What is the maximum rpm those props can handle?
 dvdt2 45 points
Don't worry about the max rpm of the prop, but worry about the prop that the motor can handle.

dvdt2, what a **** answer. Sanihaus, I wouldn't push these much past 12k as there quite soft. They would handle more before failing, but they de-pitch at any higher loads. The carbon fibre versions are the same diameter, pitch and airfoil, and these would handle considerably more RPM. Not much more expensive either.

12k?? is use this props on 1000kv motors with a 3s battery without any probem

Am looking for this size prop but none of the props listed say what size shaft they will take. My question is are these able to take an 8mm shaft or which props should I be looking at? Any help greatly appreciated.
 sanihaus 55 points
the hole i 6mm in diameter and you will get some spacers for smaller shaft. i do not recommend 8mm shaft, since you have to drill your prop, which makes it weak and unbalanced. i suggest a smaller shaft. i had 8mm shaft an put a new 6mm thread on it. works just fine.

On my tricopter Im using this props but I have some questions I hope you could help me with. The front left motor and tale motor is turning clockwise and the right front motor is turning counter clockwise (this is the tricopter setup with the KK2.0 flight board). I`ve been adviced to use the Prop 11x4.7SF with RH rotation on the tale and two identical "normal" Props 11x4.7SF in the front motors in order to make it fly, but this setup does not work. In order to make it fly I need to use Props 11x4.7SF with RH rotation on the front left and tale and a normal Prop 11x4.7SF on the right front.... So do I do anything wrong by using the last setup? Anyway this is the only props-setup that makes it work, but I was wondering if there was someone else having the same issues? This also seem to be good valued props for newbies but What would be the recommended props for more advance users? Thanks in advance for your answers.

hi , on a tricopter you dont need special props just put regular ones on every motor
 balsam 11 points
george: that absolutely not possible if you want to make a tricopter fly :)
 george 80 points
no thats true on a quadricopter but not on a tricopter man
 george 80 points
just google : prop tricopter and read any forum you will see

With two motors running clockwise and one cc (for a tricopter setup) its impossible to make it fly with 3 similar props. Thats basic physics! Anyway, I have the solution (2 SF with RH rotation and 1 normal prop) but thanks for trying.

I fly my tricopter with 3 of the exact same SF props... Flys like a champ! It doesn't matter which way any of the props are rotating on a tricopter as long as the air pushes down (read: swap two wires if air flows up)

Hey balsam what's basic physics of copter flight according to you .....I don't know anything about your understanding of things like "physics's " which is a big word by the way.....BUT in a quad copter the whole craft uses two sets of props rotating in mutually opposite directions in order to keep the copter stable in the yaw axis...think of yourself twisting an umbrella in your hand when you are in free fall...the torque that you exert in the umbrella to make it spin exerts an equal and opposite torque on your body which will make you spin in the opposite direction of the umbrella...on the ground you barely feel this torque because you are firmly rooted to the ground ...in reality you are exerting a torque on the ground and the ground is doing the same to your body which helps you spin the umbrella without you yourself spinning in the opposite direction.....this is the same principle used on a quad copter to stabilise it in the yaw axis..when two sets of props spin in mutually opposite directions the torque on the quad frame due to each set is cancelled by the other set of props ...this helps you maintain heading while flying ...at the same time this ingenious arrangement of props is also used to initiate desired yaw motion...on a tricopter even if you have all the props spinning in the same direction the whole body will want to spin on the opposite direction due to the same effect as stated above but at the same time the tricopter uses a thrust vectoring tail assembly that compensates for this torque by vectoring the thrust in such a way that the yaw is stabilised without any change in the motor speeds....all said and understood it is perfectly fine to use props spinning in the same direction on a tricopter.....

Thank you Akshat. Very good explained. Much appreciated. And thanks to george and Majestik too. It just makes me confused when the KK2.0 flight board "tricopter setup" ask you to have tale and front left props CW rotation and front right prop in CCW rotation. I guess the setup is there for a reason and that requires different set of props. Anyway I will try as all of you suggested with all props spinning in the same direction. Thanks again for your time and guidence :)

Just received them, good look.
They are actually Gemfan composite Propellers. Very clean finish and for the moment I have to say they look pretty well balanced.

You can't beat the price anywhere. These props work really well with slower rotating motors. I use them on my slow stick and it has plenty of power.
