Apparently this is an e-bike!? Classed as a quadricycle, limited to 28 mph and doesn't require a licence to drive.8mo ⋅ skyersjet ⋅ r/ebikes
William Schaffner was sent to intercept a UFO over England. His plane was found in the sea but his body was missing. The cockpit was sealed shut.3yr ⋅ skyersjet ⋅ r/UFOs

Williams X-Jet. This final attempt at Jetsons-style travel actually worked but top brass decided that a boring helicopter was more efficient. It did however end up in Metal Gear Solid 34yr ⋅ skyersjet ⋅ r/WeirdWings
Was this guy ahead of his time? He designed these notorious flops in the 80s and 90s, one of which is very similar to a modern ebike.8mo ⋅ skyersjet ⋅ r/ebikes
What do you think of my project? 3D printed electric ducted fan. 15kW motor.3yr ⋅ skyersjet ⋅ r/aerospace
Dornier Aerodyne - Designed by Alexander Lippisch who didn't believe in wings because he thought they just added drag. Instead the ducted fan is the (circular) wing with flaps to divert air downwards for VTOL like a Harrier.3yr ⋅ skyersjet ⋅ r/WeirdWings
You can open it up and service it just like a real jet engine! Found a loose blade during inspection, bad news on 14s...3yr ⋅ skyersjet ⋅ r/radiocontrol
3D printed electric fan project. It uses a 15kW brushless motor connected to a 200A, 58V ESC and the blades are 3D printed with PLA.2yr ⋅ skyersjet ⋅ r/diyelectronics

Can anyone recommend a 6s lipo that won't sag at 200A? These ones are down to 3.2v/cell by 160A.2yr ⋅ skyersjet ⋅ r/Multicopter
I put the wires the wrong way and the fan spun in reverse sending my EDF flying off of the stand.3yr ⋅ skyersjet ⋅ r/radiocontrol
Preparing for 14S, 200A. Gotta make sure all those bolts are tight, or else...3yr ⋅ skyersjet ⋅ r/radiocontrol
I'm trying to design an intake for a fan but I don't have any CFD software. Do you think the air will make it around this curve?3yr ⋅ skyersjet ⋅ r/AerospaceEngineering
Air intake. 180 hour print. It was a failure but I learned how to print and glue together large toroidal shapes without it breaking or flexing too much.3yr ⋅ skyersjet ⋅ r/functionalprint

Miles M.52 cancelled British supersonic aircraft that would have been the first to break the sound barrier. The Americans later borrowed the research for their own attempt3yr ⋅ skyersjet ⋅ r/WeirdWings

I was right! At the same RPM, lower voltage is more efficient. What I was wrong about though is that it's not at the same throttle.3yr ⋅ skyersjet ⋅ r/diydrones
