尽管被周围无副翼应用而设计，这些刀片可以在标准的平衡翼的直升机模型，以及使用。传统的平衡翼直升机模型中使用时，他们擅长的FAI / FC3风格飞扬。
Hi guys, Not a bad blade at all, these blades weigh about 65,4gr and were 0,2grams out. The paintwork was almost perfect. They fly a lot better than the standard blades that came with the HK500heli. Infact when you bend the old one you can hear it cracking on the inside, absoluut rubbish.I have been flying my Trex500DFC with these blades for over a year now. I can only say: Perfect. I fly FAI style aerobatics and generally hoon around with the great little Trex.
These are indeed B-chi=oice if you count the really minor paint fault that can only been seen up close.
Value for money: Absolutely. I've just bought 3 sets more.Very good blades, I will by only this in future. I usually balance them down to 0,xx gram with not more than few cm of tape.Outstanding blades for an outstanding price. These blades feel very locked in. They fly heavier than the Revolution FB blades but they feel lighter. Not as much blade noise as the Revolution FB blades.Disapointed with these blades. The finish on them are not as good as the TIG blade for a few $ more. The clear has bubbled, but are usable. The weight were not even and like they said the writing is smudge.
Will not buy these again.Perfect for Flybarless use.Excellent! So glad I got two sets of these. Not only do they look fabulous, but they fly amazing. Very stiff and a good weight for FBL. The finish good enough for me. No complaints. I hope HK gets the 520mm, as well.
