My favorite prop for 3 inch frames
I've tried quite a few 3 inch propellers over the past few weeks.

Since I also sometimes fly with heavy frames (digital) up to 300 gr., It doesn't make it easier to find the right prop. I have flown many brands and propellers from 3x3x3 to 3x5,1x3. Zt also tries to find a setup via the Pid's if the base slope fits so far.

In the end, I got stuck with all 3 inches at the HQProp Durable 2.9X2.9X4 Gray. They leave more (albeit minimal) air to the frame, consistently had the least propwash, and simply run good-naturedly. The pitch / power corresponds approximately to a 3 x 3 propeller with a 4-4.2 pitch.
With 3600 - 3750 KV engines with 3S / 850 mah, Cinematic flight style includes a good 5 - 6 minutes of flight time, despite the 280 gram flight weight.
The whole thing with 4S / 850 mah, then offers enough power to have fun with freestyle at 295 grams.

If you are looking for a good-natured / round 3 propeller and previously traveled in the area 3x3.6 - 3x4.3x3, you should try a test.

Great for Cinewhoop
I designed a Cinewhoop completely myself and made all the parts myself, but the big problem was the volume of the propellers caused by the ducts. Unfortunately, all Cinewhoops have that. With these props I was able to significantly reduce the volume again compared to the HQ3X3X3. The only drawback, they are not quite as stable as 3blatt, feel more delicate. Doesn't matter to my cinewhoop with ducts. Will buy it again

HQProp Durable 2.9X2.9X4 Gray
The HQProp Durable 2.9X2.9X4 Gray propellers are beautifully made. Can be easily mounted on the engine and has good flight behavior.

Deliver a lot of thrust
Have the props on my DC3, deliver more than enough thrust and are very break-proof in the event of a crash.
