Software for the original Arducopter 1 ?

Started this discussion. Last reply by Mirko Denecke Apr 7, 2015. 1 Reply

Hello I was a way from the Arducopter scene for a lengthty period. I still kept the Arducopter 1 with its brittle plastic landing gear and original hardware that I would want to see in the air again.…Continue

I pulled out the Arducopter for renewed trainings yesterday. Lots of snow here and below freezing temp.  Still too unskilled and with some wind I lost orientation of direction and steered the wrong…Continue

Can some one re-assess the choice of adding those"glow" effect menu entries on the site. Things look quite bleak now in navigating DIY DRONESand is not a good improvement in my opinion. I begin to…Continue

I read this post in a another forum where a guy claims 50Hz is insufficient PWM cycle for accomplishing quadcopter stability. Is there a truth in this ?  What is the cycle of the ArduPilot PWM…Continue

Please tell us a bit about your UAV interest
I remember watching the older guys fly RC models in summers back in the 70´s and I always wanted to get into it. My only experience back then was within 5 seconds of first flight crashing my control line stunt model that had an all too powerful O.S glow engine. Here we are 35 years later.

I recently picked up realizing this teenage dream to master RC flight control. I got some Phoenix simulator mileage now. I´ve quickly ended up with six RC planes in different states of assembly and associated field gear, without even having flown any of them yet. I own an AR.Drone with 30 seconds flight time so far, I will explore mobile phone interaction with UAV´s as time comes :) UAV is cool because it gives a great hands-on insight into accomplishing stabilizing features not present in traditional wing based RC models.
