Besure to check your CG before flying and the littles amounts of weight forward or back will affect the stabiliy. I used a 2S 850mah and 1000mah just fine, long flying time and can climb to nice altitude to glide back down. Will try a 3S lipo soon as the speed was fast to stay fun but could of course use more power=speed. I did change the folding prop to a 9x5 since I broke the stock 8x5 prop [my fault]. It does provide a little more power since I'm only using 2S and no issues with weight.
Start on low rates first because it will be twitchy, took about 3 flights for me to learn its flying characteristics.
