Drones

Camera drones, FPV quads and the selfie drone that fits in a pocket:

they look alike in photos and fly nothing alike. A camera drone from DJI’s Mini, Air or Mavic lines locks onto GPS, hovers hands-off, flies itself home when the signal or battery runs low and keeps its camera level on a gimbal. An FPV quad is flown by hand through goggles, with nothing holding it steady. The DJI Avata is the ready-to-fly way in, with guarded props; a custom freestyle quad is assembled from a frame, motors, flight controller and video transmitter. Palm drones like the DJI Neo launch from your hand and follow you for a clip. Among remote-control models, only a drone with GPS can be left to hover; a cheap one without it drifts off on the first breeze.

The Mini, the Air and the wind off the Pacific beaches:

weight is where first buyers go wrong. A featherweight Mini packs easily for a beach weekend, but in the steady dry-season trade winds it fights to hold position and can struggle to come back upwind on a low battery. A heavier Air or Mavic holds its line and films steadier, at the cost of bulk and price. Albrook airport sits on the edge of central Panama City, and DJI builds airport zones into its app, so a DJI may warn you or refuse to take off in the neighbourhoods around it; a custom FPV quad has no such fence. For FPV, the goggles and the quad must share a video system, analog or digital, and the systems do not mix. The radio that flies a custom quad can also fly RC airplanes once the plane carries a matching receiver.

Drone generations and how fast they lose value:

new, a palm-sized selfie drone starts around $250, and a folding camera drone kit with obstacle sensing and spare batteries runs past $1,000. Used, age counts for more than wear. DJI brings out a new generation of each line every year or two, with a better camera or fuller obstacle sensing, and the model it replaces loses value the moment the new one lands. A kit one generation old, with its controller and batteries, changes hands around $550 to $750. Two generations back, or on tired packs, it fetches a good deal less, and new batteries become the next owner’s first expense.

Account locks, gimbals and flight records on a used drone:

start with ownership. A DJI stays tied to its owner’s DJI account, and while it is still bound to the seller it may restrict or refuse your flights, so have them release it in the DJI Fly app while you watch, and check that the serial number on the airframe matches the box and the app. On power-up the gimbal should run through its start-up wiggle and settle level; a camera that twitches, droops or throws a gimbal error has usually taken a knock that damaged the ribbon cable behind it. The flight records show total hours, and the battery menu shows each pack’s cycles and cell balance. On a custom FPV quad, look for split carbon arms, bent motor shafts and scorch marks on the video transmitter, which burns out fast if powered without its antenna.

Passing on a Mini, an Avata or an FPV build:

screenshots do the selling. Post the battery screen with each pack’s cycles and the flight-record totals, with photos of the lens and the serial number. Say which controller and how many batteries come with it, and whether it has crashed or been repaired. Keep the receipt with it, since it shows the drone is yours to sell. For an FPV build, list the video system and receiver protocol so a buyer knows it will pair with their goggles and radio. Hand it over somewhere open, a field outside Penonomé rather than a rooftop near Albrook, fly it for the buyer, and unbind it from your account in front of them once the deal is agreed.
