The blades are identified for the DJI Agras T20 and T16, and they are the parts operators look for after a blade strike, a chipped or split tip, or a rotor that has started to shake the aircraft. People usually search for them as a T20 propeller, a T16 3390 propeller, a T20 CW CCW blade, or a T20 folding propeller replacement. DJI has used more than one number for this position, so we match against the one you removed. The point most worth knowing is the count: a pair is one blade of each rotation, not two blades for one rotor.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

Each one bolts at its root into a propeller clamp on top of a motor, pivots on that bolt, and swings out to its working position under rotation. Folded back, the blades lie along the arm for transport.\u003c\/p\u003e\n\u003cp\u003eThe pair is easiest to understand from what is on each blade:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe root\u003c\/strong\u003e — a thickened hub end with a round pivot hole, which takes the bolt that holds the blade in the clamp and lets it fold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe working span\u003c\/strong\u003e — a black aerofoil that widens out from the root and tapers again towards the tip, with a twist that sets which way the blade has to turn to lift\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe orange tip\u003c\/strong\u003e — a coloured tip that makes the disc visible to people on the ground when the rotor is turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe QR-code label\u003c\/strong\u003e — an identification label on the blade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe rotation is built into the shape. A CW blade is the mirror image of a CCW blade: the same root, the same length, the same outline seen from a distance, but the twist and the leading edge run the opposite way. On the bench they look like a matched pair. On the aircraft they belong on different rotors.\u003c\/p\u003e\n\u003cp\u003eOver a working season the blades take:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStrikes against crops, branches, wires, posts and the ground during low passes and landings\u003c\/li\u003e\n\u003cli\u003eContact with vehicles, trailers and people during handling with the arms unfolded\u003c\/li\u003e\n\u003cli\u003eSpray and wash water across the whole span on every flight\u003c\/li\u003e\n\u003cli\u003eDust and grit carried in the downwash, which wears the leading edge and the tip\u003c\/li\u003e\n\u003cli\u003eFolding and unfolding at the pivot every time the aircraft is packed and unpacked\u003c\/li\u003e\n\u003cli\u003eSun and heat on the trailer between flights\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBlades come out for one of three reasons: visible damage from a strike, wear at the leading edge and tip that has built up over many flights, or a pivot that has loosened so the blade no longer sits where it should. The first is obvious. The other two are found by looking, and by knowing which blade belongs where.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe blades' engineering role is to produce thrust from motor rotation, evenly, in the direction the flight controller expects for that rotor.\u003c\/p\u003e\n\u003cp\u003eIn the propulsion system they:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConvert motor torque into lift for the rotor they are fitted to\u003c\/li\u003e\n\u003cli\u003ePush air down through the spray zone, which carries droplets into the canopy below\u003c\/li\u003e\n\u003cli\u003eBalance each other across the rotor, so the motor turns without shaking the arm\u003c\/li\u003e\n\u003cli\u003eFold back at the pivot for transport and swing out under rotation for flight\u003c\/li\u003e\n\u003cli\u003eMake the turning disc visible through their orange tips\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat the blades do not do matters as much:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThey do not set which way a motor turns; the motor and its controller do that, and the blade must match it\u003c\/li\u003e\n\u003cli\u003eThey do not hold themselves in place; the pivot bolt and the clamp do\u003c\/li\u003e\n\u003cli\u003eThey carry no wiring and have no electrical function\u003c\/li\u003e\n\u003cli\u003eThey do not fix a motor fault, a bent motor shaft or a worn clamp\u003c\/li\u003e\n\u003cli\u003eA CW blade does not become a CCW blade by being turned over; it is a different part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe T20 and T16 are six-rotor aircraft. Half the rotors turn clockwise and half counter-clockwise, so that the motors' turning forces cancel and the aircraft can hold its heading. Every rotor carries two blades, and both blades on a rotor turn the same way. That is why the blades are sold as one of each rotation: the pair is a unit of the aircraft, not a unit of a rotor.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — a pair is one blade of each rotation, so count what you need by rotation, not by pairs\u003c\/h2\u003e\n\u003cp\u003eMost blade mistakes are counting mistakes. An operator with one broken rotor orders one pair, opens it, and finds a single blade that fits that rotor and a second blade that belongs somewhere else.

The labelled pair makes it look as though a pair is what one rotor needs. It is not. A rotor takes two blades of one hand; a pair is one of each.\u003c\/p\u003e\n\u003cp\u003eDoing that count first saves a second wait. Count the damaged blades by rotation: so many CW, so many CCW. The larger of the two numbers is the number of pairs that covers the job, and the difference is what goes into the spares box. A full aircraft is twelve blades, six of each, which is six pairs.\u003c\/p\u003e\n\u003cp\u003eGetting the hand right matters more than getting the count right. A blade of the wrong rotation can bolt into a clamp, because the root is the same, and it will then push against its partner instead of with it. Holding each new blade next to the sound blade on the same rotor takes seconds and settles it.\u003c\/p\u003e\n\u003cp\u003eA damaged blade is not worth flying on. A chipped edge or a cracked root unbalances the rotor, shakes the arm and the motor bearings on every flight, and can let go entirely. A blade is a small part to replace against what a rotor failure over a field costs.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.
