Hi everybody, I am a "hardcore newbie" in quad racing/acro. Most of my droning experience is with the DJI Spark (love that drone). This is the kind of photos I like to take: A friend of mine convinced me to try out an EMAX TinyHawk and I absolutely loved it. However, I was also frustrated for many reasons: first, the TinyHawk user manual was terrible. Second, it seems that it is a must to use Betaflight to configure the drone. I had a friend do that for me since Betaflight has no useful documentation and the little that is out there is way above my level. I tried a Mobula7, but I could not even bind it to the RC. After doing a lot of research on the Internet and various fora, I got myself a F210 RTF kit! Got it today, so I did not test out the drone yet, but I hope that if I run into problems, I can come here for help. I will begin with two basic questions: 1) does Walkera have a US-based customer support website or phone? I could not locate any. 2) I ordered what looks like spare props for the F210, but they have three blades instead of two. Are these the wrong ones? Their code is: F210-Z-40 and here is the Amazon link to them: https://www.amazon.com/gp/product/B01N27O28G/ can I use these? If yes, which ones are better, 2 or 3 blades? Thank you!
