Today was the very first time I flew my Sportster EP with just one 3S1P and did so for a little over 2 mintues as I had forgot my parallel harness today as I was excited to get some inflight measurements with my GPS receiver to record the maximum air speed of my Sportster EP with the existing modified Brushed power system.
Well, it registered 74.5 MPH!
I will try to install the GPS Receiver in the Sportster's Cockpit and certainly parallel the APEX Li-POLYs next time to see what kind of air speed the GPS records! I suspect a higher air speed as the parallel setups will not allow the Under Load Voltage to go below 11 Volts.
Here's some pictures of my flight today at the CLub Field.
