Enjoy my explorations with a tricopter managed by APM 2.5. Having loiter and return to home for flying FPV is the only way to go! I spent a fair amount of time tuning this summer but if anyone can suggest how to eliminate the slight wobble in forward flight I'd like to know.
The flights are in and around the Central Alaska Range near the eastern edge of Denali National Park (but not in the park). There are clips from one flight near Fairbanks.
The tricopter is a variant of the design from David Windestal (recexplorer.se). My next step is to try some photo mapping and find out how various vibration dampening systems work in sub zero temperatures this winter.
