For this reason the PDB you choose should contain voltage regulators or BECS (battery eliminator circuits) to provide you with the power output you need!Ĭonnector Locations - Your typical PDB provides connections for your battery, connections for four ESCs and then various low voltage pads (often 5V and 12V). Voltage Requirements - Components such as your flight controller most often require 5V to run off, some cameras may require 12V. I would always recommend you look at the pinout for your chosen board to make sure that it has connections for everything you need. For a first build you may not have to worry about these but for more feature rich drones you will need to make sure you have enough UART ports for what you want to achieve. These devices include receivers, stand alone OSDs, telemetry systems and controllable video transmitters. UART Ports - External devices are often connected to the flight controller through UART ports. I would highly recommend an OSD however they can also be run separately to the flight controller or onboard the PDB itself. OSD (On Screen Display) - Flight controllers with an OSD chip onboard are capable of displaying all kinds of useful information on your video feed such as battery voltage, current draw and even an artificial horizon. The Betaflight F3 is a great example of an all in one flight controller. The only negatives are that they are normally more densely populated giving you less room to solder wires and often require connections on both sides. The older F1 chips present in the CC3D and NAZE 32 boards are now outdated and will not be supported by future software updates.Īll in One or Separate - Many modern flight controllers are incorporating the PDB into the flight controller itself! This is great for tighter builds as you only need one board in the stack and wiring is simplified. The F7 chip is slowly coming in however we are not really making use of it yet. Processor - at the heart of all flight controllers is a micro processor that works hard to keep you in the air, we are only really using F3 or F4 chips so I would recommend choosing a flight controller with one of these. A 3" setup for example will have a much higher kv rating when compared to a 5" design. Generally speaking going higher requires either a big powerful motor or an incredibly light setup. Going low gives you more torque but less top speed and going higher will increase your top speed at the price of torque. Selecting the kv value is like selecting a gear in a manual transmission. KVĪnother factor to consider is kv, this stands for the motors velocity constant which means how many RPM per volt your motor can give for example a 2300kv motor at full throttle on 10V would be spinning at 23000rpm. This could be useful in the case of a heavier quad or when running heavy props. In terms of performance higher torque allows the motor to hit it's target speed faster increasing the feel and response of the drone. Basically the larger these numbers are, the higher torque the motor is able to produce, think of it like engine size with the drawback of larger sizes being the weight. The first point is the size, a motor size is typically noted in a XXYY format with the first two digits referring to the stator diameter in mm and the second two being the height of the magnets. Any thinner than this will break too easy. For many frames 3D printed options are available.ĭo you want swappable arms or a one piece design? Swappable arms can reduce downtime but also increase weight.Ĭan I fit all of my components in that space? Do you see space to mount all your components, this could limit you options later down the line.įor 5"+ frame sizes you should be looking for at least 4mm thick arms, for 3" - 4" you can go down to 3mm and for 2" just 2.5mm. Is there an spot to mount a HD camera? - If you want to carry one of course! Race drones normally opt not to due to the extra weight. The closer the centre you can make it the smoother your drone will fly. Top mounted or underslung battery? - This will affect the center of gravity but could leave the battery more vulnerable. A Freestyle drone typically requires more protection as they are often flown higher and over harder surfaces. ![]() Freestyle Drones however fly better with a little weight as it allows them to carry momentum through various stunts. Light weight racer or freestyler? - Racing Drones are typically minimal frames that are light and nimble.
