    Hi. New to rc planes. Have a STEM club and questions.

    Hi all. My STEM club is making some tiny trainers. I have a question. I have some 2300kv 2204 motors, and a 30A esc. 3s battery. I put a 6045 prop on and I have a horrible screeching sound.. . please see the video. No problem with a 5030 prop...Any advice would be greatly appreciated ...
