I got my Kronos flyer in the air today with pretty good results. Here are the build facts:
Kronos flyer with motor extensions, Futaba 8 FG Tx and Rx, Ardupilot APM 2.9.1 w/Blox GPS
Michael at Kronos Robotics designed the frame and sells the frame pieces at his web site: http://www.kronosrobotics.com/multir...er/index.shtml
I flew for about 25 minutes total and found controls to be overly sensitive so I'll start experimenting with the tuning process tomorrow. It required way too much forward pitch and right roll trim. My quick preflight balance job was flawed so I balanced it well tonight and will see how it goes.
The flyer itself was great, it is stock with the exception of a quickly built isolation platform using Sorbothane isolator grommets. Isolation performance was okay but I still need to work on it. All in all I'm happy with my start as a rank beginner...
Motor extensions worked great, about the only thing I'll change is to add legs in lieu of the landing gear. Once it gets tuned up I'll add one of the newer Kronos platforms.
