Master Airscrew Q-Tip Propellers

Yesterday I received Master Airscrew Propellers. Apart from the premium packaging they look like any other normal propellers and are made from plastic. There were only 2 colours being sold on eBay: green and orange, I opted for orange.


They came with some screws and a tissue! I thought “no, I have to screw them on”. But it turned out that they are not needed. I think the reason for the screws is that they can also be used with other makes of drones where you do need them.

The props are supposed to be perfectly balanced, more efficient and quieter. I can’t check whether they are perfectly balanced, but upon closer look you can see why they might be more efficient and quieter than normal propellers.

They have, what is called in aviation, a Q-Tip – a slight kink at the end of the propeller. This is to control the air spillage over the propeller tip. In theory, it delays the tip vorticies, which cause drag and turbulence. A propeller, like a wing, works best when it has unturbulated air over the airfoil sections. The Q-Tip delays the vortices, the propellers then have smooth air,  making them more efficient and quieter.

As I mentioned before I bought them on eBay for £29.99 and I hope that the reason for such a high price is not only because they are made in the USA.

I didn’t have a chance to test them, the weather over here in the UK is awful, but if what the makers are claiming is true,  I would give the propellers 4/5. One point knocked off for being way too expensive.

May the force be with you!
