To show just how stable the techwing is while flying slow, I made the following video.
WS: 43 inches
all up weight:37 oz
motor: 370 watt 1100 kv
battery: 5000 mah 3s lipo
battery weight:14.8 oz
flight duration: 20 minutes
ma used: 1007
As you can see the techwing handles extremely well…Continue
The newly updated techwing design has achieved its maiden flight.…
I have to admit, I am a little fed up with the "ground stations" available on the market today. First off, good luck seeing most laptops or tablets at all outdoors. Second, good luck modifying or repairing your laptop / tablet. It can be done but its usually a major pain with a good chance of breaking something.…Continue
I wanted to post an update on the work I have been doing on the techwing design.
The new design is scaled up some to a 40 inch WS. It also includes real Grantz type winglets, a longer tip cord and fixed LE slots.
Techpod kits are going on sale from today until july 31st They will be available for $140 to all US and Canadian customers.
All newly shipped techpod kits will be shipped with these great upgrade parts which make the tail and wing very easy to remove and transport.Continue
So I have finally emerged from home built CNC machine purgatory. I finally have the new machine running, and it rapids @ 1000 IPM and gets around +- .003 accuracy. But anyway thats not the point of this post. I have been working on upgrades to the basic techpod. Upgrades that make it much easier to transport and assemble at the…Continue
So this is something I have been wanting to do for a while.
I am ready to pull the trigger…Continue
So, I have been working on a few upgrade modifications that will be available in about a week.

I am really getting a handle on openFoam. I have figured out the scale and mesh resolution problems I have been having. I can now produce highly detailed data sets of the air flowing over the current techwing design.
this is the airflow over the wing tip. Needs improvement. …Continue
I wanted to share my experience with openFoam.
I am using openFoam as part of the free linux distribution CAElinux. CAElinux makes it a snap to get a copy of openFoam up and running. CAElinux also comes with a plethora of open source CAE packages. After going through many of the available tutorials, I can now import my own geometries and run a case. I still have…Continue
I just wanted to show off what I've been working on lately for the techpod. Is a mechanism to at automatic doors to the camera bay of the techpod. This will allow people to mount a camera in the belly of the techpod and gather unobstructed vertical photos and still keep the camera protected during landings…Continue
A few months ago I recieved an email from Lorenz, main developer of the Pixhawk research project and the PX4 autopilot. He urged me to create a small flying wing platform. Around 35 inch wing span and around 500 grams. capable of carrying a small camera like a gopro or canon s100.camera and an…Continue

For the techpod 2.0, I want to have a high precision camera gimbal capable of continuous rotation in two axis. I have always likes the brushless gimbals that are…Continue
Hey everyone, so I don't have the APM tuned very well but at least its hitting waypoints and holding altitude and airspeed. I decided to get it flying and see just how long it would go. Here it the result:
this is the equipment list:…Continue
Hey everyone, Here is something cool that I have been working on that I think you may enjoy.
So, I had been pondering how to make an inexpensive variable prop. I was thinking about using a heli head from a hk450 or perhaps a tail rotor. I eventually saw a post here, on diydrones, where a guy was using a tail rotor from a HK500 (can't find post). I got inspired and found a HK600 tail rotor has the…
Got a little free time to get out to the field and do some flying yesterday. got a chance to engage the APM and see what it would do.
I was able to try out stabilize and RTH modes. both worked pretty well. Had problems with the OSD and after the first flight, I was getting glitches from the right aileron servo. I could not track…Continue
hear is what's happening next-
Went and flew at 60 acres today. only had time for a 20 minute test flight. the camera was out of focus and it was getting dark. This was flown with a foxtech 370 kv motor ,…Continue
They are here everyone!
That's a lot of techpods. I will start shipping tomorrow. Still have to work so the majority will be shipped Friday and Saturday when I will be having work parties with a few friend coming over for beer and pizza.
Thanks to the diydrones community for helping make this happen.

I have not found a place where the fixed-wing control for the PX4 is being done so I started this blog.
Above is a Screen shot from XFLR5. I use it to mathematically model the physical form of an airplane. I can then take this description of said plane and then start modeling the flow of air over the surfaces described is the model. You can then send…Continue
