I didn’t know they even had this good quality camera’s this good back them, not to mention mics

@tjtg Pusher props are good for screw collets. Otherwise you chance them loosening when you reverse your motor.

Love the early days of flitetest. Josh Scott and Josh Bixler was a good mix. Should get some of the past crew back on the channel every now and then.

@fulg Actually Ben, using a pusher on a rear mount will keep the collet from loosening.

Love rewatching flite tips!😜

Just the tips?

This is one of the best vids and helps understand prop sizes.

Finally someone who explains this to me! Thank you!

Another great video guys! Keep up the fantastic work and continued success! Have a great day and happy flying friends.

Great video guys! Cant wait for the next one.

Absolutely love the "mustache on it's rear"...love it all guys. Thank you.

Pretty good overview for a short episode, nice work!

enjoy watching these videos, I would like to see a segment on finding kv rating and finding the amp rating to match also the esc

This was so helpful. now i know what prop to put on my plane

I learnt a few things in thie episode! Nicely done! :D

@deeringdeluxe I know, that's what I'm trying to say ;) Props have a direction (CCW or CW), you have to mount them correctly (either forwards or backwards based on the motor location) to make sure the numbers on the prop are facing towards the direction of flight. Even if the motor is at the back of your plane, it doesn't mean you need a pusher prop, as long as the prop ends up turning the correct way. It will work fine with either prop type, you just pay more for pushers.

With all these new quadcopter props I think it would be a great idea to revisit this for a video. One thing I'm doing is learning to 3d print a propeller for my ww2 plane. It's a great small flier but it can't land or take off cause the factory prop is a huge 2 bladder prop. It does great but I want to play around with different propellers and see if it will work will a 4 bladder propeller.

2 years later.....did you have any success making props? I thought about making a silicone mold of a few props and then just pouring my own from epoxy, but probably too heavy.

So this is what happens when you have a guy in speed and the other one high in the same video.

We need this intro back for the newer videos!!!

See, that's the explanation a noob like me needs! Thanks a lot for your great videos guys! Now please do one on how to actually balance your props :-)

Cool Intro, FliteTest!

@deeringdeluxe It does! I made the mistake flying a Swift 2 with the prop backwards to what it should be and it really feels sluggish in flight. A prop mounted the wrong way will fly,yes but it will totally be less efficient and less thrusty. The motor direction defines whether it will move forward correctly, but you should never fly with a prop mounted backwards if this means the wrong way is pointing forward in flight.Don't forget props are shaped into a curvy surface that works like a paddle.

Nice work again guys :-)

Great informative video. I have a dji phantom version 1 I'm currently using the standard 8043 plastic props. I flying with dual 2800 mah 3s lipos and a gopro hero 3. I'm wondering if I should upgrade my propellers to the carbon fiber 8 inch props due they are more stiffer and I'm carrying a little more weight or continue to fly with the standard props. Let me know whar you think.

Really like the way both of the Josh(es) interact and and dynamics they bring. Very professional channel that kind of reminds me of Myth Busters. The RC industry needs your approach! Another factor to bring to prop choice is the number of cells in the battery - which affects KV choice - and rated Watts of the motor and ESC. Also, ground clearance for the prop, rated RPM of the prop, differences between gas and electric props. I know its a lot but a multi-part series would be good. Great job.

How are u?

@lpbug Use blue loctite

I'm interested with the combat wing's motor mount. Please tell me where did you get that.

Love your channel guys. I'm interested in controlling the noise that the props make. I assume there is some kind of relationship between RPM, prop length, pitch, thrust, and noise. How do you find the right balance between thrust and noise and will quieter props be more efficient? Would love an episode on quiet multi-props. Can a quiet tricopter be made with large props and slower motors with more torque?

Great video, thanks. Is it correct that a larger prop for a slow flyer such as a 3d model is better suited with a less cell lipo but with more mah?

Do they define CW vs. CCW viewing from in front of the plane, or viewing from inside the cockpit of the plane?

what are the differences between props for forward flight/ fixed wing and props for quadcopters?

Hello, how are you? Wonderful details on props. I would like to know that can I switch to single blade prop from a 3 blade prop. I have 1100mm fms typhoon.

very very interesting video.

love this intro and miss it too :(

Hi, I wonder what device that you used to test the thrust load, which the propeller can produce. Could you share more info about that device? Thanks

I REALLY LOVE WATCHING YOUR "FACE" ITS SO MUCH MORE IMPORTANT THEN WHAT WERE TALKING ABOUT! and your trying to start a business?

Ah man! I bought a normal APC 6x4 for my bixler. I didn't know I needed a special propeller. I heard that I just needed the accessories kit for the NTM motors.

Hey guys, love the show, but I want to correct something you said about pusher props. They are ONLY required when you need to compensate for the torque roll of multiple motors on a plane, or a quadcopter. You do NOT need a pusher prop when the motor is mounted behind the plane; you mount the prop backwards (i.e. the numbers towards the motor) and reverse the motor direction, so the prop turns the correct way around. Look at your Swift II, you don't have a pusher prop on it ;) Cheers, Ben.

hmm for multirotors i was wondering if there would be advantages to placing the motors on the bottom of their respective boom, facing downwards instead of up and then flipping the prop. i would think less thrust would be lost due to air current impinging on the boom below it. basically it would probably make a low pressure area right around the boom as air flows around it slowing it's downward speed to move transversely to move around the boom thus reducing the net flow or air velocity in that area and then reducing reaction force on the prop and thrust. i guess the trade off is the suction area ahead of the prop. maybe the boom being in front of the propeller it would cause reduced supply of air to the propeller and have even worse effect and this is why nobody mounts the props on the bottom side of the boom?

"Like a mustach on your rear" LOL you guys really are making cool videos, keep them up!

Nice work guys my q any stable rule for propller size with size and plans whight thank you

You only need a pusher prop on either IC motors or where counter rotating is required. Electric you can always make the motor run either direction

Y'all should do a video choosing the right props for quads

would you guys pls do a video about prop adapters, almost nobody includes an adapter when you buy a motor so it is a headache to look for the proper shaft and prop for the motor. Thank you

I want to which design of prop produces Max. air (just like fan) thrust is to be produced downwards

Can you guys show us how to use the prop balancer? And I was expecting to see some rules of thumb and principles of choosing props, motor Kv, number of lipo cells in series, etc.

Wonderful

@flitetest Good point. I still don't think they are worth the expense for single-motor crafts; use lock-tite on the collet (or a prop saver) and don't spend the extra money for pusher props ;) Cheers, Ben.

Can you please give me a tip on what propeller should I use as a rotor of my rc AVENGERS helicarrier project

are 9*6E propellers the same as 9060 propeller.if not then pls tell me the difference

What propeller i need for Turnigy D2830-11 on 4S? (Tricopter, 1000grams) cant find 8x4 that isnt slowfly. 10x5 is too "heavy" for 4S on those motors.

what is the best prop size I can use on my x alien 550? im using sunnysky v2216 800kv, 5000mah 3s battery, auw 1600g.

Hey, I am a hobbyist can you tell me how do you select the motor for rc aircraft? How much thrust to weight ratio do you choose ?I have built a plane of around 6kg how much thrust is required?

Could you please do a video on prop adapters and how they are used.

Thank you for evolving little Josh through his dumb Josh, special Josh and slow Josh phases. I kinda like the new wise-guy Josh..."rear end mustache" 1:40. I like it. I'm just kidding...great work!

As the guy on the flight line that got elected to straddle the new 1200 horsepower turbine to adjust the variable pitch prop governor, I can tell you that all fixed pitch propellers have a narrow efficiency window to operate with. Airspeed and pitch is everything. If you change the pitch and/or diameter, yes, it's possible to go faster - within limits. Balance the tradeoffs in your choice. A high pitch propeller gives you a long roll on takeoff. A low airspeed, heavy biting high pitch prop will likely never exceed 60MPH. Propeller formulas always include airspeed because of it. For any given propeller, engine and airframe combination, there is a speed at which the propeller noise is at a minimum. A noisy prop (too fast, too slow, bad wind angle, turbulence, etc.) is eating your power wholesale with a reduced return in thrust by comparison. A propeller blade operating in the wake turbulence of another propeller blade is definitely at the wrong airspeed. Drone props are designed for 0 airspeed. Insufficient airflow across jet engine blades and the compressor will stall sometimes violently and wreck the engine. The length of the prop blade is directly proportional to the work required to keep it balanced and the amount of grass your cutting on taxi. In any case, vibration from any source is bad and noisy. There is no such thing as no damage from any prop strike at max rpm. Based on what's usually available to most people, it's very likely that you have a choice of three props for your given combination that will change performance; and three more if the blade count changes. Choose carefully and you maximize flight time. A goal nobody argues with ;)

Thanks

Hi, what is right prop for a avistar elite 46 usin an engine super tigre 7.5cc ?

I've a 1000KV brushless motor so what should be the propeller size, which will give the most speed and how much it will effect my F117 RC plane??

Hi @flitetest - where did you source those miniatures propellers from? I would love to have them. Any link to buy them all?

this was my question that i found no where else that "is the pusher propeller different from tractor one". so basically if you rotate the tractor propeller the other way than for which it is built, u get a pusher propeller, right?

what would be a good prop for 1000kv dc motor???

Geometric pitch is the design of the prop and the amount it should move forward in a perfect world. Effective pitch is the amount of forward movement you actually get.

I have heard that when two propellers are installed in a straight line then if one rotates clockwise and the other counter clockwise it produces more thrust.is it true.

Just curious if this is an exact science or rather hit or miss regarding choosing engine size (and appropriate prop dimensions) for max performance vs max flight time for planes and copters. Larger motors turning larger props at slower rpm use less power than smaller, high revving motors with smaller props, or is it the other way round....?

Great video how do you know from a push prop pull prop and could you tell me what a good push prop for a 2400 kv/ and a 2200 kv motor pllleeeeeease want speed.

Everyone's beginning to get sick of HobbyKing and their outrageous shipping costs. Seems like no matter where in the world you're located, HobbyKing will find a way to do you in, essentially forcing us to purchase larger quantities in the hopes that costs subside. They are also very sneaky, not revealing estimated shipping charges, then expect us to register, then enter banking details only to eventually find that the shipping costs are generally far to high. HobbyKing, it's time you get your ducks in a row... and your props balanced! =P

The best thing I ever did for the sustained enjoyment of this hobby was to ditch all connections to Hobbyking. Unsubscribe... close account... detatch from email lists. So now shopping elsewhere, the options have all improved, the prices are cheaper, the shipping is no longer sneakily increased with grossly over estimated weights, There is no more angst and pain when it comes to warranty claims with a stupid ticket system, the quality has improved enormously, and I can now buy more stuff.. Really Hobbyking are a textbook case in how to ruin a business through bad ethics. They will always have their place with an endless drizzle of temporary customers, but the counterpoint is what they could have been.. they literally hurl their customers at their opposition rather than being the biggest most successful business in the world.. Treating your customers with a broad stroke of contempt and treating them like idiots will always have the same outcome in the long run..

I have designed and built a 44in wing span b17, i need help on choosing props and motors. Its made out of foam board in true flite test fashion

I have a suggestion for all of you that are confused about props. Order a range of props and then double each order just in case you like one or more. Get your fuselage on the bench and your power meter, and after carefully balancing each of your examples, run it thru the paces. That will give you a more than a rough idea as to the max diameter and bite.Make note of power consumption for each set-up and simply deduce "Dear Watson" ...and then take no more than three props to the field to test.

Do you know where I can get a 7x4 clockwise propeller? I've been looking all over the internet.

Hi I am having a sbach 342 Balsa wood aircraft but I am confused in choosing propeller for that .. pls help me choose the wright propellee

@deeringdeluxe There's really no need to respond to me like that, I even stated the motor direction defines which way the thrust will be. But regardless of that a prop really should always face the correct side, as that's when it will work best (you can lose up to 50% thrust if its mounted backwards). A prop that's on a pusher plane will function like a pusher prop, even though you'll have to put it on backwards compared to the motor itself. So what exactly is your point?

You would be better off with a folding prop if you are using a tractor style motor. By folding out of the way the drag is reduced and your plane will have a better glide ratio.
