well, these are relatively thin and lightweight, the curve is not very aggressive, so they fit slow fly purpose quite well. Some even use them in multirotors and reported high efficiency and low noise operation.
But if you really need the slow fly speed, better go for 10x4.5 SF propellers, their pitch is better for that.
Jose if you look close the blade twist is opposite to the normal. The counter rotating is just that! Normally a motor turns clockwise. So these are for when you want a motor to turn counter clock wise! Good Flying.
Jose you need to measure the prop you have. These are 10 x 6. So they a 10 inches long. 6 is the pitch which is OK. You would only be able to use the 3 normal props (not the counter rotate). There are plenty of just normal props listed in HK.
NewToHobbyKing is wrong. Once they fit your plane in terms of diameter and pitch, you'll be able to use them both - you just have to swap 2 wires of the motor to make it rotate in opposite direction.
I've bought the normal and counter-rotating props for my differential thrust-vectoring project, but ended up by using them in normal planes. Works fine!
do you calibrate the Props? do the Props vertical on a horizoltal Axe/Nail/Screw and put some Tape on the side which is lighter. Until all blades weight the same.
Kalibrieren. Den Propeller auf irgend ne horenzontale Achse stecken. Die schwere Seite wird nach unten drehen. Das Ende der obere/leichtere Seite mit Klebeband beschweren bis beide Seiten/flü*gel gleich viel wiegen.
I am wondering, what is the difference between a slow flight blade and ones that isnt? Im new into this hobby and im just curious if its the types of blade sizes or the formation of the blade? thx for help
The slow flight blades are noticeably different in shape and weight. They are much lighter and very flexible. The blades are very thin.
The other blades are much heavier and are quite rigid. The blades will not have any noticeable flex. They are thicker.
Slow flight blades are designed to create significant thrust with lower RPMs but with significant loss of efficiency when pushed to their limits. High performance (or standard) props require a higher rpm rate sometimes, but maintain their pro
Hi, I am very new to the process of fitting props to shafts and need a little guidance. So far I see that I need an adapter to connect to the shaft of my motor. But after that how does the prop actually connect to the adapter? Is it through tightening the adapter down on it or a little hex nut that is also needed? Thanks,
i actualy using this props eith hackerstyle 20-22l so if you take a look to additional stuff which comes with this motor you will find two kind of adapters, i prefer one with m5 thread , prop will tightened with regular hex nut in this case wery strong. Also can be used regular adapter with propsaver, ehich are actually rubber ring
This prop has hole diameter of 3mm. Im using AX 2308N motor so the prop just goes directly on the shaft and tightened it with the provided shaft screw. If you want to use adapter u need to enlarge the hole to maybe M5 and use prop adapter. Avoid adapter with hex nut coz aluminium may not be able to stand over tightened. Use the screw type adapter where u tightened the prop and securing the adapter on the motor at once.
as you have mentioned that propeller hole is of 3mm and as i know motor shaft is also of 3 mm so
in my opinion u must use 4 nuts to fit one propeller
2 nuts will be fitted in the propeller's nut marks.
first you add one nut in the shaft then the propeller with 2 nuts fitted in it and then add the last nut at the top.
Hi, i use the same Props on my Hexacopter i just build and also on other Quads and Tricopters i had build in the past. To see performance please visit my Youube Chanel my Username there is also wolfes1126. I have had never yet 1 of the Props come apart on me in flight and i always have a flyingweight of around 2kg or about 4 Pounds or more. If you find this Information usefull please let me get rewarded. thank you
I just finished my quadcopter on which I installed these helices, they seem flexible, but it can fly with a total load of 4.3kg (load frame) with four engines each consuming 25Amp, but you must balance thoses propellers
I drilled mine to 5mm and there was still enough space, so yes you can drill to 7mm easily, just a suggestion drill gradually meaning start with 3mm then 4mm untill you reach 7mm this way you will not mess the prop alignment and balance
Its possible but you would be better off choosing a prop with a larger diameter shaft hole to begin with. You will have to eat into the hub and it will weaken the structure. Depending on the method chosen to drill the hole you are likely to drift off center and this will make the prop vibrate. These props are also not designed to be spun at high RPM and anything that requires a 7mm shaft sounds like it's got some power behind it they will simply cavitate.
My ones are all may of balance!
They fit perfect on a M4 shaft.
Drilling the hole is possible, but only with rebalancing them of cause. They won´*t break at the center of the prop! Think about the law of physics. The will break at the shaft of the blade in case of giving to much power tgó* them!
The adapter comes with the Turnigy L2215J-900 motor is threaded, drilling the holw may not suitable for this. Maybe, drill the hole on the propeller and tap it to fit the adapter of the motor. Any one has any idea? Thanks.
Hi, I've bought these props but they cannot be used on my axi 2212/20 'cause the motor's male hexagone is much smaller than the prop female hexagone... wondering if some kind of adapter is available...
The prop doesn't fit the motor directly, on the 2212/20... the motor is an outrunner, and you fix to it a plastic adapter with 3 screws. The adapter has a hex protuberance the prop fits in. Now, the prop's hex hole is too big. Does an adapter to match prop and motor exist on Hobby King?
Yes it will not fit on the main shaft because it is so small, but if you install the adapter that comes with the motor accessories then it will fit perfectly, all you will need probably is some round files.
I tried these with my Quadrucopter with FY90Q stabilizer and I think that the quad would be better with lower pitch props so that the there would be less loss of lift from RPM change. 4.7 pitch props seem to be popular choice for Quads (not available at HK), but I tried GWS HD8040 and HD8040R 3 Blade Props instead and less pitch/thrust seems better indeed.
Product id H1011A are standard 10X6 propellers. This product(HCB-10) are 3 units of standard propellers plus 3 units of counter rotating propellers. Very usefull for quadcopters, for example. Same size and quality.
