Australian Squirrels with 4″ Propeller

Experimental, Gallery, Sighting

We ship lots of Squirrel kits to Australia but there are a lot of DIYers there.

Keith Harbottle is setting up a High School Camp and he was not able to source the 5″ propeller.

The Squirrel should work fine on a 4″ propeller. The workshop is being deployed this week so we may get some more pictures.

Below are a couple of his experiments. He made a smaller Squirrel to see if it worked better with the 4″ propeller but I think he will find it’s much easier to just make a standard Squirrel then substitute propeller.

I’m curious if those 4″ propellers turn in the opposite direction. 🙂

Bamboo Squirrels

Education, Experimental, Sighting, Testimonial

Professor Francisco Souza (of Uberlândia – MG – Brasil) had the Squirrel as a final exam for first-year Aeronautical Engineering students.

About 30 students used a gym and the winner “Jefferson” made the flight record of 22 seconds with an all balsa Squirrel.

The bamboo Squirrel below did very well too.

“I was impressed by the finesse and performance of his model”. — Francisco Souza, Faculdade de Engenharia Mecânica
