I just became aware of the relationship between the hypetrain race quads' propellers disc radius, disc radius of an electric saw blade, and fidget spinner toy disc radius - Thank you so very much. Outstanding Video - You may not realize it but you helped to save my life.
Best video on props so far, to the point and very easy to understand. Been thinking about trying some tri's and bullnoose, so this really pointed me in the right direction!
Excellent analysis and comparison to car physics. The knowledgeable insights and personal experiences supporting quad dynamics is unrivaled in UA-cam. Great episode Team RR!
Finally! Everything (almost anyways) in one place! This is the type of video that helps promote interest in our hobby from noobs to ace pilots alike. Well done RR.
Yes, I'm late to the party, But a modern race quad will destroy ANY car up to a hundred miles an hour. I've driven an Ariel Atom V8 on track, and it is SAVAGE....But at the end of the day, power to weight wins.
Thanks guys, I am just about to start tuning my quad for the first time and your video is a big help. May have to watch it several more times to under stand more about tuning. Cheers
great vid guys. I went back to a 5x4 from a 5x4.5 and dumped the bull nose all together. flight time is way better now. and both quads handle great. Thanks
Thanks for answering every question (and then some!) I've had about props in 15 minutes. I can now stop sifting through pages upon pages of forum posts and use this as my prop bible. Cheers.
Thanks guys, I've recently changed my HQ 5045bn for 5040 3 blades and I won't go back now! Love these props, really enough speed for me and great response, and a real advantage I discovered is that even if you broke a blade with touching a branch you can still fly and go home and don't have to walk and search the quad....ok....the noise is terrible but the quad still fly.... ;-)
Great info . Thanks Chad and Steele. I flew a gimp-fan tri a while back.... you could hear the blades flexing when you pumped it into a 180° corner and jammed the throttle on to get moving forwards again. I took them off straight away. DAL props all the way for me. 6x4.5 on my robocat with 2206 1900kv... heavier quad and 5x4.5x3 on my qav210 with rs2205 2300kv pocket rocket. Cheers guys!
great descriptions for the different types and handling and uses. technical stuff and bench tests work, but real world applications are good to know too. Thanks!
Brilliant run through guys thanks. Trying to encompass the theory of propeller efficiency in 15mins takes some doing. The helicopter designers have all been through this process. If you equate the type of flying you want to do with a helicopter you will find that machine has the appropriate rotor design already. I.e. Fast, nimble machine, look at a MD500e with 5 short blades. Pro's = Small, high loading disc area, but really biting hard, using those 5 blades to max effect for rapid/agile response. Cons = High fuel consumption/reduced endurance. Slow, cruiser machine, look at Bell jetranger with 2 longer blades. Pro's = Very efficient, larger disc area with lower loading. Low fuel consumption/increased endurance. Cons = Reduced responsiveness, require more clearance from fuselage. The key difference with multirotor blades is their requirement to accelerate and decelerate rapidly to generate the torque for Yaw as well as the asymmetric lift for Roll (all at the same bewildering time!!) The glaring next step would be variable pitch blades which would transform performance. That would be like going from riding a bike with one fixed 3rd gear to a 10 speed racer. fast at accelerating (fine pitch) to high speed blitzer (coarse pitch). BIG problem with that is added complexity and much MUCH more expensive replacement costs when you hit that tree or race pylon etc!! Please do more of these talk through's and you guys should link to your store and sell these blades so we can support your Rotor Riot posts.
Very good video on props. I'm just getting started after flying a Hubsan X4 and a Phantom 4 for a few months, and I really didn't understand the differences between prop sizes, blade count and pitch. Subscribed! I just started flying a Storm SRD250 with 6" props and while I'm still learning how to control it at high speeds, I can really tell that it's a great quad. Hopefully soon, I'll be able to really get the most out of it. Great channel, guys!
+ThatHPI GUY Magic smoke be dammed! In the name of science, full speed! Also, film it, cause everyone likes to see someone else blow up their toys on youtube.
Sweet vid, makes it simple. Would like to see you guys discuss your FPV setups some time - What cams & VTxs you use, how many MW, which antennas you use & why.
Awesome video! It may have been worth while mentioning prop balancing though! It reduces vibrations, and increases efficiency - RPM for those of you curious!
Just want to say thank you for doing these vids. They really helps with my knowledge base and educates me on the different aspects and science behind what each piece does. Also through the videos I have learned what I'm doing wrong like 5 DAL bull nose blades with a Glacier 45C 1300mAh 3S 11.1V LiPo Battery which is too small from what I understand from the video. so time for some different props.
Ok, so I know this is a pretty old video, but there is something you guys got wrong in this video around the 10:00 point when you talked about hang time. You're right that if you're throttled up and pointed downwards, more thrust equals less hang time, but whenever you're throttled down then the speed you fall at is dependent on the prop shape. The air will start to spin the props instead of the motors, assuming you're throttled down. This is what helicopter pilots call autorotating. If you have a high disk space, then more air is hitting your prop as you fall, and more energy is dissipating into rotating the propeller, making your prop act kind of like a parachute. So a higher blade number or a lower pitch will give you more hang time, because it gives a higher disk space. Btw, I absolutely love you guys, I don't mean to insult you or anything, I just know this is something a lot of people forget about. I also know you guys have more experience flying quads than I probably ever will, so I'm perfectly happy to accept that I'm completely wrong if somebody explains it to me. Thank you guys for making these awesome videos and helping people learn and get interested in this hobby, you do a great job, keep it up!
I missed the last run of 5" penta props for my quad. I did however snag up about 20 sets of quadra props. Not only have I noticed a longer run time (battery wise) and without even going into hang time, just lift from an additional blade(s) is very interesting. The motors seem to fair well and may wear out quicker in the long run, but in a yearning and learning sense of aerotecture, I'm on the same page. I like hearing things & thoughts of any age. Communicating my 2¢ or maybe $ of experience and knowledge to the communal forum and walking away a wiser individual or as a enlightened community is always a good feeling at the end of the day. If you want more hang time, fly right side up at low throttle with a high blade count prop. Hang time doesn't necessarily have to be calculated as inverted orientation. The key term difference is lift as opposed to thrust.
Loving your videos guys, thanks for educating us all in this great sport. I'm really curious about your battery habits, how many you have, do you have different batteries for racing and practicing, how many cycles do you normally get, do you break your batteries in.... would love to see a video on this. Keep up the good work!
Great vid guys thanks very useful! I would also like see a vid on PID's and also a talk through on some of the tricks you pull off in the air. Maybe a slo mo with stick controls in view so we can get a feel for what your doing. Cheers
Great video as always guys, the info on props was very informative. One suggestion - 90% of my UA-cam viewing is done on an animation/editing suite at work during lunch breaks or render sessions... the title sequence is quite loud (I have to turn the UA-cam slider below 25%) but the actual segment is very low (I turned my slider to 100%). This goes for a lot of RR clips that are "in studio." Flite Test has a similar issue, but not near as bad. A show suggestion - I'm really just starting out in FPV (but have 2 years experience flying quads) and the "proximity" flying (like a number of StingerSwarm's videos) is more interesting to me than "trick" flying... how about an episode on that? Maybe with some tips? Awesome show, guys!
I would love to see an episode on PID's starting with a stock Cleanflight setup on a Naze32 board and showing how the guys would tune it to get the locked in, crisp, nimble and fast machines that they fly.
Great video!! Very helpful, you are doing a great job. Btw from my personal experience, harder the props more damage to the motor durring a crash. I used sone Gemfan 50x46x2 BN and bent one of my motor shaft...
Cheers guys! I never thought about props wanting to flatten themselves like that. You know what does that noise worse than the gemfan 5030? the gemfan 6030. I always just thought it was vibration.
I love your channel, enjoy every episode. At the moment i am just flying planes, but today is my birthday and well see if i will fly a multirotor in a few day. As a student i have not the highest Budget but I do what i can to enjoy the hobby. You and flitetest help me at this alot. +Rotor Riot ;)
+Tim M-v If budget is a real concern I'd go with DAL 5040 props just because they are pretty much unbreakable. I have yet to do anything but bend them. They are slimmer than other props of the same size so you definitely lose out in overall thrust and stability but you make up for it in being able to pick up your quad, dust it off and keep flying. And as a beginner I don't think you'll notice enough of a different in thrust or stability to make you dislike them. *note I'm still a beginner myself, this is just my experience and i've heard it echo'd by others, some even in this comment thread.
A spinning prop with more blades will likely act more like a parachute, hence why when cornering it feels more locked in rather than drifting around. Up-side-down hang time could possibly be improved regardless of blade direction simply cause the 4 blade is spinning and is providing more resistance from the air thats bumping into it as it falls.. The difference may not be much, but possibly some people are noticing it especially when compared to a 2 blade flying.
I'd be interested to see what you guys would do to compensate for higher altitude. Any chance of you guys doing an episode from a high mountain pass and passing along how it affects your flying and what prop you'd move to, to negate it?
Hey guys, great video. How about doing an episode on fpv and what you need for a fast signal? Also maybe throw in the legality of different fpv frequencies in the US. I can’t find good info on that anywhere! Keep up the good work! Oh, and any chance you guys are going to EAA AirVenture?
Guys thanks for the review very informative, been playing around with different prop sizes 2 blade vs. 3 and 4 blade. You did a great job explaining the differences 5’ tri blades works best for me, now I know why.
LOL, I had to learn tuning my quad on gemfan 5030s ABS. I kept getting frustrated i couldn't get it locked in. Then I got some real props and figured out why.
I'd be interested to hear your opinions on motors. In particular the new range of 18mm and 22mm motors we're seeing from various manufacturers with hign kv values. Cheers guys!
On the weekend I lost a blade on one of 5x4x3 triblade going through an invisible tree branch. I tried to regain control for softer crash and may be took another 2-3 sec before hitting the ground. I burnt out the motor with the missing blade in the process but rest of the frame got away ok. Can pushing the motor with missing blade burn it out? I imagine a missing blade on a tri would be extremely unbalanced and puts a lot of load on the motor??
I just became aware of the relationship between the hypetrain race quads' propellers disc radius, disc radius of an electric saw blade, and fidget spinner toy disc radius - Thank you so very much.
Outstanding Video - You may not realize it but you helped to save my life.
I love it when you elaborate on the technicality and still keep it understandable. Best review of the series for me. Thanks a lot guys!
You guys gotta make update videos like these!!! These type of vids are what get people into the hobby!!
Awesome video. I'm a noobie and you guys just made a lot people's prop choices suddenly make sense to me!
Great episode guys. Very down to earth and full of information.
seriously 1 of the most informational. vidz out.. it answered all my questions. thank guyz.
Best video on props so far, to the point and very easy to understand. Been thinking about trying some tri's and bullnoose, so this really pointed me in the right direction!
Really good video, maybe the best one! Everyone that builds/flies drones should watch this!
Thank you for bringing back the original intro! It's way better. (:
Excellent analysis and comparison to car physics. The knowledgeable insights and personal experiences supporting quad dynamics is unrivaled in UA-cam. Great episode Team RR!
I do prefer 2nd and 3rd gear apexes they are much more manageable than 5th gear apexes in a race track.
Thanks for the prop class. Students totally got it and now want to test props thanks for the class motivation.
Finally! Everything (almost anyways) in one place! This is the type of video that helps promote interest in our hobby from noobs to ace pilots alike. Well done RR.
I think we need an episode where you guys race quads against the top gear guys in cars... make it happen!
Yes!
The old original British trio not the new twats
+Grespino 1 For sure! on the new Amazon one...
The Grand Tour.
Yes, I'm late to the party, But a modern race quad will destroy ANY car up to a hundred miles an hour. I've driven an Ariel Atom V8 on track, and it is SAVAGE....But at the end of the day, power to weight wins.

Thanks for answering every question (and then some!) I've had about props in 15 minutes. I can now stop sifting through pages upon pages of forum posts and use this as my prop bible. Cheers.
I love the car analogy with the gearing. Perfect explanation Chad!
Very comprehensive review of props. Thanks guys.
Thanks for the information guys. As someone new to fpv this helps tons.
Nice work guys, love the analogies Chad and Steele use, as specially the feel

Very informative and one of the best videos you've done.
You guys should go over your process for tuning PID's and rates. I know that would help a lot of newer pilots like myself, great job guys!

You guys are AWESOME! I love all your videos and this one taught me more than I learned in High School. Ha!
great episode, we want more like these!
great work on this episode guys! very informative! the information was presented well.
Thanks for all the advice guys
It has been really helpful
you guys are always informative an fun to watch. keep up the good work. ✌
Great and informative video, learnt a lot about props from this!
I still have a big bag of Gemfan 5x3 props if anybody wants them. They are great for mixing epoxy and stuff like that.
lmao...
I have a tonnnnn myself haha
Nice...
Thank you guys so much for this...as a noob..this has been on my mind for awhile...cheers:)
Thanks very much fellas, it answered a lot of my queries, CHEERS👍🏽
Loving your videos guys, thanks for educating us all in this great sport. I'm really curious about your battery habits, how many you have, do you have different batteries for racing and practicing, how many cycles do you normally get, do you break your batteries in.... would love to see a video on this. Keep up the good work!
Thank you for covering props!
great tuturial guys helps a lot , its a mine field, hq 5x4x3 for me, tried 5x4x4 feels very locked just missing something that the triblades give.
Props to you guys. This video is fantastic!
awwwwww... Steele in 2016... nostalgia hitting
Awesome video. Thx.
Other ideas: matching props to motors, ESCs, batteries.
Quad sizes vs props, motors, ESCs.
More pid tuning vids.
Frame crash strength consideration/what to look for.
Fpv setups.
love your video's. this was great break down on props. really enjoyed it. cheers!
Great video Guys very informative . Keep em coming
A very insightful video guys!
Educational. Thanks for this episode!
Great vid guys. Well explained.
Great vid guys thanks very useful! I would also like see a vid on PID's and also a talk through on some of the tricks you pull off in the air. Maybe a slo mo with stick controls in view so we can get a feel for what your doing. Cheers
very informative guys. can you do an episode on matching prop to motor to esc to battery please
great point
And come full circle with tuning?? Please :)
Nice explanation guys!!! Very useful!!!
I love seeing that basement again! Just like the old times from FliteTest :)
thanks learnt a lot. i was wondering why people choose to use 4' props and this answered my question
Learnt a lot there - thanks. I'm hooked on the speed so I'll not bother with the four blade tris.

+SquirrelyOs Noted :)
great vid.. I've had a lot of luck with the new gemfan 5050 triprops & my 1300mah lipos still have long flight times
I think you guys are great! SUPER helpful! Thanks soo much!
A vid on how you go about Tuning PIDS would help a lot of people out!!!
Thanks for the great video. And I like the quadrotor T-shirt!
Really good episode, cheers guys
great vid guys thanks for the break down.
I also see the force multiplier or electromotive force in the hypetrain race quad motors and the dewalt electric saw blade - Thank you.
I would love to see an episode on PID's starting with a stock Cleanflight setup on a Naze32 board and showing how the guys would tune it to get the locked in, crisp, nimble and fast machines that they fly.
Wow! Great info. Thanks guys!
Great video!! Very helpful, you are doing a great job. Btw from my personal experience, harder the props more damage to the motor durring a crash. I used sone Gemfan 50x46x2 BN and bent one of my motor shaft...
THANKS GUYS !
thanks for clearing that up
Cheers guys!
I never thought about props wanting to flatten themselves like that.
You know what does that noise worse than the gemfan 5030? the gemfan 6030. I always just thought it was vibration.

Hey guys, great video. How about doing an episode on fpv and what you need for a fast signal? Also maybe throw in the legality of different fpv frequencies in the US. I can’t find good info on that anywhere! Keep up the good work! Oh, and any chance you guys are going to EAA AirVenture?
Guys thanks for the review very informative, been playing around with different prop sizes 2 blade vs. 3 and 4 blade. You did a great job explaining the differences 5’ tri blades works best for me, now I know why.
5 inch bi blade high pitch is the best
i have a bugs 2c and i'm going to put a gimbal and landing skid and until now i don't have idea if what i'm going to use if 2 blades or tri blades
I would really like to see your input on PID tuning and input on TPA.
LOL, I had to learn tuning my quad on gemfan 5030s ABS. I kept getting frustrated i couldn't get it locked in. Then I got some real props and figured out why.
Please why is the tip of the propeller flattened?
Or paste a link to the video where you explained it.
Thanks
Really useful! Thank you very much!
I'd be interested to hear your opinions on motors. In particular the new range of 18mm and 22mm motors we're seeing from various manufacturers with hign kv values. Cheers guys!
Well explained guys thanks
Good stuff! Thanks guys!
could you add a comment to the weight of the quad and prop spec. at what weight does a 5x4x3 not sustain well
On the weekend I lost a blade on one of 5x4x3 triblade going through an invisible tree branch. I tried to regain control for softer crash and may be took another 2-3 sec before hitting the ground. I burnt out the motor with the missing blade in the process but rest of the frame got away ok. Can pushing the motor with missing blade burn it out? I imagine a missing blade on a tri would be extremely unbalanced and puts a lot of load on the motor??
Great information! thanks guy! How about some tuning tips?
Are you guys going to talk about hang time and how to practice it, and what you are doing to do it, a how to style vid?
thanks guys very helpful.
Very helpful! Thanks Guys!!
Please do a video on PID settings and tuning
