A week ago we went to test fly again. The plan was to do a series of flight to evaluate the endurance of the helicopter and also do some failsafe testing. It was quite cold and windy (-17C and 10-20km/h):

We had 3 successful flights, including a couple autopilot takeoff and landings. The heli was struggling with the winds aloft though and had trouble hitting the static waypoint locations. At the end of the 3rd flight we discovered that the ductile to brittle transition temperature of the polycarbonate landing gear is around -15C:

Oops…

Not too much damage though, mostly just the landing gear and rotor blades! It did get me a chance to take a look inside the hanger (which is a very convenient thing to have at your UAV field!):

Nice to be out of the cold wind!

It was an interesting day and kind of nice to know that we aren’t the only ones having flying mishaps…

I am working with ING Robotic Aviation to develop a stabilized camera gimbal for their helicopter UAS. There is currently a gap in the market between expensive, military grade hardware and inexpensive hobby parts that we are creating a solution for. ING’s head office is in Ottawa and their Engineering department is located in Sherbrooke, QC where I am working.

Nice hangar!

I got to tag along on a test flight on my second day. They needed to do a range check on the telemetry and gimbal control. After some cell phone problems everything seemed to be working over about 9km. This is the usual flying spot on the private property of a local aviation enthusiast. It was cold and windy!
