Default MotoPhan Dual Pan/Tilt Fan Concept Flying Jet Motorcycle

This is my attempt to come up with a better flying motorcycle design than what’s out there. I am a long-time motorcycle rider, mostly high-performance sport bikes. I know the joy of leaning into a turn and the limitless acceleration. This is the only design that I know which can move forward without tilting and can lean while turning, which will make a real aerial motorcycle riding experience possible.



The first couple of flights have been a little eventful, with a major crash. So, I replaced the ECSs which I believe caused the problem and re-tested today. I am keeping it low and close to make sure it can sustain a longer flight before taking it around the park. Looks very stable despite some wind.



I can move forward and back with differential thrust using the pitch stick. The fan tilt is controlled by the 5th channel. That will act like the clutch of a normal motorcycle, initiating a forward move without tilting the unit, making the awesome turns possible.



There will also be an aerodynamic addition to the design, after I get a chance to fly it faster and understand the areas to support.

A faster flight as I build my confidence in the unit and the design. Some higher speed passes at the second half of the video and even some wheelies (I tilt the fans forward and pull the pitch stick back. The unit lifts the head up and does a wheelie). I am not even tilting the fans one third of the range yet. Exciting stuff

I had a nasty crash after the last video. My guess is that the receiver lost signal resulting from the thick carbon fiber frame. So, replaced the RX and with a better long antenna one.



Testing the new aerodynamics. The first design didn’t work out. So, I decided to go with my first instinct (which I ignored before) and changed the design. This design should minimize the impact of the crosswind.



Successful test. The unit feels pretty stable when I tilt the rotors forward. Definitely slowed down, as a portion of the speed is being converted to upforce.



Things to work on: 1- The fans are not tilting in 100% synch caused by the design. Will need to work on that. 2- The added surfaces reduced the hovering stability. I will need to work on the PID again.

More crashes, more lessons learned.



1-When rear fan tilts too much the battery/canopy combination is cutting the airflow to the fan and the unit stalls. So, I made changes to tilt the front fan more and the rear fan less. I may cut the back of the canopy if needed or add a structure to direct the air to the fan intake at higher speeds.



2-Played with PID to fix the hovering stability and the fan tilt speeds.



3-Changed the design of servo/fan connections for added strength.



I still need to mount the tilt servos sturdier to handle the forces in the flight better. More work to do. Just wishing no more crashes.



The aerodynamics work. The unit slowed down and I can feel the lift. It leans into the turn by itself when I apply yaw (no roll input). Now I need to revise the tilt servo mounts and get it to higher speeds.
