I grabbed two of the Vannystyle Mini frames while is was in the U.S. While I am not in the need to comply to sub 250 in Europe, I wanted a small footprint for the O4 platform. The Mini checks all the boxes. The design is well thought out, each part of superb build quality and most importantly, it flies great. Just a caveat regarding the double antenna mount. One antenna broke right on the first small crash. I remixed protective shells with the mount's STL file which provides way better protection, since O4 antennas come at 19$ each. The antenna shafts cradle the RX perfectly on top of the AU. I highly recommend master Vanover‘s Mini frame.
