Need to lift a package of 2000 grams (~4.4 pounds)

[Jens Olsson]

I am considering a project including a quadcopter where I want to move a packages weighing 2000g (approx 4.4 pounds). I then want to use a GPS to find the location where the package should be delivered.

I need fly 5000 meters on one charge and I need it to move quite quickly.

Is this at all a reasonable project?, if so:

1) Should I make a quad, hexa or octacopter?
2) What size of batteries would I need?
3) What motors should I use?
4) What size should I make the copter?

Kind regards
Jens

Sorry for the delay in response. I'd definitely say the more props the better in this scenario. Typically bigger payload copters have more than four props, although there are some heavy lift quads I've seen out there. For exact specs, you have one of two options:

1. Find someone who has built something similar to figure out what the power-system and sizing should look like. Crazy enough, I find that it's easier to find build specs on youtube than anywhere since most people list their specs with their videos:

2. Use something like e-calc if you're comfortable with the math/physics behind it. This is a very good tool to figure out how to size everything. I personally don't want to risk too many mistakes, so I usually go the tried and true method and take other people's provden builds and modify them to fit my needs.

There are also some ready to fly heavy payload copters for sale, but they're expensive!

When it comes to GPS, just get a board that supports GPS with waypoints.

3 miles is a bit much, but not impossible like MM said, bigger props and Low KV motors. If you can go for higher voltage that is a plus. Approximately what is your budget?

4 pounds is not too significant. A Hex with 12 inch props would be able to do the lifting plenty easy and may do the flight time.

Use this tool to test out some ideas.
