MarcS commented on Gary Mortimer's blog post HABLEG (High Altitude Balloon Launched Experimental Glider)
"Hi Dan, it´s a custom design to fly well at 20km (think Re-number..) and to house the equipment well insulated."

MarcS commented on Gary Mortimer's blog post HABLEG (High Altitude Balloon Launched Experimental Glider)
"Hi Nick, at 20km the plane just flies faster (50-60m/s, 13m/s at ground level), and actually the control surfaces are more effective under these conditions!! We underestimated this effect a little bit which led to a roll movement you can see in the…"

MarcS commented on Gary Mortimer's blog post HABLEG (High Altitude Balloon Launched Experimental Glider)
"Hi, nice to hear many people are interested in the topic.  Let me add some comments as one of the HABLEG crew members.  Flying from that altitude is a really great experience and a massive challenge. If you get the chance, go for it! Our…"

MarcS commented on CrashingDutchman's blog post Stepcraft 2: a milling, carving, cutting, engraving and 3d printing machine
"People should not think they save buying two dedicated machines in the end with this one... It is a nice hobby cnc mill (but there are many on the market). As a 3D printer it might not be nice to use. Speeds are too slow compared to dedicated (belt…"

MarcS commented on Rob_Lefebvre's blog post Canada to Regulate Recreational Flights Like Commercial
"Is it just me or does this part of the document contain a "wrong equation"... - RPA for recreation = model aircraft - model aircraft community != recreational RPA users != RPA industrie (commercial) Anyway, I can hardly see a point in…"

"Hi, interesting idea. Back in my head I did remember something similar. After some search it turnes out it actually was long ago. It is called Keyence Revolutor by a japanese company, which actually also sold mini quadcopter over 20 years…"

MarcS commented on Adrien HADJ-SALAH's blog post BreezeUAV : An open-source autopilot for UAV
"Hi Adrien, nice project, I know the feeling of developing something from scratch to work :-) Just an advice about the XBee868 from my experience: Take care about the duty cycle with these units. It´s limited to 10% and if you exceed it…"

MarcS commented on Rob_Lefebvre's blog post New Transport Canada UAV Regulations Arrive!
"Did anyone notice the DO NOT section saying: "Do not fly closer than 9km from built-up areas" Ok, this leaves a lot of space in Canada :-)  But for many applications it means to ask for an SFOC, doesn´t it?"

MarcS commented on Chris Anderson's blog post ESA does another copter-rover drop, this time with awesomely over-the-top music
"Hey guys, whats the negative attitude about here??? There is a group of researchers showing an experiment using a multicopter. You should use it as a positive example what the technology can be used for... (Even if it´s not Ardupilot :-) And…"
