Hi, I professionally build freestyle and racing quads for fun as I love to fly. This build I have to say turned out real nice, very little if any oscillations with no video noise whatsoever. Running Betalfight 3.3 with all notch flilters turned off including d- term notch with Dynamic Filtering enabled the flight is top notch, smooth and crisp. I built, flown and tested this quad around the beginner to intermediate pilot getting into FPV for the first time. The frame is a true Lumenier frame, not a clone from China, which means the carbon fiber is of good quality, less likely to delaminate in a hard crash. Easy to maintain, access all electronics if the need be without even taking off top plate. With a 1300 Mah battery double strapped to the top the CG is near perfect. Flips and rolls are done with great ease. Truely a nice 4" build if you are in the market for a top quality quadcopter, professionally built, and tuned, ready to fly out of the box look not further. If you like this build it is up for auction on Ebay: https://www.ebay.com/itm/222969005294?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
