Nice and fast! I saw the previous video with this plane many years ago. So, what is your flight duration with theses lipo?

[@Planekrazy1]

Thank you for watching long ago and again now. After 3-minutes of full-throttle flying with this setup the battery has 40% capacity remaining.

Where the heck this from?? How?

[@Planekrazy1]

These were sold under Durafly brand by HobbyKing about 11 years ago. I got this one 10-years ago and upgraded its power system for 3S and 4S. It is still fun to fly and now runs even faster using newer stronger battery packs versus those from a decade ago.
