Guys..I got an email from hacker,and they said..like this...and same with you guys has explained to me..

Dear Mr. Okytriwibowo

Thank you very much for your mail. The A50-16l with 10S lipo and the APC-E
16x8 will be a good setup. The current in this setup is ~54A.With more cells/voltage the prop has to be smaler. Otherwise the current

>>> less cells > larger prop
Best regards.
