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.
