I read on "RCTimer/Turnigy/Hobbywing ESC DIY Firmware Flashing" rcgroups. Some people have similar problem with latest bs_nfet on F-20A. It seems ESC is the most possible problem.
I appreciate if someone using F-20/30A ESC and MT3506 motors can share the info which bs-nfet firmware is the best used with AQ?
Thanks,
John
