Small size propeller used in higher kv motor and large size used in lower kv motor. You can try small propeller watch this https://www.youtube.com/watch?v=SBbej88jX2Y Title: Re: Which propeller to use ? Post by: kiran rc on May 09, 2018, 02:27:34 PM The maximum size of prop a 1400kv motor can take on a 3cell LiPo is 7-8". (Current draw would be around 15-17A)
From the data sheet, 8x4 looks like a good choice. Title: Re: Which propeller to use ? Post by: knvshrm on May 09, 2018, 04:14:41 PM Ordered 8*4.5 as 8*4 props weren't available.
Title: Re: Which propeller to use ? Post by: kn8alpha on May 16, 2018, 01:53:48 PM It depends on the max current that motor can handle. I had a 1400kv 3S setup with 1045 prop but the max motor current was within 20A.
