Turnigy RotoMax 150cc Size Brushless Outrunner Motor

Turnigy RotoMax 150cc Size Brushless Outrunner Motor
Turnigy RotoMax 150cc Size Brushless Outrunner Motor

Upgrade your 150cc size gas engine model with the Turnigy RotoMax 150cc Brushless outrunner motor. This motor will provide clean and efficient power for your large scale aircraft without the mess and hassle of fuel.

When combined with a 14s Lipoly battery and a 250Amp ESC the RotoMax motor will supply punchy, responsive power that only an electric setup can provide.

This motor is specifically suited for carbon fiber & wooden propellers and features an IC style 6 bolt hole design. The shaft has also been tapped to suit a 5mm bolt to make fitting a spinner of your choice easy.

What's the smallest prop I can use on this and get 100 pounds of thrust. (Using the highest lipo power this motor can handle)

where do I get a battery for this beast?

Just get two 7s lipos and run them in series unless you want to pay more for a 14s lipo and pay more for a power supply and pay more for a charger.

You made a proposal for the engine at 359€* I can not put it in my basquet

Here's a video of my hang glider flying with 2 of these motors on a 40AH 14S Li-Po pack.

I wanna make a quadcopter that can lift around 100 kg. Will 4 of these be enough ? Did this guy used these motors ? https://www.youtube.com/watch?v=Bfa9HrieUyQ Please

let me know anyone !

hahahaha I studied that video and that is what brought me to this page also :-) they are tall, have a silver can and are otherwise black thats all I can tell. The batteries on that video looked very small though.

Also he used 8

In an efficient design like the DJI Phantom 3 which can lift 1 lb with 62.88 watts, you only need a combined 6,288 watts to lift 100 lbs of flying weight. That means each of the four motors only need to be 1,572 watts. Efficiency is in a quadcopter is mainly determined by the rotor size (area) to weight ratio. The bigger the rotor, the higher the efficiency.

Thanks for replying ! But one thing , when you double the size it doesn't that mean that you need twice the power. For example if the octocopter and the person will weight 400 pounds , that doesn't mean that you will only need 25152 watts of power. I think you will need allot more , I read allot of articles and they that I will need between 50000 and 60000 watts of power. And of course the propellers and efficiency of the motors and the design will also make impact on the flight. So I think that I need atleast 8 of these motors.

You don't get double efficiency with double the diameter rotor size. You have to raise the diameter increase to the 2/3 power to calculate the increase in lift and you need roughly 3 times the diameter to double the efficiency but you still won't get double the payload because you have to increase the weight of the rotors substantially. You're also gearing down substantially and running a much slower RPM, but the benefit is that it is a quieter and safer rotor at the same lift capacity.

I too have wondered about how the power scales up from a model to a full size aircraft. An approximation of the physical rules can be understood by comparing actual aircraft. The DJI Phantom can lift 1lb maximum for 62 watts while an R22 helicopter can lift 400lb maximum using 95,000 watts. If you could scale the watts/lb directly the R22 should be able to lift around 1500lb. This is clearly not true so some non-linear physics must be at work, probably difficult to fully understand. But if you want to build an aircraft that can lift a given load, one way for a laymen to determine requirements for his design is to compare another working design that is similar. In the case a 100-kg capable rotary lift (heli or multi-rotor) machine the one man Mosquito or Mini-500 are good choices to use for ball-parking. They use approx 45,000 watts which would be 4.5 of these motors. Taking efficiency difference between a heli and a multi rotor would require a little more power so a hex using these motors might have a good chance of working if the output power of the RotoMax150 is not exaggerated too much.

Thankyou for replying! Yes I'm thinking to make a octocopter with 8 of these. Only thing is the frame is pretty heavy but I think it will work . Only thing left is the money haha

Great Motor for using in my Paramotor, now i use it for driving with my Bob in the Snow :-D with 30x8 Wood Prop he generates 34kg of Thrust! Battery is a 22000mAh Tatto Milticopter Battery 12s. I think this is the best Motor for this price!
