Hi All,

I am very new to quadcopters, I want to demo one project on small delivery system using drone(Coast matters)

I was researching on multiple options, but i am little confused

Requirement
- Fully Autonomous drone
Give way points and program the wayponts using GPS coordinates/some beacons (using APM 2.6 controller we are able to achieve this)

- Carry weight up to 1KG
Need to carry a box of 1KG for minimum distance may be 50M to 100M

- Fly time is very minimal 5min

  • My question is Should i buy one or build?

  • Which is one is cost effective?

  • Can somebody give some options on buy?

  • For build, What all the motors, propeller, frame and drone type(Quad or Hex) i should use to get that trust to carry 1KG(Drone weight + 1KG)


Thanks in Advance
 
Just did some searching and most any racing drone would work or anything around the size of the bigger DJI. For cost savings you will benefit from building your own assuming you have greater than novice skills at soldering and debugging issues, that said DIY is always a trade off in time investment and learning. The ecalc here https://www.ecalc.ch/ is a good resource to plug in numbers and components and get some idea of expected thrust ratio. I just punched in the numbers for my 'racing' quadcopter and it would be able to handle it no problem, I built it from off the shelf components (from Amazon mostly) and it cost me around $300-400 (depending on if you include transmitter and cheapo fpv gear I bought at first). What I have is missing a GPS module and any sort of sensor for altitude hold (meant to get an FC with built in barometer it would have been $3 more on the $40 purchase but clicked the wrong option). The weight of mine is 1lb 6oz or around 690g, it has a thrust to weight somewhere above 4, so it can lift more than four times what it weighs basically and flight time is about 3-5 mintues when I'm punching the throttle around a field. Can easily go around a few baseball fields in a single battery.

Buddy of mine bought a kopis1 recently as his way of getting into the hobby more seriously and it has been pretty good so far but very small frame so might struggle with places to add extra sensors etc. (3d printer helps a lot with little spacers and connecting parts).

Long story short it just depends on budget, timeline, expectations for building/learning vs just need something to do the job.

Edit redid calc with closer to real numbers for mine. Will try some real world tests next week.
