Winds at less than 5mph. GensAce 3S 25c 1550mAh LiPo, HeadsUpRC Power Up 400 Sport Outrunner motor swinging an Art-Tech 10x4.7 SlowFly Prop, Spektrum AR6210 R/X via Spektrum DX6i T/X. Continuing to dial in this bird....can fly like a butterfly or steady as an Eagle. This is a very light set up at or near 22.30oz total flying weight. COG is perhaps a couple mm aft of recommended placement...will probably keep this COG for light airs and move forward for windier conditions and heavier battery. Very realistic in the air and if flown carefully is very graceful and lifelike....recommend this slow flyer to intermediate pilots perhaps a little too twitchy for novice flyers.
