I managed to get 28 mins flight time on the 18650 4S pack with SMO4K camera powered from the same battery. And I love the fact that I can use my Lipo 6S batteries as well. But flight time is much shorter on LiPO. I get 5-8 mins on 1300Mah 6S. It seems it tuned better for flying on 4s. The footage I get with a 4S battery is smoother. It's hard to find these 2mm shaft hole props in stores. Overall it's a great quad for long-range cruise flying. And you can do some freestyle on it when powering with LiPo batteries. The most unpleasant thing happened to me with this quad - the BAT soldering pad came off instantly as I touched it with my solder iron tip. Out from the box the quad has wires for connecting GoPro naked camera. I was going to re-solder SMO4K connector and solder pad came off. The Banggod support only proposed to sell me a new flight controller with a $2 discount. And HGLRX support replied, "we are sorry about that". From my personal experience, Diatone makes better and more reliable electronic components than HGLRC.
Package well packed and received very quickly. Very good FPV long rangel drone that perfectly meets my needs. To recommend. Thanks again to Bangood's impeccable service!
