About Me:
I have been a cabinet and furniture designer for about the past 15 years. My wife and moved out to the west coast about 5 years ago. I got into RC with a coax about two years ago and found the ArduCopter project page a year later. There was no turning back.
Please tell us a bit about your UAV interest
I am fascinated with the coming together of electronics and mechanics that make a multirotor possible. Add in the autonomous ability to perform tasks and take action opens up worlds of possibilities.

"Hi Thomas,
I would be glad to provide that if you want to email me at sean@aerotestra.com"

"if you were to build a Arduboat, high end "fish finders" can do amazing resolution with new types of "ping" sonar and create surface geolocated surface models in real time.
Ill bet if you build it they will come....asking for bathymetric surveys.:)"

On July 18 2016 University of Hawaii at Hilo's SDAV Lab, under a COA from the FAA, operated multiple UAV flights over Puuhonua O Honaunau National Historic Park. A first since the ban was established in June of 2014.The project was spearheaded by…
"Relative to its predecessor (Mk 09 non ducted) at the same angle the speed was much greater. Haven't tested in significant wind, but I suspect from initial tests wind drag is going to present a factor to be considered. How much is yet to be…"
"i sould have described it as a dual motor setup as opposed to coaxial. The ducts are designed to hold either one or two motors. I had been interested in trying out some of those coaxial motors when I saw them start to be available. Do they operate…"
"we won't attempt to quantify the gains in efficiency until the 2nd version of the ducts are complete. The first were a proof of concept, but the resin content was relatively high so it was clear a better production method be developed to reduce…"
"I found there were a few issues that were resolved to some extent by replacing all the avionics (pixhawk, power module) after the first maiden. So this was actually the second flight. I think there were some issues with some of the hardware in the…"
"Thanks Bill,
We have been working on this design for several months and the processes of manufacturing the duct that was light weight, but able to hold its shape under the stresses encountered during flight with the propeller tolerance required to…"

"I am replacing the controller to start with. I have always had great success with AC and the hardware. Pixhawk seems to me to be a very robust reliable controller and the Channel 6 tuning allows for the "in flight" adjustment of each PID value. I…"
"Very interesting. I guess mine is actually kind of small. "
"Ed,
I noticed a tremendous amount of ground effect to be sure. It is a big quad and I am trying to keep it in one piece as I get it dialed in but I have noticed it calms down a bit over about 4-5 feet altitude.I added more vibration damping under…"

"Its all brand new. I suspect from some other posts it could be related to the PM. I have to use a HK power module for the 6S"
"I don't think it is as clear as that. The motors and direction are correct. I have built more of these than I can count and have never seen these types of behavior. Currently i am getting ACCEL Inconsistent pre arm warning. The compass is spinning…"
"Here are the RCOU for channels 1-4"
"Good picking up on that. I don't even know if would have made it off the ground in that state. However I did check and all props are in the right orientation. That picture was during final assembly and it escaped me until after i had mounted the…"
"Every effort was made to try to install the motors vertically in each motor housing. I will pay close attention to this possibility during test flights tomorrow. Thanks for your response. "
