FireFLY6 DIY 25


Now shipping internationally!

With 25 minutes of average hybrid flight and an included AvA Mapping Key, the DIY 25 package is the best choice for the most discerning aerobotics enthusiasts and those who are looking to apply the FireFLY6 in productive missions. AvA brings a slew of features to the FireFLY6:

Stress-Free Transitions
AvA handles flight mode transitions (from hover to forward flight and vice versa) for you, making the most challenging portion of VTOL flight as simple as a flick of a switch.

AvA brings full VTOL flight control capabilities to a single piece of hardware, the PX4hawk autopilot.  The result is a clean, uncomplicated electronics installation.  No muss, no fuss. 

Safety & Reliability
A single controller architecture means that failure points are minimized.  But if things do go wrong, AvA can step in to save the day.  Return to Launch (RTL mode) is available on demand and as a loss-of-link failsafe, bringing the FireFLY6 safely home for an automated vertical landing.

AvA handles all of the complicated control mixing required to keep the FireFLY6 airborne.  No special radio programming required, any 7+ channel radio system will work.
