Fr\u00e9d\u00e9ric Laude reported the near-flight condition of his team\u2019s CC01e<\/a> on Sunday, February 3 on the team\u2019s blog.\u00a0 We\u2019ve been following the progress of the airplane for several months.<\/p>\n

Carrying F-PYXQ’s wing and rudders to the assembly point<\/p><\/div>\n

A very small canard, with a pilot tucked into a slim, minimal fuselage just ahead of its small Electravia motor, the plane was taken from its hangar and assembled this week despite the cold, wintry day.<\/p>\n

Fr\u00e9d\u00e9ric reports that the team chocked the wheels and started to test motor and battery power, reaching 250 Amps and 3,500 rpm at the propeller.\u00a0 200 Amps gave 3,200 rpm, and 150 Amps produced 2,900 rpm, even with cold batteries.\u00a0 He notes that this is all much simpler than trying to run the original not-so-quiet two-stroke engine.<\/p>\n

Reconnecting CC01e’s canard<\/p><\/div>\n

For the video, the motor\u2019s top cover was left off, but will be replaced for flight testing, and a final spinner will cover the propeller hub after the first flight. \u00a0Unfortunately, the video is not yet on YouTube, but can be seen on the CCO1 blog<\/a>.<\/p>\n

Fr\u00e9d\u00e9ric explains, \u201cThe engine ran 25 minutes today and the battery was still charged to 40% after all these tests.\u00a0It is clear that if you push the knob, the electrons escape from the battery very quickly.\u00a0Recharging the battery is quick enough and only takes 2 hours.\u201d<\/p>\n

At the end the motor\/battery run-up and brake testing, F-PYXQ was put back in the hangar, causing Fr\u00e9d\u00e9ric to comment, \u201cWe do not yet have an electric plane, just an electric car.\u201d<\/p>\n

Following a few more tests, including measurements of battery discharging and recharging rates and operating temperatures, the team will firm up their aircraft\u2019s standing with OSAC (Civil Aviation Safety Organization), which carries out safety inspections for \u00a0the DGAC (Directorate General of Civil Aviation), which has already signed off on the canard’s general health. \u00a0Once they receive the final nod, the team will begin flight testing.<\/p>\n

We look forward to what this little gem will be able to do.\u00a0 It should mark a milestone in inexpensive flight \u2013 all on battery power.<\/p>\n
