Are you going to take it further, like making it fly horizontally? Somehow it reminds me of the umx hyper taxi!

[vaalleon]

Yes, I did that on my single fan unit. I had my first horizontal flight today. Check below link:

Going through some old files, I came across to the last footage of my twin unit that I never published. This has been one of the most reliable and balanced units:

Thanks for watching!

The new dual unit. Full carbon fiber with new thrust vectoring system. Will be equipped with GPS and a camera gimbal following further tests.

Made some design changes along the way and fount the right balance for the unit. This is a longer flight after a couple of crashes, major one resulting from an electrical malfunction. Re-adjusted the system voltage, increasing it one full volt, which seems to have solved that issue. Replaced the 3000kv motors with 3200kv ones. Took out the GPS that doesn't seem to work. I will test and fix that later. The flight characteristics are showing the balance of the unit is almost perfect. Maybe a couple more little tweaks.

However, the battery, even though having plenty of MAHs, is still lacking the C rating. Towards the end you will see a closeup of a semi-crash. No damage done. Re-flew it again with the remaining juice. Uses about 80% of the total juice of the battery for this flight. The battery slightly puffed during the flight. Thinking of getting a 70C battery with a slightly smaller capacity to finalize the project...

That is really cool. I lose orientation very quickly on a quad, once it gets about 20 yards out I cant tell left from right, front from back. It must be that much harder on this trust machine.

Thanks bud! Yes, exactly. All good as long as you are moving but the moment you stop moving at a far distance and lose orientation, it is quite tough to get it right. There are ways tho to get over that problem. However, not a priority for me at this point because I only fly to test units and usually don't get them too far.

Awesome power of Genace 70c lipo! OMG! Does it ever lose any power until the last minute??? NO! You pay double, you get triple. AND THIS IS A CAR BATTERY WITH HARDCASE!!!! What else could I want? It doesn’t get damaged! Forgive my excitement on this. But I have been spending hundreds of dollars for the right battery and I finally found it.

Before this flight I had a couple of crashes. At first, I didn't get what was going on. Then I realized that one of the ESC was giving in due to heat during the flight, and reducing the power to protect itself, which was causing the unit to lose balance and crash. Increasing the KV ratings of the motors and extreme heat over 100 degrees didn't help. So, I pulled off the many years old simple and bulky hobby king ESCs from one of my old units. These ESCs cannot even be throttle calibrated but they sure did the job. They got a little too hot but I have some experience and ideas to resolve that. Installed aluminum homemade heat sinks on the ESCs and they worked very well. This flight is over 5 minutes. The theoretical flight time of the unit is 6 minutes. So, I should land between 5 to 5 and a half minutes.
I also installed a small cam with a 1 axis servo gimbal. At the end of the video there a couple of pieces of aerial video.

I consider this mission accomplished

This unit looks badass in the air. Almost scary. I think it is because of its potential. It is VERY responsive. Vectoring the fans instead of using nozzles improved the responsiveness compared to my older twin units. I cut the flight short because I realized the fans fluttered a little. I am looking forward to the day that the tuning is complete and I will fly this beast at its limits…

Meanwhile working on the wing with the carbon reinforcement.

It took me 7 broken impellers, 1 broken fan, 1 broken servo, tens of tests & crashes, unbelievable amount of frustration and tens of different tunings to get this beauty to fly. It was worth all after flying it!!! It flies like nothing else. I don’t think there is wind that it cannot beat despite its size, except a storm or something I am just touching the sticks for it to go as fast as does in the video!!!
