Flycolor Raptor Mini 20A BLHeli Multi-Rotor ESC 2-4S (OPTO)
These Flycolor electronic speed controllers have been developed specifically for multi-rotor use. They use a high performance MCU processor that gives a smooth, linear and precise response, The Raptor is silabs F330 Powered with dedicated fast switching gate drive, which is perfect performance for multirotors.
The Raptor ESC keeps the weight down and comes in a small package but is still top quality. With low resistance IC’s producing little heat and giving more efficiency.
The ESC comes flashed with 14.2 BLHei Firmware utilizing Oneshot125 communication protocol making it fast and responsive to throttle movements. Easy upgrading and downgrading firmware is a simple process through the BLHeli Suite.

The only escs that have not blown on me, the performance is top dollarGreat slim ESCs.
You can read and flash them through blhelisuite 188.8.131.52 through cleanflight and naze32 board. They have Silabs bootloader and they read as Emax20A BLHeli 14.2.
Ok an update on my review. Attempted to flash these with the afro usb tool suggested here. No go, tried everything I could. Com port is correct, correct driver from silabs, esc beeps motor when connected but refuses to be read. Same error over and over telling me to connect and power or power cycle. Bl Heli programmer only has Atmel listed under Afro and I'm pretty sure these are Silabs. Either way no luck. Perhaps I'm doing something wrong and someone els can figure it out.Just installed these on the S500 frame with Naza Lite upgraded to MV2, Sunnysky 2212 980kv's, 1045 CF's. Excellent, super small and lite and all 4 weigh less than one Blue Series they replaced. Not even warm after 15 mins. Only minor issue is the slight twitch on arming but I have yet to even check the firmware settings with the BlHeli flashing tool. All in all great ESC's, will be using these for all my projects unless something much better comes along.
