The Flycolor X-Cross 35A is the upgrade of their popular Raptor 30A ESC’s. The X-Cross ESC runs the latest BLHeli_32 firmware and support Dshot1200 protocol. It’s compact and lightweight at an affordable price.

Close Look at the Flycolor X-Cross ESC

The Raptor ESC’s (BLHeli_S) have been a reliable option, a lot of people are still using them. The X-Cross is the BLHeli_32 upgrade. They are actually in a similar form factor so replacement should be easy.

These ESC’s come with 10cm 18AWG silicone wires soldered on, the signal cable is 18cm long. Soldering pads are big and easy to work with.

There is a built-in colour RGB LED which is great for night flying. You can change the colour in BLHeliSuite.

There is ESC telemetry pad as well as signal ground pad on the ESC.

Note that there is no built-in current sensor on these ESC’s. If you want to get current usage info, you’d have to use the current sensor in your FC/PDB.

The BLHeli_32 firmware these are using are FLYCOLOR_X_CROSS_BL_32_MULTI.


I will test these ESC’s on a quad over the next few weeks, and report back if there is any issue.

35A Not Enough?

Flycolor also make 50A version in case you need more power :) Banggood (, Amazon (

I want to get the Flycolor X-cross 50 amp running in “normal” mode, as far as motor direction is concerned.

I can get it to work in “Bidirectional” but if I try “normal,” I cannot get the motor to work. It just makes a lot of beeps. These beeps are likely some sort of error code.

I tried with two different motors, just in case one of the motors was defective.
Any thoughts?

ESC: Flycolor X-cross 50Amp
Firmware – BlHeli-32 (updated on both computer and ESC)
Motor – Turnigy Aerodrive SK3 – 5045

Please join so we can help you troubleshoot. And please start thread stating your setup, what FC and ESC protocol you using.

I can’t get the ESC telemetry working on the Matek System F722-SE F7
I connected the ECS’s TX pads to the FC’s RX6 pads, however, I didn’t wire the minus cable – can this be the reason?

Oscar 1st December 2019 - 3:59 pm

It should work without the ground wire, but Why not give that a try just in case?
