I bought your helicopter Walkera v370d01. Lightweight blades, but fragile. But for my money this is a good buy.
Walkera v370d01. , . .Really bad blades. They flex a lot and even doesn't have enough lift to hover the heli. I used them on honey bee V2. Bought 6 pairs - wasted money...it will work on the UFLY. the blade is little more flexible than the stock ufly blades and much wider. you can easily match it up with the ufly blade and cut the trailing edge to match the ufly blades. it will fit in the ufly blade grips but you need to use the donut adapter from the ufly blade. i need to dbl check if it will work on the hbfpv2.Unfortunately, I ordered 5 sets, thinking wow! what a deal.. Alas they're soft and unusable to me and my Walkera 4# metal version (no lift), they also have very sharp edges.. Pity.
