Ready to turn your FPV Racing Drone into a 100+ mph speed demon? By changing just a small number of parts, you can take your FPV flight experience to the next level. Read ahead to learn about the fastest FPV Drone Racing parts.
1. Brushless Motors
The top-speed of your FPV Racing Drone is largely determined by the total thrust generated by its motors. A stock Eachine Wizard produces 3120g thrust from its 4x motors giving a top speed of 68mph, whilst the Diatone GT200 2017 produces twice the thrust (6644g) pushing top speed to 99mph. The simplest way to increase thrust is to upgrade to more efficient motors that squeeze more thrust out of each amp from the battery (e.g. BrotherHobby T2 & RacerStar BR2205). However, bigger increases in thrust require heavier, higher power motors (e.g. T Motor F80 & Cobra Champion) that in turn require heavier, higher power batteries and upgraded ESCs. This increased weight will boost top-speed but reduce manoeuvrability – to increase thrust whilst preserving manoeuvrability on the the race-track, you should upgrade to motors with higher power-to-weight ratios (e.g. BrotherHobby R5). Compare different brushless motors using the table below.
2. Electronic Speed Controllers
High-thrust, high power motors require ESCs that can handle the extra current required. You should select an ESC with a burst-AMP rating that matches the burst-AMP rating for your motor. Burst-AMP ratings for ESCs are usually underrated – an ESC with a burst-AMP rating of 40A will typically handle a motor with a burst-AMP rating up to 45A. Compare different ESCs using the table below.

3. Lithium Polymer Batteries
The high-thrust, high power motors required for top-speeds greater than 100mph need powerful batteries. The ‘S’ rating of a battery (e.g. 3S, 4S, 5S or 6S) indicates the number of cells in the battery, with more cells providing a higher voltage. Higher voltage increases the motors RPM and thrust directly, therefore you can use batteries with a higher ‘S’ rating to boost the speed of your FPV Racing Drone (as long as your motors, ESCs and other electronics support higher voltage). However, the weight of the battery increases with the number of cells, reducing manoeuvrability of your FPV Racing Drone. To increase speed without reducing manoeuvrability, you should choose the lightest battery with a given ‘S’ rating. Compare different 4S batteries using the table below, check out the 5S battery used by the 99mph Furibee DarkMax or 166mph VXR190, and 6S battery used by the 145mph Speedy Gonzales.

All FPV Racing Drones have a frame with arms that run from the central body to the outer motors, but these arms block thrust generated by the propellors. Some frame designs offer improved aerodynamics by tilting the arms to follow the direction of thrust, whilst moving the bulky ESCs off the arms and into the central body (e.g. Karearea Talon & Stigg 195). With a 4S battery, the aerodynamic Stigg 195 (above) reaches 128mph. However, off-the-shelf aerodynamic-frames are over twice as heavy as the lightest FPV Racing Drone frames, reducing manoeuvrability on the race-circuit. To improve aerodynamics without reducing manoeuvrability, you can choose an off-the-shelf frame with thinner arms (e.g. Hyperlite Floss 5 or Twig V2) or construct a custom VX-series drone frame out of carbon fibre tube and sheet, capable of a world-record 166mph (full parts list HERE).
