12 minute Squirrel

I took the new Squirrel to the Gym tonight.  There weren’t many kids, so I had lots of time to fly planes.  I was planning to fly it on a 20″ loop of 1/16″, but the can was empty.  Must have given that motor to one of the kids last week.  I had just enough 1/16″ strip in the bag to make up a 14″ motor.  I wound it to 1,600 turns, just shy of 80%, for a test flight.  It had a serious power stall.  Picked it up, moved the wing back a bit and relaunched, it did 1:02.  Moved the wing back until the CG was at the leading edge and there was still a bit of a power stall, but it made several very nice flights.  I had calculated the motor should be 0.0595″ wide, so I guess I should strip some narrower stuff and try again.
Darcy shows some Squirrels with only one winglet.  I decided to try a wing without winglets.  It makes a beautiful illustration of a spiral dive; an accelerated tightening dive.  I suspect the right winglet is the preferred if you are going to have just one.
