FAI-F1D
Free Flight Indoorist
The big 62" model has been hiding in a box for the past 6 months. I finally got it out, built a new smaller wide blade prop, and promptly reeled off a 38+ minute flight at yesterday's Cat 1 indoor contest. This is within 90 seconds of the world record, so it's time to get the paperwork rolling for an FAI contest sanction.
