MC commented on Duy Pham's blog post Change Hex to Y6
"Nice platform and nice flight
How long you can fly with 2kg payload ?
Do you count battery weight as payload weight?
What is your empty (without payload) weigth of your system?"

Hey,I want to ask expert advise on a long endurance (about 40 minutes) heavy lifter (1550gm camera) multi-rotor platform.Can you speculate or advise me what would be the good starting point of building a multi-rotor (quadrotor, or hexacopter or octa…

MC commented on AirviewLive's blog post Shielded hexacopter is safer than the rest
"It looks cute.
3.7kg empty weight sounds too heavy; how long it flies (i.e. what its endurance)?"

Hey,Take off Weight (TOW)  and flight endurance are inversely related attributes for most of UAV platforms.I want to build a multi-rotor UAV platform capable of lifting 2.5kg payload (+ weigh of platform+batteries+electronics etc) and try to hover…

MC left a comment on Telemetry over cellular IP
"Is it legal (in US, Europe, NZ and in Australia) to use cellular network from an airborne (manned or unmanned) platform?
Here is a statement I've found "According to current U.S. Federal Aviation Regulations, the use of cell phones on any kind of…"

MC commented on Earl's blog post Raspberry-Pi for autopilot ?
Yes, I agree with you that one can find many high-level applications that can not be performed on Arduino. Vision based obstacle detection could be one of them. I assume, in order to use OpenCV on this card, the only way to input video signal…"

Hello Everybody,Can anybody advise me if there is a method to charge LiPo batteries really quick (less than a minute, instead of tens of minutes)?Is there any other battery type, other than LiPo batteries that can be used on RC planes and can be…

Does anybody worked on the position estimation of a hovering UAV (quadrotor, helicopter etc.) using external multiple webcams+PC and a custom OpenCV (or MATLAB) application in indoor environment ?(Yes, I'm trying to make a poorman's version of…

MC commented on Chris Anderson's blog post Kinect Gesture-Controlled RC helicopter
"That is very good! Well done and than you for sharing with the DIYdrones community. 
Where can we find the IR control data transmission protocol details for S107 RC Helicopter? (or can we get your IR transmit sketch as an example?)"
