Stephen Zidek commented on Nicolas's blog post Partnership for independant SOLO based mapping solution (SOLO Mapper with Qx1 camera)
"I believe Mario meant attitude as in pitch roll yaw?"

"Sigh, I would buy this in a heartbeat for my mapping project if I could afford it."

Stephen Zidek commented on Alice Clayton's blog post What is Missile Mode Flight?
"Richard,
This is a neat design.  I like the idea of slimming down the avionics package to minimize its cross sectional area in horizontal flight.  Not sure what I'd use this for as I do not fly much recreationally, but it looks fun.
However I am a…"

Stephen Zidek replied to Dave's discussion Modelling buildings
"Dave,
In photoscan you must have the photos window up, and double click a photo to bring it up on the main viewer.  From there you can zoom in to add markers.  I usually use roof corners because they are visible from the ground and air.…"

Stephen Zidek replied to David Garrett's discussion Loss of altitude on 2nd flight
"Sounds to me like a mechanical problem like a prop loosening."

Stephen Zidek replied to Dave's discussion Modelling buildings
"Dave,
I start photoscan with two chunks.  One for the aerial photos, and one for the ground photos.  Sparse cloud on both.  From there I manually add markers to features which are visible both from the air and the ground.  I then align chunks by…"

Stephen Zidek replied to Dave's discussion Modelling buildings
"I have found a grid of nadir photos coupled with a "ring" of photos taken from the ground to be effective.  This requires manual alignment of the two photosets in Photoscan."

Stephen Zidek replied to Glenn Hollowell's discussion Quadcopters with top motors: what specific mods are needed? in PIXHAWK
"That's a no-go, probably won't have enough thrust to get off the ground.  Why don't you post a picture, we may be able to help."

Stephen Zidek replied to Rhosyn's discussion Iris+ & Tarot T4-3D in IRIS
"Hi Rhosyn.  Check out the manual.  There are indeed inputs on that gimbal for pan/tilt.  These are indeed compatible with the Pixhawk.  I do not know if you have any kind of FPV setup on your Iris+, but this needs a video transmitter and receiver.…"

Stephen Zidek replied to David Pulvermacher's discussion Landing gear activation
"No built in functionality for altitude based deployment right now.  If you check the wiki page there are some options for mode based deployment.  I assume you are working with 'copter, anyway.
It is also possible to DIY it, if you are ambitious.  I…"

"This is what I would do."

Stephen Zidek commented on Gary Mortimer's blog post USA Simple Commercial Flight Rules land in 60 days time
"Excellent, how do I get the certification?  Is it available yet?"

Stephen Zidek replied to Glenn Hollowell's discussion Quadcopters with top motors: what specific mods are needed? in PIXHAWK
"Glenn-  Actually, you will want to keep the prop direction exactly the same as a standard quad.  Instead, reverse the spin direction of the motors.  Since they are mounted upsidedown, this will make them spin the props in the correct direction.…"

Stephen Zidek commented on karen pineman's blog post Design Challenge to Aid Search & Rescue
"Well that's the thing, this contest is for (the most part) about pure 3D printed accessories.  The winners of the last similar contest were a set of pontoons, a gravity driven claw, a mount for your lego man to ride on top, and a cup to carry stuff."

Stephen Zidek commented on karen pineman's blog post Design Challenge to Aid Search & Rescue
"Aha, my kind of contest!  I am a mechanical engineer who specializes in UAV payloads; most of my payloads end up being 3D printed.  Very glad when I read the fine print and saw that the entrant retains rights to their design.  You can expect my…"

Stephen Zidek replied to Tony Galvin's discussion Looking for drone that can carry things?
"Well I wouldn't recommend ecalc for a newbie... especially one who want to buy off the shelf.  I actually don't particularly like that tool, but to each their own."
