TUSHEV I wandered the same question. I am putting together a new frame that is capable to fit up to 9” props. I bet this motors in his 1200kv version will be happy spinning 8 and 9 inch propeller, on 4S I mean, may be 5S. I am going to use all in one Xrotor F4 G2 stacks. I ordered my motors directly from Brothers Hobby. The numbers look fantastic so far, it’s going to be around 450grams, just a bit heavier than 6” build!
