    so there are cw props and you say the ccw props are made for pusher planes, why cant you just reverse your motor and use a normal cw prop on a pusher type plane?

  • @propfella
    @propfella 7 лет назад

    It wasn't long ago that newbies or youngsters believed a bigger prop was better. I lost count of guys asking what was the longest prop a quadcopter could handle. It seemed a quad with small props wasn't "cool". No amount of advice regarding efficiency etc. could shake them. Such talk was old people's talk, in the end I gave up trying and told them to use 11 inch props as long as they were OK with them hitting the prop on the next motor. They were actually buying quadcopters according to the size of the props. I'm no longer in the business so I have to wonder if it's still uncool to have small props. Or have I got it wrong by buying my props according to motor specs?

    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.

    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

      @alasdair4161 6 лет назад

      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..

      It was a back light for my dx6i which told them i had installed one before and had no problems.
      Got email this morning saying its been packed and awaiting to be shipped
      I must admit they have improved alot
      I only buy from them because they have warehouse in my country (UK) so they shipping don't take as long.

  • @upplsuckimcool16
    @upplsuckimcool16 5 лет назад

    PLEASE ANYONE HELP!!!
    Ok so the second number means how far the propeller will move through the air after each rotation......... However, when I look up propellers I see one of them has the second number 24... so it should make that prop move 2.4 inches through the with each rotation..... Then I look at another prop where the second number is 52, which should make the prop move 5.2 inches through the air with each rotation.
    The thing that MAKES NO SENSE AT ALL is the that prop with the second number being 24 has FAR FAR FAR more pitch on each blade than the one with 52 being the second number. How does this make any sense at all!?
    This is SO frustrating I cannot reconcile this AT ALL.... I feel like there is some information that I'm using that is wrong. What do I have wrong!?

  • @discovolante6624
    @discovolante6624 7 лет назад +3

    1:40, pretty sure the prop needs to face forwards if its on a normal plane or a pusher plane, i use CW props on my pusher plane and it works fine and you can use CCW props on either type of plane, just reverse your motor to suit, you need to explain what your talking about, not just say it spins the other way cos it goes on the back because thats just flat out wrong

    • @Kincentc
      @Kincentc 7 лет назад +1

      .... no no no. this is just wrong. propellers have a leading edge and a trailing edge. you CAN reverse your motor and make a standard prop(ccw) do what a pusher prop(cw) is designed for, but its not efficient because the standard prop is indeed running backwards with the trailing edge out front instead of the leading edge.
      then entire point of there being two types of propellers is for you to use to proper one for the proper scenario. please do not go around encouraging people to use the wrong prop for the wrong job. running a prop trailing edge first is a good way to cause damage to your plane, propeller, or yourself

    • @discovolante6624
      @discovolante6624 7 лет назад +3

      yes i know the leading edge always needs to spin the correct way that was my point, you always need to have the propeller facing forwards (the side you see the size and pitch written on most props) my point is you can use a ccw prop if you reverse your motor so the leading edge is spinning the correct way while the front of the prop is facing forwards weather its on the front or rear of the plane. the reason for my comment in the 1st place is why did flight test mention the ccw prop and not go into any detail?

    • @mark675

  • @fulg
    @fulg 13 лет назад +1

    @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.

      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.

    • @howlingwolven
      @howlingwolven 9 лет назад

      +Guilherme Alves It makes no real difference except for multicopters, where some of the props turn backwards. That said, most tractor aircraft, where the prop is in front of the motor and the whole shebang pulls the aircraft, have props that spin clockwise when seen from behind.
      If your airframe has thrust angle built in (some do some don't), then you should stick with the prop for that angle, which is usually (NOT ALWAYS) clockwise. If you have no thrust angle built in, then feel free to install a counterclockwise prop - if it spins backwards, flip any two motor-ESC leads.

    One thing you did not say, what the three wires on the brushless motor are ? positive- negative and the third ? how to hook to ESC, if both motor/esc have no color match on the wires? I see many do "not" match color of wires.
    Weight have anything to do with picking a motor? think that would be first step in picking a motor weight of the plane with everything.
    HOW MUCH WEIGHT CAN 950 KV MOTOR LIFT? can we see a video on this test maybe with a quad copter would be fun to see.
    Do we need to take apart and clean motors inside if you fly at dirt flying parks? best way blow with air is only way?
    how long will brushless motor last, what will go on it? with brushless the bearings wear out first?
    Hobby store offer replacements which companies do have bearings for the motors? do they make you buy new motor. Found best to have spare parts on hand. I learned make sure you can get them before you buy any rc craft even replacement screws hard to get most do not offer them, just try finding screws for v262 quad copter... Best build your self that way you know where you got the parts, and screws if need same parts again.

    how would i attach a prop to a traxxas rustler rc brushless electric motor, that was never meant to have a plane prop attached to it? i am trying to make a airboat that will have lots of torque and high end speed. i am gonna be using a 5000 mah venom battery

    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 ;)

    ...so much talk, so little content! You should be forced to watch your own videos!
    Obviously this is directed to beginners, so discuss what it is they need to know before you make the video, and stick to that, rather than nearly useless discussion.
    Having watched several of your videos, I am disappointed.

  • @skidz8426

    so something I don't understand. if you have a 8x6 prop and a 10x6 prop I guess why would you go with the bigger prop? if your going to get the same travel out of both the 10x6 prop will draw more power plus more likely to break. which I guess leads to the next question why not go with a fast kv motor smaller prop. so if you have a 1000kv motor with a 8x6 prop and a 2000kv motor with a 4x3 your getting the same travel per min. the only reason I can see with going with a bigger motor is for weight balance right now. I suppose I might not understand yeah probably lol

    @flitetest The forces involved are the exact same though and if the inner spacer / ring or whatever you'd call that plastic thingyfoo fits correctly, you won't notice anything. It's like changing the position of a washer to clamp a prop properly, but still keep it between two nuts.
    In other words, the influence is totally and extremely negligible. ;-)

  • @PHeMoX
    @PHeMoX 13 лет назад

    @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?

  • @Bobster986

    I bought some cheap props from a seller on eBay in China last week for my DJI Phantom. I broke my original props that came with it and they are expensive to replace. When I received them they looked the same but were thinner and the tips of the propellers were slightly bent downward. Are these safe to fly my $1200.00 quad with? They didn't seem to preform very well when I tried them, it drifted a lot. Should I just fork up another $40.00 for original DJI props, or can you recommend some other solution? I like your show and thanks!

      john hill your right i realize this is two months old but inferior props will snap much easier and will flex during high rpm situations, when your flying high you don't want the prop to break.

      I have no idea... but it might be r for reverse. Josh mentioned that you would want a reversed prop if you were running engines on a plane so that it wouldn't torque to one side

    Building my 1st airplane fm scratch and dont kno how to get the prop on the Park 450 BL motor cuz ther r NO instructions? it has a funny looken collet-spinner thingy? AND the diameter of the motor shaft is BIGGER than the hole in my 10x7 prop? this is a GREAT video and starts wit 100 different props and how to pick the right one? well i think i gots the right one (?) but cnat evn get it on the airplane! i guess beginners r jst supose to B able to figure it out,,, kinda comical in a way :)

  • @PHeMoX
    @PHeMoX 13 лет назад

    @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.
