RE: cap 580 flatout
i tried the 12x6 prop on my 4100kv yak54f and it flew like it was heavy and landed real hard even sounded weird!...........i dont know why e-flight recommends the 12x6 with the 4100kv ...but i found that the 11x8 which is the prop i used in the first place is the best one for the 4100kv....
now the 1000kv rimfire needs something way smaller so the 9x3.6 is the prop that makes this cap580 land soft and hover still .............right ? Emo are you happy with the cap580's ability with this prop & have you tried any other sizes on this bird?
