Just finished testing these 2 builds and i'm really impressed with the performance! these 1103 8000kv motors are perfect for these props running this light weight 2s 300mah battery. i cant say i recommend these batteries because i'm sure there are better out there and these are all I've tried so far. but i tuned these to match the weight of this. Its amazing how even just 2 grams makes a difference in how it performs! If this had HD video this would be the most perfect quad ever! but that would add weight and wouldn't perform as nice.. If your planning to build one like this make sure to keep the weight low!! these 2 are around 59 grams all up weight! One has the runcam nano 2 and the other with brighter colors is the runcam racer. Both i love! one has the crazybee board and the other has beta fpv board.. keep in mind that one of these cameras is pal and the other ntsc so there's some frame stuttering because the timeline is only 25 fps
