Alpha 250Q from Graupner

Details

The Alpha 250 is a pure FPV Race Quadrocopter, developed for flying with goggles from first person view. Equipped with FPV camera the flying experience is like a simulator or a real plane. FPV racing with quadrocopters becomes always more and more popular.
You can createracetrack layoutwith gates, flags, or even pipes that must be flown through, or it is set a track with trees and corridors.
The frame of the ALPHA 250 is completely CF, which is extremely rigid and insensitive. The 2 bottom plates, which gives a streamlined look, allows the installation of 4 Brushless ESC, and stowing over long cable.
An ideal addition to this is the use of the gyro-receiver GR-18 or GR-24 PRO, which already contains a full Flight Control for attitude stabilization.Thus can be dispensed with an additional board together with additional cables. The 4 brushless controllers cables are simply plugged into the receiver and gyro will do the rest. From the telemetry menu of the HoTT transmitterit is possible to complete the setup of the gyro receiver. It is also possible to customize to your own needs the sensitivity of the flight control very easily via the telemetry receiver menus of the GR-18.
The Voltage Module allows the timely warning of a empty battery, so that the model can be landed in time and safely.
Due to the easy handling, the model is also suitable for less experienced pilots.
