skrnrhrery The Propeller Blades, UAV Propeller Used to Remote Control The Glider Special Nylon 46 Mm Blade Shaft 0.8 Mm of Positive and Negative Mini UAV Propeller Aircraft Parts

Great value for a beginner drone operater. Have plenty of blades for replacement when you crash

Amazon referred me to these when I was looking for replacement propellers for my Spacekey drone. Those propellers are 55 mm with a needed aperture of 1 mm. I can't seem to find the replacements for Spacekey drone, the ones I purchased before are out of stock.

These fit and work well on Holystone HS177. They are very fragile though and break constantly.

Got these for my rc plane and they fit well and work good!

Only wish they came in two colors to help with orientation when flying

I bought these based off of a review that stated these fit the kids UFO drones. These definitely do NOT fit them! They are too big. Only writing this so others looking for replacements for kids ufo drones don't waste their money

Picture shows 20 blades. We received 8.

Probably should have measured the size they were a little small for what we needed.
