Flycolor Raptor5 ESC Buying Guide

The Flycolor Raptor5 is available in 20A, 35A, 45A, and 50A versions, with all versions supporting 3–6S LiPo batteries. The main difference is their current capacity, so choose the ESC based on your motor's maximum current draw, propeller, battery voltage, and flying style.

All four versions support 3–6S LiPo batteries and use Flycolor_Raptor_5 firmware. None includes a built-in BEC.

1. Choose the ESC by Motor Current

The most important factor when selecting an ESC is the maximum current drawn by your motor and propeller combination. As a general guide:

20A — for setups with relatively low motor current and a strong focus on low weight

35A — a good all-around option when 20A does not provide enough headroom

45A — suitable for higher-current motors and more aggressive flying

50A — choose when your setup demands the highest current capacity in the Raptor5 range

Do not choose an ESC based only on motor KV. The same motor can draw very different amounts of current depending on the battery voltage, propeller size, pitch, and throttle load. Always check the motor manufacturer's current test data with your intended propeller and battery.

2. Which Raptor5 Version Should You Choose?

Choose the 20A if: 

-Your motor has relatively low peak current 

-Weight is a priority

-You are building a lightweight FPV aircraft

-Your motor/propeller combination stays comfortably below the ESC's current rating

The 20A version weighs only 6.5g and measures 29 × 14 × 6mm, making it the smallest option in the Raptor5 range.

Choose the 35A if:

-You want more current headroom without increasing weight

-Your motor can exceed the practical range of a 20A ESC

-You are building a general-purpose FPV setup

-You want a compact ESC for a moderate-power configuration

The 35A version has the same 6.5g weight and 29 × 14 × 6mm dimensions as the 20A version, while providing substantially more current capacity.

Choose the 45A if:

-Your motors have higher peak current requirements

-You fly freestyle or racing aggressively

-You use higher-power 5S or 6S setups

-You want additional current headroom for demanding throttle inputs

The 45A version provides 45A continuous and 55A 10-second burst current.

Choose the 50A if:

-Your setup has particularly high current demand

-You regularly fly at high throttle

-You want maximum current capacity from the Raptor5 series

-You prefer additional overhead for demanding builds

The 50A version supports 50A continuous and 60A 10-second burst current.

3. Does Raptor5 Support 6S?

Yes. All Raptor5 versions support 3–6S LiPo batteries. However, choosing a 6S battery does not automatically mean you need the 50A version. Your ESC requirement depends on the complete power system: Battery voltage + Motor KV + Propeller + Motor current

For example, a 6S setup using an efficient motor and moderate propeller may work well with a 35A ESC, while a high-power 6S setup with an aggressive propeller may require a 45A or 50A ESC.
