Tornado 10

When I first saw these tornado T5 motors I was like "I need this". Then I searched a lot of 10 inch builds, first I used the iFlight XL 10 frame, but with this there is no room for bigger or double battery so I designed mine own frame. It's a true X frame with bigger core, this way I can use two 2200 mAh 6s battery in parallel. Without battery it's 1150 gramm, with two battery + gopro it's almost 2 kg :D It's sounds heavy but I think it's agile.
I had a really hard time with the pid tuning, after the 5 inch drones it was very hard, I killed 3 esc, broke a few props. Now looks ok, but still not perfect.

Update - 2020-03
Finally found a stable setup, not perfect but it's not producing random motor desyncs:

For esc:

  • Demag compensation max
  • Motor timing 27
  • Rampup power 15%

Betaflight:

  • TPA 40%
  • RPM filter min hz 80hz and set notch range to LOW
  • A bit more all the other filters ( bf 4.1 slider moved left with 1 step )

Now it's looks stable during fast (900deg/sec) rolls and flips.

If you need a version for other frame please tell what type is it and I'll make it :)

I wish the frame was for sale

I can share the plans for you, if you can cut it somewhere.

That would be helpful, because armattan and cnc madness would probably cut it for me and others without cnc mills.

The original idle % was 5.5, now 10.

Did 10% help with death rolls and desink ,

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
