on the new set of motors I am testing
