Coptaire commented on Ian Lyons's blog post 30 days to build a radical VTAL drone
"I am not impressed at all with these "placebo" ducted propellers.
Using a 2 blades propeller where tip is not even close to the duct won't suppress the tip disturbance.They could at least 3Dprototype their blades, and expose what a company can make…"

Coptaire commented on Tommy Larsen's blog post Full size Y6 Air-Scooter
"3 engines? 6 engines? Nooooo . 2 are really sufficient, but with years of research! martinjetpack.com
Why not booking a flight first?
(to get a down-to-earth feeling, of course! :-)"

Coptaire replied to Trevor Strand's discussion Bixler 1.1 Cockpit APM 2.5 + uBlox-6 + Turnigy 9x Reciever Mount Tray in 3D Printing Drone Parts
"Hi Trevor,
Perhaps you read my post about propeller guard I made with Shapeways last year.
Now, I print quite detailed parts myself
If you wish it, send me the STLs of this project, or others, and I can print them for you, with pictures of the…"

Coptaire replied to cedivad's discussion I achieved a 640x360 live streaming over cellular network with a 500ms lag today...
"Nice setup, but why not encoding to H264 using the camera processor ?"

Coptaire commented on Coptaire's blog post Propeller Shroud Project
"Hello Cory,

Indeed, assessing the real performance of the rig is why am designing this, to get a real life configuration, and see the advantage(s) in this range of dimensioning (Reynolds number).

Project is going well, taking advantage of 3D…"

Coptaire commented on Ellison Chan's blog post 3D Printing My Own Personal Robot Servant
"Ellison, your idea of sharing a grouped bulk filament order is great!
Perhaps, other people are interested in joining, just PM us.
I print with a Makergear M2 and 1.75mm ABS mainly."

Coptaire commented on Ellison Chan's blog post 3D Printing My Own Personal Robot Servant
"Congrats Ellison!
you could add this 3D printed hand InMoov, your picture says it all!
I probably try the same chinese filament supplier, buying 25kg of ABS to reach a good deal on shipping cost.
3D printer is UAS/UAV best friend!"

Coptaire commented on Chris Anderson's blog post GPS loss plus faulty inertial code caused fatal Camcopter crash
"Navigation aid, GPS being of one among others, is not concerned by aircraft piloting.
Aircraft piloting, or vector management, apparently assisted from the ground.
All kind of aircrafts were already flying well before GPS became available.
Talking…"

Coptaire commented on naish's blog post Tracking antenna
"@George
900mHz and 5.8gHz have very different propagation pattern, one being quite 'omni' (900) and the other being "line of sight" (5.8). For this reason, this wide band antenna you would wish is hardly conceivable.
We suggested to couple an omni…"

Coptaire commented on naish's blog post Tracking antenna
""24dBi High gain dish antenna" for which frequency range?
For a ground station, often an omnidirectional is combined with a directional, switched by diversity, so on top of a moving vehicle, the same combination of directivity would seem a good…"

Coptaire commented on Scott Thompson's blog post Implementing ESC Fail Safe
"@Ellison.
Apparently, the APM is in quad config coax, X8. But, only 4 motors are used, the 4 remaining are like a backup. A quad with upper props spinning, and bottom ones unpowered. The 2 pololu boards are configured to react differently, based on…"

"Who knows, it could become a remote-controlled Open Source project!"

Coptaire commented on Gary Mortimer's blog post The bar has been raised
"The bar has been raised, from an AP multirotor point of view.
The bar has been lowered, from an heli crew point of view."

Coptaire commented on Coptaire's blog post 3D printed Propeller Shroud Kit
"At this scale, no problem of rigidity! The shroud could almost contain your printed quad."

Coptaire commented on Coptaire's blog post 3D printed Propeller Shroud Kit
"@Ellison
Great price! But does frame rigidity is enough? when full equipped and flying?

Beyond protective aspect, this shrouding could reduce the blade tip vortex (with minimized gap), the vanes are equivalent to a propeller with a null speed. The…"
