Motor Choice - 2,5 kg

[Peer Hems]

Dear all,

At the moment i am building my first quadcopter for an art project.
The quad has to hold some stuff which makes a total weight around 2,5 kg.

I have a 600 frame and now i am looking for the right motors and props.
It won't be a racing drone, so the maximum speed isn't that important.

If I am right, I need around 1375 g thrust per motor. (2500 * 2,2 / 4)
I am thinking about using 4S LiPo to reduce the currents and prop size.

Is there somebody who has some experience with this size of quad and this weight?

Thank you in advance.

Hi mate you want a heavy lift pan motor about 350 - 650 kv run on a 4 cell with 15x5.5 props it wont be fast but will lift a house

I think that motors are a little bit over powered right?
It can lift an 18kg hexa and my quad will be around 2500 gram.
Do you know any motor prop combination with factor 4 lower power?

I use these

NTM Prodrive 35-36, 910Kv from Hobby King, excellent quality, and my 450 can lift an additional 3Kg with 11" props... I done think I can fit 12", tho, 10" CF props work very well

Hi mate I used the 1200 kv prodrive what a motor quad is mega fast just heavy motor wish they could make them lighter

 

[Peer Hems]

Thank you AxeGrinder, i think i will try that one. In the specs they advice a 3S, but i prefer 4S for lower currents.
What did you use?

 

[AxeGrinder]

I have used both with no problems. I fitted 30a escs, but if you add 40a, you can lift bigger weights...

 

[Peer Hems]

Okay, I think that i will 30A escs, otherwise i take my motor to the limits..
Normally at hobby king i can find a CW and a CCW motor.
For NTM i can't find two versions, how can i fix this?
It's my first quad, so i am not so experienced with that kind of stuff.

Hi mate just swap any 2 wires this makes motor run the other way and I used a 3 cell on my motors

 

[Peer Hems]

I thought exactly the same, it was just to check

The only time you Need CW and CCW motor are if you use self-locking props or adapters
