The Gemfan Master series of propellers is the next evolution in propeller design. Gemfan has utilised the feedback from the top drone racer pilots to develop these incredible propellers. Whilst we say they are unbreakable I am sure some of you will prove us wrong!! but they are very very tough.

 

The Master series are manufactured from the same material as Gemfans "Unbreakable" or "PC" series so they will take all the knocks and bangs you come to expect when racing. Supplied 4 in a pack, 2 x CW and 2 x CCW and they are also pre-balanced to reduce vibration to an absolute minimum.

 

Specs:
Diameter: 5"
Pitch: 4"
Blades: 3
Hub Internal Diameter: 5mm
Hub Thickness: 7mm
Color: Chrome
Quantity: 2 x CW, 2 x CCW

I bought more

May 07, 2017

I bought some more of these because I like the chrome, I mean I REALLY like the chrome. The effect is super cool in flight, and they perform quite well. To call them unbreakable is not accurate at all. In fact, I've never had a set of these survive even a mild crash. They break when most props would just bend. The performance is good, the look is awesome, but they are more fragile than the average prop in my opinion. Having said all that, I will probably buy more because they look awesome, and try and crash less. :-)

Nur für Standmodelle oder zum schweben geeignet

Hi zusammen,

leider sind die Propeller nicht aus Polycarbonat und auch nicht unbreakable....

bei der kleinsten Berührung splittern die Propeller in tausend Stücke.....

Not Quite Unbreakable

Apr 15, 2017

I am pleased with the performance of these props, and I really like the chrome; it has a really cool effect during flight, especially at night. They perform as well as any quality 5040 prop, but I expected the to be a bit more durable given that they call themselves "unbreakable". Obviously nothing is unbreakable, and they address that in the description, but after just one minor crash, I busted a prop. I'll probably buy some more because I really like the chrome, but if I find some more durable props that offer chrome, I'll probably leave these behind.
