Mark commented on Marco Robustini's blog post "PX4 VTOL" - Full automatic mission with multiple transitions
"Fantastic transition, very smooth.  Had to out a coat on though, just watching made me feel cold!"

Mark commented on Dan Kanes's blog post Drone Racing League - Public Debut
"I understand that the connex system was tested but struggled once you went past a couple of concurrent users."

Mark commented on Josua Benner's blog post Arrow Drone - The FPV Racing Drone: An Entry Level Racing Drone That the Pros Will Love, Too
"If I read it right, Josh has confirmed its done down wind and or down dip.  The fastest we have done on a traditional BO style frame was 126km/hr with 4S 2204 kv1960 and HQ6045. This frame (ours) has ridiculously drag. Add a bit of wind and down dip…"

"Would love to know which props you are you using to get that speed?  We have got to 154km/hr on 4S but the HQP5045BN NGF props we use explode under the stress.
Cheers

Mark commented on OneDrone.com's blog post OneDrone.ONE - Modular Drone System
"Lovely renders.  I like the aerodynamic arm supports.  Quick question, in winds and multi mode, how do you think this will handle/effect performance. Particularly when the craft is at an angle continuously.
Cheers

Mark commented on Nick Arsov's blog post Ardupilot/PX4 communities : DIY hardware Innovation is still alive and well - the new XRacer V1.0
"Hi Leonard,
I am very exited about the board as well otherwise would not have posted. I make no suggestion that this board or any other is deficient. My comments reflect the pure fpv racer perspective, see final comment....I am sure there will be…"

Mark commented on Nick Arsov's blog post Ardupilot/PX4 communities : DIY hardware Innovation is still alive and well - the new XRacer V1.0
"Great work Nick.  A few general comments.
a) Pls keep it ultra simple. FPV racers are bare bone go carts. Keep all unnecessary sensors off the board, eg. baro. FPV racers need only the gyro and accel.
b) Some sort of wireless connectivity is useful…"

Mark commented on MHefny's blog post To Tricopter or to Quadcopter ..... That is the Question
"Hi Gary, 
Apologies, I missed the point re non mechanical mech tilt.
BTW, the aerodynamics of arms are less of an issue with the newer quads as the arms are around 14mm wide but thicker.  They would be even less but for the escs being around 13mm…"

Mark commented on MHefny's blog post To Tricopter or to Quadcopter ..... That is the Question
"Hi Guys,
Our experience is mostly with designing/building/selling racing quads although we are developing a mini tri at present because they are cool and fun!
Thought I would make some observations:
a) the popularity of mini tri frames has fallen in…"

Mark commented on Jimmy Oliver's blog post $99 Drone Parachute on APM 3.3
"Hi Jimmy, thanks for posting.  A couple of ignorant questions if you don't mind.  How do these systems avoid entanglement with the props?  Also, possible issues with deployment where the attitude is not ideal, eg. upside down or free wheeling?"

Mark commented on Charles Blouin's blog post Brushless Motor Dynamometer from RCbenchmark
"Great, thanks for posting.  How did you go with the vibration causing the load cell to oscillate unacceptably when using it as part of the structure to support the motor?

Thanks 
Mark"
