9:40 Outro
► 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 4-Blade (2-blade 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 4-Blade props for higher rotational mass and stability in flight
● Noise of the propeller → 3- and 4-blade 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 1608-3 (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 C-Rate)! 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 4-Blade 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!

This video is pure GOLD😮 It's super rare to run across someone who has tested almost every whoop prop on the market AND they want to share their learnings with others! Thank you so much for being such a valuable contribution to the hobby❤

@butterflyfpv 21 день назад

Thank you so much my friend! I did my best. My English is bad, but I think it should be understandable enough. Yes, I understand exactly what you mean and to be honest, that's exactly what gave me the motivation! I was sometimes frustrated when I saw videos from people who knew a lot but didn't have time for RU-vid (or only made a video of the result, but without any information) or the pilots who fly very well but don't want to share their experiences because they are too competitive. That motivated me, firstly, to try everything out myself and secondly, to collect my knowledge and ultimately pass it on to other people here on RU-vid. And along the way it was people like you who motivated me not to give up! I thank you from the bottom of my heart for that! ❤Together we are stronger than alone and much of what we as a human species have achieved is thanks to the people who, like us, are positive and without hate and without unnecessary copetetive thinking in the wrong place.. I am very grateful for this hobby, the people in it and will try to complete my dream and pass on all my knowledge. Happy flying my friend! Whoop whoop!🥳

Schöne prop Sammlung. Kenne ich irgendwo her 😅 Bei mir ist lückenlos bis 10 Zoll gesammelt. Mir gefällt wie leise die vier Blatt props sind. Zudem sehr griffig und smooth. Am schnellsten sind die zwei Blatt, wenn der Motor viel kv hat bzw hoch dreht. In kurven zählt aber grip und beschleunigen mehr.

@butterflyfpv 21 день назад

Wow deine Sammlung muss crazy sein😱Irgendwie bin ich froh dass ich nur bis 2zoll props fliege..😅 Ja voll am schnellsten sind oft die zweiblatt, aber wie du schreibst, für einen racer zählt topspeed oft weniger als anderes. Darum fliegen heutzutage auch alle 5inch racer dreiblatt. Und bei whoops mag ich vierblatt irgendwie manchmal auch.. die HQ 40mm 4-Blatt in ABS sind die allerbesten! Ich wünschte HQ würde die mal in polycarbonate machen..

I havent finished the whole video when writing this but whoaaa that's a lot of micro props - and some of those are ancient! we've come a long way and it's cool to see the "development" of micro props over the years as they become more popular. Great info as always btw! Lots of great insights I think most micro pilots will appreciate! Might reference your video in an upcoming build video I have (ofc if you allow me to ofc!). This type of information should be shared more often!

@butterflyfpv 21 день назад

Totally. They used to be brand new back in the days ☝🏻😌 now they are oldtimers🤣Yes it was a very long way and it is still a fight with the prop companies. I don't know wtf they think and do sometimes.. But at least we have some good props these days. Yes this would be cool! You can use everything. You can also copy 1:1 etc. Or you can test what I tested for yourself and then make a video on your great channel. I don't need any credits. I'm just happy when the knowledge is spread, people are happy and the whoops become more powerful and more popular.. whoop is the way! whoop whoop🥳

@sticky_ricebowl 19 дней назад

@@butterflyfpv I know! I was just a kid when the first props came out and now I'm in college and we have a good number of variants now! A fight between prop companies is what we need tbh cause we can actually (atleast in some cases) communicate what we want in a micro prop. Thanks man! no no, I will 100% refer you when I get that out cause your channel is a gold mine of information fam! our whoop community is lucky to have you doing these tests and I will also try some of your recommendations (even bought a few after watching your vid XD) Whoop whoop!!

@butterflyfpv 16 дней назад

@@sticky_ricebowl Yes you are right! More competition for companies. So that they are more motivated to deliver the best products. Nice to hear that you also ordered props to test! 😃I think ultimately you can't avoid testing if you want to find the best one for you. I'm definitely very happy that I found low pitch props for my racing builds with high kv motors..

@TorontoFPV 22 дня назад

Great video! More education is always enjoyable!

@butterflyfpv 21 день назад

Yes, absolutely... I'm happy that I'm now at the point where I've tested everything and can pass on my knowledge with a clear conscience🥳

@Tokyo_Dom 7 дней назад

I'm very surprised you found those 4 blade propellers to be the best. Every time i have tested 3 vs 4 blades, all i noticed was 30s lower flight times. And that was consistent for 31, 40, 2 inch. Its easy to see why when you turn the current draw on the OSD, you can see it drawing an amp more on quad blades.

@butterflyfpv 6 дней назад

Yes, it is true (usually) that 3-blade propellers result in longer flight times than 4-blade propellers. But with whoops, throttle control is very important to me (hence low pitch props) and also flight stability. And with 4 blades it is simply better for my slightly heavier whoops (with 1002 and 8028/803 Motors or 802 27k Motors with 12A Board, all those Whoops are over 24g dry weight). The more lightweight (about 22g dry) 75mm Whoops can definitely be flown with the low pitch HQ prop 3-blade 40mm. But unfortunately this prop isn't quite as good for heavier whoops. I hope there will be another low pitch 40mm 3-Blade prop on the market at some point.. Hope this helps..

Ok I try!👍

@dmitryg.8298 21 день назад

Hi! Use you drillbits for holes in propellers? When they very tight for shaft. For example 1mm shaft, what drillbit you recomend? 0.95 , 0.99 , 0.90 ...?

@butterflyfpv 21 день назад

Very very good question! Yes exactly! I use the prop re-drilling-dental-floss technique..Because I change props quite often with all my testing.. And because the prop holes or the motor shafts are (unfortunately) often inaccurate, I drill out the props with a 1mm / 1.5mm pcb drills (sometimes from both sides, and sometimes three times) and then mount the props with a small piece of dental floss in the prop hole. Sometimes I lose a prop in a hard crash, and after the flight I have to check whether all the props are still down on the motor bell, but I don't care.. I also tried 0.95mm and 1.45mm drills, but that didn't work because the drills didn't remove enough material. Maybe 0.98mm/1.48mm would work, but so far I haven't found any such drills. For 1mm I would recommend 0.98mm if you can find one. And otherwise 1mm and either drill in just once (without pulling) so that you only remove a little material or then work with dental floss like I did.
