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.

Comfy and supportive
Love it! Very snug and supportive. I am 5‘6“ 188 pounds. I am wearing a 34H and it fits perfect. Will definitely be adding more colors to my collection. Hopefully they add the HSIA Delia collection that are similar to these, but have printed options.

Good value, fantastic fit
Color: Grey Purple, Size: 38D
Very comfortable lingerie, gives a smooth look under clothing. Very satisfied with this purchase. I have purchased bras at higher price point, these are comparable. Good quality and value for the money.

Very Good strong material
I love the bra but story time, I initially got a 38DDDwhich is or was my size however I wore the 38DDD all day at work (RN) and the bra did hurt my sides like the sides were possibly too tight and digging into my ribs BUT the support was amazing and the minimizing was PERFECT I looked almost 2 cups sizes smaller in my opinion but I figured something was off so I ordered a 40DDD got those and the side digging wasn’t there but I lost a little bit of support maybe or I could have just done the straps wrong because it was a quick try on but overall I love the slimming effect and the material is soft and I truly appreciate this bra. The material is STRONG not cheaply made very beautiful over all. This is a good quality bra once I figure out the correct size . I ordered another 38G to see if I noticed a difference and a 40G to see if my cup size is wrong all together (which is what I think it is more so than the band size) I tried another brand and the 38 band was find the cup was too small in 3 different brands. Guess I’ve gained some weight but overall even with the pain for the side digging I could tell this was a GREAT bra. Just measure yourself correctly lol
