Philippe Petit replied to Marco Colli's discussion ArduPilot vs PX4 programming
"Hello Socrates,
1. In my Oppinion: The PX4 stack by far.
2. I cannot comment on that... Also, well this really depends on how you integrate Python code. Do you want to send it via telemetry? Are you looking into a companion Computer?

Best Phil…"

"Hello Marco,

no, I dont know any other resources...

Phil Marco Colli said:
Thanks! I'm not planning any big project, only experiments in my free time (e.g. simple DIY programmed autonomous flights).
Do you know any useful resource for getting…"

Philippe Petit replied to muavdrones's discussion Current architecture of drone autopilots is wrong , Drone hardware architecture needs to be completely re-engineered.
"Hello,
well from the  control engineering side speaking, faster sample rate does not automatically mean more stability. 
If you goal is to get a Control System which is able to follow your commands more quickly (which I assume is what you are trying…"

Philippe Petit commented on Karan Chawla's blog post This week in Tiltrotors and Dynamic Modelling of Drones
"Hello Karan,
No Cascaded PID will do just fine I am sure, however you went through the hazle of finding a Dynamic Model and Designing a Simulation. Therefore I though you would do all that to validate your Flightcontroller with this…"

Philippe Petit commented on Karan Chawla's blog post This week in Tiltrotors and Dynamic Modelling of Drones
"Hey Karan,
very nice! I like your Simulation. However Debugging is one of the few things Matlab is actually good at. Have you seen the step-by-step Debugger in Matlab? 
Also which Controller did you use?Good work!

Philippe Petit commented on JLJu's blog post Kiel Like Total pressure probe
"Okay I see :). But I still did not see a drone fly a 40°AoA :). Hand flown RC aircrafts might reach this regime, however drones?
Still amazing work! Very interesting to follow :D. 
Looking forward to your flight tests, just be careful with surface…"

Philippe Petit commented on JLJu's blog post Kiel Like Total pressure probe
"Hey Jose,
well you would have to think about Eigenfrequencies as you did in one of your earlier posts, however with the amount of analysis you spend on your designs, that should be possible!What are your experiences with MHPs? 
Also I am still…"

Philippe Petit commented on JLJu's blog post Kiel Like Total pressure probe
"If your application really incoporates such high flow angles, why for example dont you take a normal pitot-tube and put it on a wind vane. Another realization would be a multihole probe, which would have to be calibrated first of course.Last but not…"

Philippe Petit commented on JLJu's blog post Kiel Like Total pressure probe
"Very nice work. However this could be hard to construct right? Some pretty advanced CNC machining has to be involved to construct one of these, with different assembly parts right? Do you have an application in which you need to measure flow angles…"

Philippe Petit replied to Euan Ramsay's discussion Best tricopter layout
"If all of your props are spinning in the same direction, your Tri will have a constant roll offset (because the tailrotor is constantly deflected to compensate for the additional torque).
Some people find this annoying. This is what happend to my…"

Philippe Petit replied to Michael Baker's discussion Pixhawk DSM satellite fail safe detection should be a top priority
"Hey, there are failsafe values. Depending on what you receiver emits when the transmitter is turned off you can program different actions. In example, land, RTL or whatever you like. Further reading on this can be found in the documentation…"

Philippe Petit replied to Philippe Petit's discussion Tricopter Crash with unknown cause. Spontanous System reboot?
"I would be very happy, if someone got another insight on this. 
I am still unsure what caused the system crash. Could it be caused by the 5V servo rail? I have the Power Module so I assumed that this is not an option. What do you guys think…"

Hello Guys,I was hoping that someone of you guys could tell me what went wrong when my Tricopter crashed today.The tricopter was hovering out in my garden when suddenly one of the motors switched to full power and flipped the quadrocopter upside…

Philippe Petit replied to AerospaceVlogger's discussion Supersonic, I'm going to do it.
"Hey AerospaceVlogger,
an interesting project you have there.
A question concerning your fuselage: Can you supply a sketch of your intended fuselage? You say it is not a flying wing, but "The wing tips will be the tails". I cannot quite imagine the…"

"Hey guys,
first things first: I absolutely love your project it seems to be really fun and also very well made!However I have a couple of questions: Which differential pressure sensor are you using? 
Also how is the mission planned to be? From what…"
