Thanks to Simon for starting this challenge. It was super fun and I’d participate in any upcoming challenges. I’m not new to speed jets and I already have a jet (psycho) 90mm that’s been well over 200MPH so I’m familiar with how to make them work. This airframe shows definitive evidence it will surpass the Psychos top speed. I will add larger versions to this design shortly, definitely a 64mm (Currently printing) and a 90mm version.
