Who can give us better details than Evan Turner himself about the characteristics of these props?
Here is what he had to say about the HQR38 on his announcement post.
"It’s been a long time coming, but I would like to introduce the “Headsupfpv R38” prop from HQ! These props take the best qualities from props throughout the market and somehow puts them all into ONE prop! It’s incredibly responsive, has great durability for its weight and has the top speed that most if not all extremely responsive props lack."
