@robert It really depends on the manufacturer - normally a larger diameter means more internals, which can create more thrust. The “kv” rating is a measure of rotations per voltage, but not thrust.
hello sir! I want to add a gripper on a quadcopter to lift at least 500g. would you please advise me what quadcopter should I use and which gripper kit ? and is it possible to control the gripper from an application or something ?
@suzan We only carry one quadcopter which has mounting for a gripper: http://ow.ly/4npvmP The underside has mounting holes for the Litle Grip Kit: http://ow.ly/4npvwW (you need a Hitec 422 servo as well as some mounting screws / nuts). You can control the gripper directly from one of your RC remote control’s spare channels (connect the servo directly to the RC receiver).
hello sir, i want to calculate specifcations propellers for a given speed. that is, if I want to have a given lift force, how to fix the propellers that allow for this value of force? knowing that we have not the pitch of the propeller, Thanks
how to avoid red dot indication on propeller in fixed wing uavs?
@Denniz Dcosta, What exactly do you try to avoid ? We do not understand the “Red Dot Indication”
I made some upgrades in my rc helicopter. Thats why it’s weight is almost reached to 10 kg. The old motor is not working. So which motor can handle and fly with 10 kg weight . Please help…
@sujit, you need to determine the thrust needed to carry all the weight of your helicopter. Some brand provide ready made thrust sheets that you can use to choose your motor, it will give you information on the thrust in relation to the propeller and battery. There is a nice software called eCalc that can help as well.
i m an mechanical engineer of 1st year…i want to make a quadcopter which can lift about a kg but i dnt know how to make it moveable in different directions. Can you help me on this
@Tarn Moving in different directions is fundamental to multi-rotors. If you’re planning to create a custom multirotor, simply read through this tutorial series to figure out how a flight controller and RC system allow you to control its motion.
very nice calculations of drone
Sir
I am planning to build a quadcopter which can lift a playload of about 2kg . I am planning to make it as an autopilot which is GPS enabled.
My main intention is to make use of this drone in delivering small stuffs around 3km radius. It should have a flight time not less than 25 minutes.
Is it possible? Can you tell me what are the requirements? Please help me out sir. I have been behind this for months!
@Shimon It is certainly possible, but it’s a custom project and you will have to learn a lot about how to make a drone, as well as long-range communication.
Thank You sir,
Can you please suggest me the following :
- The battery capacity (mAh)
- The motor with its rpm
- The mean or method of long range communication
@Shimon Battery capacity is covered in this article, as is motor RPM. Long-range communication is covered here: https://www.robotshop.com/blog/en/how-to-make-a-drone-uav-lesson-7-fpv-long-range-17518
can you suggest me a set of motor and prophelors have thurst of 45kg.
@sahil We assume you are building a quadcopter? There are many motors which can provide ~1.1Kg of force, for example: https://www.robotshop.com/en/t-motor-navigator-mn3510-360kv-brushless-motor.html?product-code=RB-Tmo-46 with a 15 x 5 propeller will general 1.18Kg of lift at 65% throttle.
Hi, I need a little help as I’m stuck. I bought 1400kV motors and I’m using 10*4.5 props. I’m having trouble flying my drone.kindly suggest me different props coz someone suggested me to change the motors, but I cannot since I’ve invested a lot, so the only option is to tweak the prop size. Please, help me
@Shubham pareek You’ll need to provide more explanation regarding the “trouble”. If the motors are too weak to lift it, then you either need to take off quite a bit of weight (somehow), or use more powerful motors + props. The prop size can be increased up to a certain diameter (see the motor details / specs to get an idea of the max suggested prop diameter). You should be able to cut down on weight somehow - even if it means drilling holes (which do not affect the structural integrity).
