► What you need to pay attention to when choosing a propeller for a race whoop:

● Pitch → For me low pitch because of my high kv motors
● Number of blades → For me 3 or 4Blade (2blade only on crazy crazy lightweight builds)
● Surface area of a propeller → For me bigger surface area
● Shape of the propeller tips → I don`t care to much about this (thin tips are less durable)
● Height of the propeller tips → Not every frame/motor/prop combo is possible!
● Weight of the propeller → For me lower weight is better
● Durability of a propeller → I don`t care to much about this if the performance and weight is good
● Color of a propeller → I prefer bright colors in case I lose a prop
● Propeller balance → For me the propeller has to be well balanced from the factory
● Shaft diameter → I prefer 1,5mm if possible. 1mm on rcinpower is also ok (good material)
● Flight stability → I prefer 3 and 4Blade props for higher rotational mass and stability in flight
● Noise of the propeller → 3 and 4blade props are definitely better to protect the ears of the neighbohrs



► My favorite Whoop Propellers for my high kv Racing Whoops in 2024:
(As of 5/10/24)

2inch (51mm) Propeller for 85mm Race Whoops:

1. HQ Prop T2x3x3 (best feeling in flight)
2. Gemfan 2023 (most efficient, good for some frames because of the higher propeller tips)
3. HQ Prop T51MMx4 (Lightweight, interesting flying feeling)
4. Iflight defender 2020 (Leightweight but not very durable, only for very very lightweight builds)

40mm Propeller for 75mm Race Whoops:

1. HQ Prop 1,6x1,6x4 ABS (not durable, but lightweight, great precision, low pitch)
2. HQ Prop 40mmx4 (low pitch, for lightweight builds)
3. HQ Prop 40MMx3 (low pitch, good as durable alternative to the nr 1)
4. Gemfan 16083 (medium pitch, good for outdoor)

31mm Propeller for 65mm Race Whoops:

1. Gemfan 1219S (lightweight, good grip in the air)
2. HQ Prop 31MMx3 Ultra Light (not testet yet)

⚠‼⚠Keep in mind propellers are very sensitive to discload! A propeller can be great with an all up weight 75mm whoop weight of for example 36g. But at 37g it's not so good anymore and at 38g it's not good at all. Propellers are sometimes only good up to a certain weight or in other words disc load. My information only refers to my whoops, which are very light and have a lot of power. I fly high kV motors with low internal resistance, without motor plugs (motor cables soldered to the pads on the flight controller), AWG20 main cable on 75mm whoops (lower internal resistance), BT2.0 or A30 main plug (lower internal resistance and good contact) and with the best lipos I can get (highest CRate)! This is all very important! If you want to benefit maximally from my experience then I advise you to do everything like I do. (For example, build my Butterfly75 802 27k Whoop)
Keep this in mind my friends!

⚠‼⚠Keep in mind: When choosing a propeller (for whoops) there is no point in using theoretical numbers. For example, it's of little use if you try to calculate something with the kv of a motor if the manufacturer has written an incorrect kv number on the motor (often happens with whoop motors). Or if you try to calculate something with a stable 4 volts (at 1S), but in reality you have voltage sag from the battery and you are flying with 3.8V shortly after takeoff. That's why you have to test it yourself if you want to have the maximum. Or you can rely on my experience and build a whoop exactly like I did. Then you will reach maximum performance more quickly and can focus on practice to fly.

⚠‼⚠ If you crash a lot and you are forced to use motors with 1mm shaft out of bad material you can use a ABS Prop or another soft prop as the intended breaking point to save the motor shaft. Or you can use a two bladed prop.

⚠‼⚠You don`t like to tune your whoop? Use 3 and 4Blade props with high kv motors and you are good to go! (stock tune is fine)

I hope this video helps you. If you have any questions, I'll be happy to help you. (It is important that you give me as much information as possible! Otherwise I can't advise you.)
I will reply to comments within a maximum of two weeks.

Happy flying my whoop friends!
