Frequently Asked Questions:

Q1. What does the "OPTO" designation mean for this READYTOSKY ESC?

Ans. "OPTO" on an ESC means it does not have a built-in Battery Eliminator Circuit (BEC). This means the ESC directly passes the full battery voltage to the motor side and completely isolates the signal path. You will need a separate UBEC or a flight controller with a built-in BEC to power your receiver, flight controller, and other low-voltage electronics.

Q2. Is this READYTOSKY 2-6S OPTO ESC compatible with modern flight controller protocols like DShot or OneShot?

Ans. The READYTOSKY 2-6S OPTO ESC typically supports high throttle refresh rates (up to 621Hz, beyond standard PWM). While it offers fast response, its compatibility with advanced digital protocols like DShot, OneShot, or MultiShot can vary depending on the specific firmware version. For guaranteed digital protocol support, it's advisable to look for ESCs explicitly stating BLHeli_S or BLHeli_32 firmware.

Q3. What kind of motors is this ESC optimized for?

Ans. This READYTOSKY ESC's firmware is often stated to be specifically optimized for "disc motors," which refers to brushless outrunner motors commonly used in multirotors. It has very good compatibility with a wide range of such motors within its current and voltage limits, ensuring smooth and efficient operation.
