Blade grip measured to 14.1mm, bolt hole diameter is 5mm. Weighed them to be 190.4gr and 190.8gr so almost perfectly balanced from a weight perspective. Checked COG matching which was off between the blades around 5-6mm so you will want to balance them and check COG matching. Very stiff blades, almost completely flex free. Weight is concentrated in the front edge of the blade, and COG is outwards the blade from the middle a few centimeters. Finish so-and-so on one blade (smudged white paint, white protruding blob of paint on one place), quite good on the other. For the price not bad. Will be interesting to try on my 700e FBL.

I have a set on my Trex 700 nitro. Head speed is about 1800 RPMs. Ithink they are great Although I'm a lightweight pilot, others who are far more advanced haves tested out my heli with no complaints. I would say give them a shot.

Very nice blades. I'm suprised by the high level of workmanship because of the 40 odd dollar price. Balance is perfect. They are stiff but light. 183 grams each, 14mm root. Not as pretty as a Radix blades, which they replaced after a crash, but I couldn't give a crap. At 25-35% of the Radix price these are unbeatable. I can't believe, after a boom strike, that a carbon boom and TT will cost more than a new set of main blades. Thanks HK :)
