Loving the SP140, using it for 90% of my flights these days. The biggest drawback in my experience is flight duration. No matter how much I try to be gentle on throttle, I can’t seem to break the 40 min mark without the motor cutting out.
Ideas to increase flight time?
Perhaps decrease flying weight, mine and equipment? Could fly without reserve, lights.
Using a vario to maximize climb per thrust/battery draw?
Perhaps a different wing? (I typically fly Ozone Spyder3 26m).
Is there new battery technology that might be available in the near future that could be applied for this application? (Let’s go Elon!)
