With the aid of an actual Northrop Grumman engineer, we designed and tested more designs than we care to share. In the end, both us and the engineer learned quite a bit about how ducts perform on these mostly hovering crafts. There will be a more extensive video about it in time but you can basically view a duct as an item similar to a prop. It has just as much detail and nuance in it’s design in order to achieve any given performance. We’re designating this as the third design in the series and is far better than anything before it with improved control, power and efficiency. The rest of the details are too much to write out here…..standby for a video in time.
Note: Tge ducts do NOT fit the frame perfectly on purpose. When screwed into place the ducts are held under tension and are somewhat oval. When fresh props are inserted, they will rub against that walls of that duct. Arm the quad and get the props spinning, then hover for a few seconds to allow them to grind into place. It will be loud during this process and then it will quiet down considerably. This sort of fit actually improves efficiency a but but more importantly, reduces overall vibrations in the system because it's all held under tension. Again, this imperfection is on purpose and 100% if the ducts do not fit perfectly.
- Improved ‘duct-foil’ for more thrust, better efficiency and no loss of control
- Printed from PTEG which is fully heat stable
- Durability is much better than PLA but it’s still a thin print
- Brass inserts not required but included
- ~13g per duct without brass inserts
Those are awesome really more durable and flight is smooth
Aesthetically pleasing, great fit for 2203/04 motors. Sound quality from the propellers has improved. A little more durable than V2. Took a bunch of tree bonks no problem, concrete column chipped it up.
Held up really well during a punishing shoot chasing skaters around. And flight characteristics (using frame, motors and ducts bob recommended) is just pure joy.
Hoping more of these are in stock soon!
Using these on my CineSplore and my Cloud149 and the difference from stock plastic ducts to these are a major improvement to sound and performance.
Hint: before placing brass inserts in ducts, line them up on arms so pre-holes match. I pre-drilled one duct because the holes didn’t line up. If not they will oval on arms.
The V3's out perform the V2's. More predictable, smoother flight characteristics.
I asked a 'printing nerd' friend to look at these, and he said they looked really good. Maybe printed a little fast and the layers weren't sticking together as well as he would have liked but that's just cosmetic. For what we used them for they work great.
