Antenna launcher multicopter

Hi Folks,

What is your budget for this multicopter build?

Perhaps $600

What type of multicopter would you like to build?

Not sure. Probably a Quadcopter?

What is the purpose of this multirotor build?

I would like to build a fairly powerful but basic multicopter capable of lifting a roll of fishing line over a big tree (100 to 200ft high) and dropping it on the other side. The idea being to use the fishing line to haul up a stronger cord for an antenna wire.

Shouldn't need a particularly long time aloft, as I imagine that each task would be completed fairly quickly.

I expect a roll of fishing line (plus release servo) would weight about the same as a small camera.

What type of build will this be?

Not sure, either buy a complete kit, or source the various components and integrate them. eg would need to buy servos, controller, RX, TX, motors, batteries, chassis, etc. Can make wiring looms, etc.

What is your experience piloting RC multicopters? What about single rotor/RC planes/other RC hobbies?

As a boy I built many control-line models, and I still build Ham Radio gear. Am a retired Electronics Engineer, so have a good idea of soldering, building, programming, etc. Have a well equipped electronics workshop, test equipment, etc.

What country do you live in, and do you have any additional shipping/sourcing requirements?

Australia. No problems getting bits and pieces.

Thanks for any help/suggestions.

Quick but important question: is that $600AUD or $600USD? Big difference in value

Either really. Need basic information to be able to make a choice.

Could you get a recurve bow? They set you back much less (and learning to use them is hella fun!).

Those arrows are used to shoot light wire over things all the time, and then you can pull over whatever stronger line and wire you need.

Actually I do have a recurve bow. I had tried various other things (catapult, etc), and found the bow is excellent for small trees, but I'm unable to get high enough in the big ones. Still trying though.

Hmm. Whatever you decide on, much success in your projects! :)

While I am thinking about heavier draw weight for a bow I'm also partial to a mulicopter solution =P

I think a standard 450 quadcopter would work fine as the base platform, but I'm not entirely sure as to how the release mechanism would work. You could probably create a small compartment and have the release side be supported by a servo arm that can quickly rotate out of the way, resulting in the release of the roll.

Here is a part list for a 450 quadcopter: https://docs.google.com/spreadsheets/d/1KSYgdkicW6PCUXI501CeqHPDkm-c3mJbPhhf193l72s

Possible complete list:

Frame: Diatone Q450 V3

Motors/ESCs: Emax 980KV Motor/ESC combo

Propellers: Gemfan 1045

Flight controller: CC3D, CC3D Revolution, or SP F3 clone

Battery: ZOP Power 11.1V 4200mAh

Transmitter/receiver: Flysky FSi6 or Radiolink AT9

Thanks very much! That gives me some useful reading to get started.
