Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Quite a windy day, great opportunity to test the skills of the little watcher and get some closeup footage of the flight, thrust vectoring and active wing compensation. Amazing little thing started the build journey very rough, not even hovering properly and crashed tens of times. But now it turned out to be the most skilled watcher I have built, which I have learned configuration tricks from which I will use on the bigger units. If you like aeronautics and flight in general you will definitely enjoy this video, especially the close-ups. I changed the attack angle setting multiple times during the flight so some passes have the higher and some have the lower attack angle. https://youtu.be/5gVjoBBGBZc |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Not sure if you'll find this helpful but I hope it will be at least interesting. RC Test Flight made a single motor (final version) vertical takeoff and landing "rocket" |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Today is windy, perfect for a test. I was getting awesome horizontal performance and smooth transitions, but the vertical flight performance didn't impress me in the first test. So, did some further tuning and did this short test. As long as I don't get the wind from the back vertical flight is satisfactory as it is. Ready for FPV. https://youtu.be/66uN87IYlGQ |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Took this video to see how the active wings work during a flight. Windy day and the gyro compensation is pretty cool. https://youtu.be/ITfSvbsX3nQ |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Last two test flights for fine tuning. I re-designed the rear stabilizers in the first and additionally re-tuned the wings in the second flight. Both improvements made a huge difference in the quality of the flight. I think I am pretty close to installing the camera. One last thing that I want to test on this is the negative attack angles. The previous units are not capable of handling that. But this unit has a special wing geometry which may be capable. Hope I don't crash it  https://youtu.be/1Sz2Fm5c0Sg |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan This is the 10 min flight. Still have some minor issues, with flutter and balance. But overall it was a good flight. Used 90% of the battery, which puts the estimated maximum flight time to 11 minutes. Will make a couple of minor changes and try to strengthen the frame a little bit to avoid resonance. https://youtu.be/sGlNdSuohQc |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan I re-built some parts of the unit due to some build errors. Re-tuned the unit and took it out. A much better flight. There is a little wing flutter when hovering and a little bit of wobble in turns. I'll look into these issues. Other than these the unit performed pretty good. I took off from the ground and transitioned back and forth twice and I wasn't very mindful of the energy savings. Still I only used 1760 mah for this 6 min flight. Which puts the estimated flight time to over 10 min for this particular flight. It's time for a 10min flight test and see how much juice gets left in the battery https://youtu.be/nl9sCpUVDRI |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan This is the new unit that I built to reduce the weight and get a better hover performance. I used balsa, foam board and reduced the carbon fiber usage significantly but still used it for some reinforcements. The unit came out 70g lighter than the previous one. Not bad! In this flight, the horizontal didn't go very well. The unit kind of dived and didn't fly in a balanced manner. So, I decided to use the remaining battery for a hover test. The unit can sustain a full vertical flight but still feels under powered. The transitions are spectacularly smooth, and the wings create great lift. I need to make some changes and re-tune to get the horizontal flight going. I am hoping to get well over 10 minutes flight time with this new unit. https://youtu.be/IoYJVAXAyfw |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan Testing the vertical capabilities of the unit. One thing that I know it cannot do is fly backwards but everything other than that looks good. Tight maneuvers and sideways look successful. I am in the process of building a new improved autonomous unit with arduino support. That may have the capability to fly backwards, too. The significance of this capability is to be able to handle the back wing while hovering. In the current state I always need to face the wind or take it from the side. |

Re: Single Fan Thrust Vectoring VTOL Project - MonoPhan AT LAST +10 minute EDF VTOL unit!!! Decided to take it out for a longer flight to test the flight time and good thing I did. It used 1693mah for 5:20 minutes, which puts the estimated flight time approximately to 9.5 minutes. When you account for the marginal efficiency improvement over the take off and landing taking less portion of the overall flight, a longer flight will definitely exceed 10 minutes. This proves the design successful... Now need to build a better and lighter unit of the same concept |
