I am a relative noob to the RC world, but lately I have a reason to dive in head first...
I have a small company that designs & builds various electrical / alt power gear, much of it oriented around HAM radio and portable / emergency power & communications.
We have been making progress on an R&D project that just won't die... we keep getting closer to something that might work.
The goal of the project:
A small, collapsible flying platform that can lift a communications antenna about 30' off of the ground and hold it fairly steady for anywhere from a few minutes to a few hours.
The antenna is a flexible whip, about 20" long and weighing 34 grams.
Power for the system comes from a DC source on the ground.
Control of the system is limited to throttle only (no transceiver!).
Weight of the tether (DC power, signal for throttle, and antenna feedline) at max (30') height is 500 - 700 grams.
Weight of the air frame (motors,chassis, flight control, etc. is about 300 grams.
Currently building around Black Widow 2204 motors (with ESC built in).
Using Naze32 rev5 or openpilot mini CC3D FC with 5030 props.
Primary construction of chassis is 3D printed ABS.
A few questions:
What is a good way to control motor speed... use a servo tester as throttle? A PWM speed controller? Remember this control is on the ground, hard wired up to the platform.
Any thoughts on the Naze being able to maintain level hover despite wind or movement of the operator on the ground? We are not running a GPS and don't want to.
Am I likely to need custom FC software?
Thanks in advance for your thoughts!
