Of course that depends on what performance you want, which you did not state.
what power set up will i need for the multiplex easycub that i want to use for AP.
thank you for your reply.
I have already stated that the cub will be used for AP, i.e. aerial photography.
So, is a 2 minute climb to 400 feet adequate? Or do you want to hit 1000 feet in 20 seconds? What performance level do you want? AP is an application that tells me NOTHING about the performance level you require.
i have gone thru your writings and i have to complement you, that my knowledge of electrics has been phenominally enhanced , thanks to you again.
now my confusion is about the amperage, voltage, wattage kv, that are mentioned or not mentioned on the specification by the company. then what is the way out. see the links below.
here the is Himax 2816-0890 Brushless Motor, where the dimension is 28 x 33, then why 2816?
I am not going to do this for you. That link goes to the Multiplex site. The specs say this is a 200 watt set-up. So, what will the combined weight of the plane and the equipment be? I want YOU to do the math. Note that there are 28 grams to an ounce and 16 ounces to a pound.
Watts/weight = watts/pound
://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=7992&Product_Name=Turnigy2836_brushless_Outrunner_1200k v. we know the voltage, where's the current mentioned? what do we do? can we rely on the vendors word? what if there's a typographic error?
Well, if you doubt what the vendor posted, then you can buy the motor and test it with a watt meter. Or you can read all the posts provided by users of that motor. There are a lot of them. Have you read them? The information is right there at the link you posted.
Here the Rated Power: 470w is mentioned and in the configuration table: Power(W) 345 is written. How does a novice like me understand.
If you can explain this, it would benifit many.
Again, the owners of that motor have posted the configurations they have used.
If you go back and read the article, you will recall that a motor does not automatically produce a certain amount of power, it depends on the voltage of the battery and the size of the propeller.
If the manufacturer does not post enough information for your needs, and you don't trust the information posted by users, I suggest you go to another motor.
Himax posts a LOT of information about their motors. Their site can be found at:
If you go back to the first post and loo a these two articles. One of the resources mentioned is motorcalc. Tell it the motor and it will recommend prop, esc an battery combinations. THAT is the easiest way for a novice to proceed.
3 ............Sizing Power Systems
4.............Props vs. Amps
I hope that helps.
