About Me:
I have been flying RC planes/helicopters since I was a child with my father. I have enjoyed it and this seems to be a natural extension of that interest.
Please tell us a bit about your UAV interest

"The variable pitch portion was an adaptation of an airplane variable pitch design called "showstopper". I then used a 450 tail housing from a heli to hold it on a boom. The center plates were custom cut on a CNC out of fiberglass plate. The design…"
"It is true that you will lose a little bit of efficiency with a belt reduction but it will not be a huge loss. Overall you would actually gain efficiency because you can swing a larger prop. Although your maximum airspeed would be reduced as a…"
"E-flite makes a variable pitch prop called showtime made for direct drive on airplanes. I actually adapted this for the first version of my variable pitch quad. Essentially it replaces the motor shaft with a hollow tube so you can run a servo…"
"The V-tail has not flown yet and I don't have a flight controller setup and working. Right now I have an APM and a KK2 flight controller. I would prefer to use the APM and that is what I used on Version 1. I didn't do enough research yet to see if I…"
"On version 1 which is an X configuration I had to make significant changes to the PIDs and I had to reduce the PWM rate to 50Hz from the default 200Hz. Other then that I did not make any changes. On version 2 with the V-tail I will most likely have…"
"That is a really interesting solution that I was not aware of. I think the only way to make practical auto rotation in a design like this is to put a one way bearing in each pulley on the rotor shaft so that you bypass the drive line drag. Even by…"
"Thanks for the comments everyone! I am familiar with the Stingray. I have not seen it in person but the pics/videos I have seen are very impressive.
@R_Lefebvre, The rotational mass of the spinning armature and small pulley in the center is not…"

I have a long history of being involved with R/C planes and helicopters and moving into drones is a natural extension of that. However, until recently I had little exposure to quad copters and I had the opportunity to see them fly at a drone meet.…
I am working on a variable pitch quad design and I am running into some trouble tuning it. I have worked on the PIDs and got it to the point where it does not oscillate so that I can fly it. Here is a video of a test flight…
I am nearing completion on the airframe side of a single motor variable pitch quad copter design and I need a little help on the software side to get this going. My intention is to use the variable pitch to control attitude and altitude and then run…
I just loaded the Beta 1.01 code and went for a flight today but ran into some issues. I setup the modes to be manual, stabilize, and auto. I loaded a few way points and once in the air I put it into stabilize mode. However it took over the throttle…
"I don't know the exact UAV rules but I do know about the airspace rules and I can share that information with you. Its a starting point at least..... The rules vary from airport to airport, for example a large airport like LAX has very restrictive…"
I am setting up a APM with a F27 Stryker that uses elevons. I am working with code revision APM 1.0 Public Beta. I have everything working well in manual mode and I used the reverse dip switches to get the controls to react properly to the…
I am working with the Ardupilot Mega with a 3S lipo and I am trying to get the battery voltage to display in the telemetry. Currently all I am able to get is "Low Battery!" but the battery is fully charged. I soldered the 3.9k resistors in the 1,2…
"Martin,
Sounds like an interesting project. I recently built a project like this but to track bird migration patterns. I caught some hawks and put on GSM based tracking devices which send me an SMS with location information. I have an SMS base…"

I am working with a Ardupilot Mega using a U-Blox GPS but I am not able to get a lock and I need some advice on how to troubleshoot this. I have read that the first sat lock can take as much as 15 minutes with this GPS so I have left it outside for…
