Had a very short window in the weather to test some props, and was very excited to try out the HQ6x3x3-v1s on my long range quad. The quad is designed for 7" props, and runs a KissCC with Cobra CPL2207/1500 motors.
Prior to trying them, I was concerned that the pitch may be too low to get good cruising speeds, but I was very happy to find out I was wrong! The cruising speed was nice and quick, and there was plenty of agility - it's quite a light propellor so it will react to throttle changes very quickly.
I think the ideal motor & battery for this prop would either be a slightly higher-kV, maybe in the 2000kv range on 4S, or to run on higher cell counts like 5S or even 6S potentially.
The prop is super efficient on the setup I had, with current peaks around 36A overall (only 9A per motor!!) and averaging around 16-17A with my fairly heavy throttle thumb in this video - I was averaging around 60% throttle. Managed 7 minutes on ~1800mAh out of a 2600mAh pack.
I'm looking forward to getting this setup out into the mountains, it's super smooth and was much easier to tune than any other prop I've run on it. And with a real long range location instead of a tight park I'll be able to let off the throttle a lot more and get some decent range.
tl;dr:
I predict that this prop will be great for:
• Long range with 4S ~1500kV
• Mid range with 4S ~2000kV, or 5-6S ~1500kV
• Buttery freestyle with 4S 2300kV - with a large and efficient stator, such as Cobra CP2207/2300.
