NOTE yes this is something I made in irl so at the time about 2 years ago about 2 weeks before this I had made my first rc aircraft the j.co phantom useing a 2 5 cell batteries and a propeller and brushless motor from my shop bought rc plane and after a bit of tweaking it handled well and was really agile. on its third flight I took it up to about 1000ft and dived while my friend used a speed gun to measure the speed. it hit 60 mph. later that night he bet me £50 that I couldn't make one go 100mph thus the red devil was born on a dive it hit 112mph so I won the bet I made 2 different ones unfortunately the original witch at the time I gave more volts than it needed exploded mid air but the second one witch this is based still flys today.
