Fiala is the only 4-stroke company in the world which produces both the engines and the propellers developed and designed to be used with them. They go hand in hand.

The Fiala propellers have quickly become a staple in the global UAV industry as no other propeller matches their efficiency.

Hence it is important to run the Fiala propellers with the Fiala engines should you want to run the diameters and pitches shown in the Fiala manual. These specifications are based only, and I cannot stress that enough, on their purpose designed and built Fiala propellers.

Other brands run the risk of over torquing and stressing the engine unnecessarily, limiting performance and service life.

Just buy them. There is nothing not to love!
Color: Beige Tortoise Frame / Brown Gradient Lens, Color: Beige Tortoise Frame / Brown Gradient Lens
I've had these for a year or two now and came back and ordered three more. I wear these daily because they are so comfortable and cute. A lot of sunglasses give me headaches either they are too tight or too heavy, these never do. They don't catch in your hair if you put them on your head. They don't slide down your nose when you sweat or move your head. The beige tortoiseshell is the prettiest most flattering color ever. I'm a dark winter and I struggle to find cute sunglasses other than black. So many are brown warm colors the beige violet tortoiseshell is very cool and flattering for my cool toned gals. I have a pretty normal size head and these are just a hint of oversized but in a good way. I have an oval face that leans long oval or slight heart and these are seriously flattering. I have so many photos in them they always look good. I'm going to try the all plastic version too but I honestly love the thin metal arms. Just buy these it's such a good buy and brand. I literally donated other pairs because I don't wear them anymore after discovering these. I bought obviously the beige tortoiseshell, black with gold, and the cherry. Debating on the green. My only wish is more color options. I'd love more silver arm options. Thanks WMP for these!

Cute but wide
Color: Tortoise Frame/Brown Lens
cute sunglasses that look nice on but are a little wide for my more narrow face. They do fit well enough for me to wear, it’s just they’d definitely fall off if I lean down in them. I think I’m going to keep them though. Construction wise, they are nice, very light which makes them more comfortable and the tortoise color is pretty. Overall nice sunglasses for the price.

Perfect shades
Color: Tortoise Frame/Brown Lens
I love these sunglasses! I have a small face, and I find that these fit perfectly! They are stylish, fun and I don't have a problem of them sliding down my nose.
