Looking for a hassle-free way to get your FPV race copter up and going?  The Graupner Quad FPV Racing Power Pack will provide everything you need to start configuring your 330 - 500 sized multirotor models.


The included Graupner Brushless motors ULTRA 2812 920kV are high-performance motors designed to work hard under challenging racing conditions.

The motors are specially machined with high tolerances and hand-wound at the Graupner factory, making them ideal for 330 – 500 sized copters. The design provides optimal efficiency and good cooling during operation. The special multi-turn winding and the 12mm magnets ensure high torque with direct drive for optimal performance and excellent power-to-weight ratio.


The Graupner Ultra Control 20A Race ESC is the perfect controller for any multirotor, combining a compact design (23 x 12 x 5mm) and light weight (7g) to provide fast response times.  The ESC settings have been specifically optimized for use with multirotor models.

The Ultra Control 20 A is based on the latest BL-Heli Open Source Software and the flight controller is presently the only open source Electronic Speed Control that uses the advanced 50MHz Silabs processors. With twice the clock rate compared to its predecessors it guarantees higher maximum speeds and precise timing at high speeds.

The amplifier is housed in a 3.3 x 3.3 DFN package. The field effect transistors (FET) have an extremely low internal resistance (<1.7 mOhm). Special FET drivers provide a more effective active recovery and better cooling for the amplifiers. The ceramic capacitors allow super-fast start-up times and guarantee high operational reliability.

The active Damped Light mode allows a more precise flight behavior. The Ultra Control 20A Race automatically detects normal (PPM) receiver pulses and ONESHOT-capable flight controllers like the Graupner GR-18.

The Ultra Control 20A Race can programmed and updated with the Graupner USB updater (P/N 7168.6) using the BL Heli desktop software.


This Power Pack comes with the GR-18.  When combined with a Graupner HoTT radio it takes mere minutes to setup your configurations and get up in the air.

The GR-18 flight controller is the cornerstone of many of our copter products like the Alpha 250Q, Alpha 300Q, Hornet and Alpha 110. This unique flight controller also contains a 2.4 GHz receiver equipped with our HoTT protocol, providing real-time telemetry and convenient wireless setup of telemetry and flight controller settings. The GR-18 supports almost any type of multirotor configuration from Tri-Copters and Quads on up to Octo Copters.


The included SBEC (Switching Battery Eliminating Circuit) will power your systems, such as receiver and cameras, with a continuous current of up to 3A. When used with a Graupner radio the SBEC provides real-time telemetry voltage information about your main battery pack (up to 22.2V) and can be programmed to provide multi-level telemetry voltage warnings to notify you about battery power levels, significantly reducing accidents.

The SBEC provides voltage between 4.5V and 8.0V, sufficient to power multiple servos and FPV systems.  Adjust the voltage level needed for your system by using a HoTT radio or Smart-Box.


The included Graupner C-Prop copter propellers have been specially designed for multirotor usage. Quieter than standard propellers they produce less noise, making them suitable for aerial photography.  The thin blade profile provides higher efficiency and ensures longer flight times.


Note:  A Graupner radio transmitter (sold separately) is required to use the Power Pack and GR-18 flight controller. Look for our special radio offers during the checkout process.
