Finished my indor winter build early this year. I really enjoyed making the custom battery/cap holder, it keeps the wires out of the way of the ducts. This is pretty much the iflight A85 build except for the flight controller. It was a little difficult since the iFlight 20a AIO board is a little smaller than the JHCMU AIO. If any one knows how they got 6min of flight time on the video Iflight posted please let me know. The most I can get is 4min on a GNB 520 4s and I am running bidirectial dshot. Aslo if you are looking for a Caddx Nebula V2 camera make sure the serial number starts with a "N"
