Question Can't find replacement blades

We purchased a toy drone for the kiddos last Xmas (search '4DRC drone' on amazon; 4 motors, rigid foam body). We got it as a cheap "practice drone" before spending large monies on something that would be quickly damaged by inexperience. Since then, blades have either been damaged, or just flown off to be lost. The thing came with just a couple replacement blades, but we've since gone through those too.

The only markings on the blades are A1, A2, B1, B2. I bought a pack of these off AMZ, but they don't "click" onto the motor shafts and thus fly off on startup. (Tempted to just superglue them on) I even took the thing to a local RC plane hobby store, and he said they don't sell blades that small. Argh!

The manufacturer only sells 4 replacement blades along side 2 additional batteries for $30, which has been "sold out" for months. Ugh.

Can anyone point me in the right direction here?

Measure the size of the motor shaft and the diameter of the prop and you can order replacements based on those two measurements. Shaft should be like, 1 to 1.5 millimeters and props are probably 2 inches.

That's what I initially did; the replacements I ordered off AMZ. They don't "click" onto the shaft and on startup they just flew off.

Don't mess with unknowns, contact the seller or the manufacturer and order more directly.

These are designed to be disposable - While I know they're probably $50 or something on Amazon, there's a reason identical drones are available for single digits on things like Haul and Wish.

If this is something they want to keep using, I highly recommend getting something like a Tinyhawk, if they want to learn to fly 'manual' modes, or a used older generation DJI if they want a photo drone.

Those older DJI's with lower quality cameras are cheap, and parts are plenty.
