Eachine have now entered the FPV racer sector with their new “Eachine Racer 250” this dual camera CC3D model follows on the same theme as their previous by offering a competitive price. The BNF version arrived today and this post shares my first impression and also benefits SEO as it seems no one else is talking about it yet.

Racer 250’s body breakdown

The full breakdown of what is in the BNF kit from the user manual and the product page.

It is prebuilt and ready to race out of the box(you just need a receiver and trabsmitter, something that can be a good or bad thing depending on your preference. Some people like to build one and the sense of accomplishment is also greater if you have built it yourself, if you are a beginner it also gives you the foundation of exactly what all the pieces are and how they all connect together.  The benefit of this prebuilt model is you don’t have the risk that you break something or don’t construct it properly, also if you have built before it might not be challenging to build another. The frame is fresh and has the serial number ZFEAE5BD4 and a date 2015.07.11.

The Video FPV System

Included is a mushroom antenna and it screws in the top, the polarity is unknown at this stage and will be checked in the teardown. The system also incorporates a switchable OSD so you can keep an eye on the stats of your battery, runtime and a few other readings, we are planning to connect it to the screen in the next few days and see exactly how it all shows up on screen.

The 3 layers of the frame, the transmitter is on the top and the flight controller sandwiched between the bottom 2. The lights are bright headlights and more than adequate in both the day and night. The top rear view showing the long red tail light. ESC’s are wired inside rotor arm and sit flush to the bottom.

The Eachine Racer’s lights.

Racer 250 follows the current trend and put some eyes in the front and a star wars style red banner LED light on the back. Orientation is very easy to spot and the LED’s in the front generate enough brightness to be a good headlight for flying in the dark. The light’s themselves seem to be long and similar if not identical to side mounted LED’s for your boat or trailer.

The front and rear light can be turned on and off by the slider switch on the left side of the 250 frame.

The battery

The 3 cell battery included is a 1500mag 11,1V unbranded High discharge Lithium Polymer battery, likely a generic factory made one, or perhaps they are yet to stamp Eachine on it.

The unbranded Eachine battery.

Included is also a decent looking balance charger so your battery will be safely charged, useful if you don’t have a good charger yet, if you do it could just be something that drives up the price a little bit.

The camera

Included is a front mounted camera with a sliding upward angle adjustment allowing you to fine tune your perspective to match your flying angle.

Camera 2 is not included and is designed for recording via action cams such as your XiaoYi or GoPro cam. There is not room for a gimbal, just rubber stabilization, but you don’t need it, it’s a racer after all.

What’s included

  • The prebuilt quad – All you need to do is charge the battery, screw in the diatone props and screw in the antenna.
  • A balance charger and cable – it has a figure 8 plug so can be plugged in from an international connector.
  • 4 white spare blades.
  • A carbon fiber style spanner to install the props.
  • A soft foam cut package with a cardboard box on the outside.

The external box on the right and the soft inside foam. The blades and antennae have been installed already. The B3AC charger offers 2 Cell 1.5A, 3 1A, based on this we can expect about a 1.5 hour recharge time for the standard 1,500mah 3 cell battery.

Where is the RTF with controller?

Eachine will be giving us some of them soon, they will have 3 versions available to cater for different users so don’t worry if you don’t have a controller or screen. We don’t have a confirmed prices yet for the other 2 versions but I did spot this in the user manual.

Their are 3 versions, the naked quad, the controller version and the controller and FPV receiver screen.

The 250 Racer Teardown

We have not flown it yet but we have already stripped it down and revealed all it’s secrets, well, at least what we can visually see.

The frame is simple and easy to dismantle, all you need is a hex screw and .5mm socket for the flight controller bolts. Putting it back together is only tricky at one point, between the top frame and the motor arms you need to put 2 spacers on the corner of the rotor arm, not difficult just a fiddly part. I put about 5-10 mins to deconstruct and reconstruct (excluding any fiddling to get those spacers in).

Do you have something you want to know about the Eachine 250 Racer?

Let me know we have it here and would love to investigate, it gets me off the computer so hit me with something to check out!
