Eachine Racer 250

What you get in the package The box,  contains everything you need to get up and flying except a radio and a receiver. 

My understanding is that Banggood plans to offer a full RTF package as well, but for now that doesn’t exist so you’ll need to supply your own radio and receiver for this version. 

Also included and installed is a video transmitter complete with an OSD (On Screen Display) and a circular polarized cloverleaf antenna.  The OSD is nothing fancy, but it does provide the information you most need for this type of quad – the selected video channel, the current battery voltage, and your flight time. 

Other items found in the box are a battery and a pretty decent charger, two complete sets of props, a cable to allow you to turn the headlights on and off from your Radio, a neck strap for your radio, and an adapter for the charger for european outlets.

Configuration Before you dive into the configuration you should bind your receiver to your radio and connect the receiver up to the Racer flight controller (a 32 bit CC3D based controller). 

This is because part of the Vehicle Setup Wizard involves having the software learn your control channels, so you may as well just get your radio bound and configured first so  you won’t have to stop and do it in the middle of the wizard.  A step by step walkthrough of the vehicle wizard is beyond the scope of this review, but there are plenty of resources available online to assist with the GCS setup.

Part of the setup process is choosing a model which the wizard will use to set up some initial PID settings.  This provides a good starting point, but you will probably want to fine tune your PIDs a bit to get it flying smoother.
