Never grounded. Only 40 hours of use. The battery is exceptionally strong and lasts way longer than I can ride. Typically, I’ll ride at least three different sessions before re-charging. The handset needs even less charging.
I have the app on my phone, so EVERYTHING I’ve ever done on it, has been automatically logged. Kept indoors (in my living room).
Privately owned. I’m 150lbs, and I have been its ONLY rider. I’ve never allowed anyone to ride it. And, oh boy, tons of folks have asked me. Nope!
It has the 1100 wing. Battery lasts up to 90 monutes. I don’t crash a lot, so it goes for quite awhile—about 1 minute for every 1 percent shown on my control.
