Here’s a flight from Donald Qualls.
I attended another fun fly with CAFFA (Carolina Area Free Flight Association) today in Raeford, NC, and after a few minor adjustments and one significant tweak, got a very good flight with my Squirrel.
This is still a stock squirrel, built according to the free plans, except that I removed the toothpick rear motor hook and its brace, and replaced them with a wire hook that will retain the motor after power runs out, thus allowing the Squirrel to glide (it doesn’t glide well, but it doesn’t just dive for the ground). With a fresh loop of 1/8″ FAI Tan Super Sport a couple inches longer than the hook spacing, lubed and stretch wound to 1200 turns, I was able to record a flight of one minute, fourteen seconds (1:14). I expect I’ll be able to better this in the future, with a somewhat longer motor (which will eliminate the loop-and-dance that took the model out of frame for a few seconds, by reducing initial torque a bit) — and this is still a completely stock Squirrel airframe, made with wood stripped from a Hobby Lobby plank and Esaki tissue, and using the original size and type propeller.
