I have had the 2950kv version in gun metal and gold for a few years now. Still no issue with these running HQ 5″ water melon 3 blade. favorite prop was the HQ r36. I have run many blades but kept them under 4″pitch as the motors are still small for a 5″. the quad with a 4s Dogcom 1300mah U-cell weighs 440g and gets 6mins – 9mins aggressive flying. while the quad is not as powerful as a standard quad it gets to 92mph no problem and is far far more agile out maneuvering any standard 6s quad. would note don’t pay any attention to Rc-InPower’s spec sheets (more sales pitch than truth). these were the biggest most powerful motors with a 5mm nut that would fit a 2fiddy that I could find.
