pool finish holes filled with glue can not flyVery poor blades. First I ordered 2 pairs. both are absolutely terrible: Both pairs have wounds and scratch on surface with many other small defects making the blades unusable.
Then I tried 2 additional pairs. One did look OK at first view and the other has geometrical defects making it unusable. So I tried the only one of 4 pairs that looks OK on my KDS innova tdt 700. Blades were balanced well, I fine tuned the tracking and gave it a test flight.
At strong hi acceleration maneuvers, the rotor disk is no longer a nice disk and a tracking problems is clearly visible. I landed at once and detected the problem: One blade is less rigid then the other causing it to flap and bend more during demanding flight times.
Just for the test, I took 1 pair of a leading firm to make sure it is not something with the helicopter and then it was fine.
Bottom line: stay away from these blades.These blades are HORRIBLE. They are NOT quality of any kind, much less high. The finish is dull (like they were wiped with thinner and left to dry) and the are covered in blisters and pits. The blades I received have pitting around the bolt sleeve. I would expect much higher standards for a 690mm blade, even at this price. I am in the process of getting a refund/exchange for different line of blade. Id try woodies before I flew this crap.The finish on mine was not good so 3 stars on quality. There was a lot of scratches on mine and the finish on the white paint is not great. Some small spots where there is no paint so you can see the carbon under it and the white edges are not sharp because the paint got under the masking during painting. They are like new but "cosmetically defective". I sanded the scratches with 1200 wet and dry sand paper and buffed them up with polish so they are good enough now.
They are balanced "ok". I used white insulating tape and it went 1.5 times around one blade in the center of the blade with 1/2 around the blade on the tip to get C/G and balance right.
Other than that they are good especially for this money and they are straight and true and strong.Very qualitative blades! Analogue Radix V2. On balancing it is possible to come to the conclusion that it FBL blades!!! Weight of the blade of 173 gram only. It is very happy! HK - good fellows!Gzel bir rn kaliteli ve tavsiye ederim...
