    Came from Naze and was not disappointed. Very solid controller, quad flies very steady.

    I have owned several naze 32 boards before I got the x-racer. I will never go back. This is the best flight controller I have come across. I flashed it with betaflight and run sbus, it is extremely responsive. This board is acro only, so beware..but if you will try it, you will love it.

    The best flight controller for the money hands down! Don’t waste money on a naze32 when you can get f3 performance for the same price plus the other features with the X racer. Buy a couple of these boards because you’ll love it so much you’ll want to put in your next build. I run this on my 180 racer with the latest beta flight and stock Pids and it RIPS! Buy the X Racer what are you waiting for?

    So far, my first choice for an F3 FC. I just loaded on 3.0.1 of BetaFlight. I haven’t had a chance to fly it yet, but this thing was rock solid on 2.9.0!! Only assuming it will get better from the comments people tell me!! It’s such a quick and easy install. My quad was back together and fully bench tested in an very short time. Great quality, great features, and a great price. Repeatability is key to success!

    Fantastic board and perfect pinout locations. Some things I love:
    – Fast sourcing from SRD.
    – Dedicated SBus pins for easy receiver connection.
    – Easy telemetry connection
    – plenty of onboard blackbox memory
    – vbat and buzzer pins well located
    – Price!

    You can spend $20 more for a board with a poorer layout if you want. I’m on my third X-racer.

    I love this FC, works great, and amazing features. The value is unbeatable even more so when you don’t have to wait for it coming from China. Thanks guys!

    LOVE THIS BOARD! I should have gotten this board a long time ago. I was having trouble tuning my SpaceOne 220 with a Naze32 rev6. I switched to this board and now it’s locked in! I’ll be using this board for all my future builds!

    This is an awesome fc, I’m not much of a racer but love this for acro. Super stable, even on cleanflight. Strictly racing drones seems like a solid company which is hard to find, I got my order in two days… Better than Amazon prime, free shipping

    The f303 xracer has been my favorite flight controller since it came out. The fact that strictlyracing drones now carries them here in america is awesome. V3 added the 8kHz gyro up from 2kHz and it was already fast enough at 2kHz. This thing is awesome and has all the features it needs and they keep improving upon it everything they needed in v1 is now on v3.

    This is a great fc, I love the flash button, it’s a luxury item in the world of flight controllers but it makes the flashing my fc that much quicker. This board is striped down to the essentials needed for racing and acro. I was all about using the dodo fc but with 3 of these in my quads now. I’m very happy with the x racer awesome value.

    Strictly racing drones mailed mine out quickly I will be getting my next batch of fc’s from them. 🙂

    My favorite F3 board on the market for these reasons:

    -ALL PINOUTS! Seriously, the use of pads on flight controllers is only asking for trouble, having all pinouts results in a more robust board that can be desoldered and resoldered many times, and easily.
    -16mb onboard memory for blackbox. Makes BB logs easy.
    -VBAT, LED Strip control
    -Logical board layout
    -ALL PINOUTS!! Seriously…eff picoblade connections!

    I have been using the XRacer since February when it was V1, I use V3s in all three of my quads now.

    The fact that SRD makes this board available in the US for the same price as FPVmodel in China is awesome. Thumbs up guys!

    Great value for the $$$. Actually a great flight controller regardless of price. V3.1 looks even better with an SPI enabled gyro.

  14. 5 out of 5

    Great flight controller with the perfect amount of features for the money. Easy to set up and I love the low loop times.
