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.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!
