Setting up the Spektrum DX 8 mode switches

 

This is what I found . The Spectrum radio seems to be very similar to the JR. the PWM values needed are here, the centre ones are what I came up with.



Flight Mode # -- Min. PWM -- Ideal PWM -- Max. PWM



#5 -- 1750 -- 1763 -- >1815



#4 -- 1620 -- 1683 -- 1749



#3 -- 1490 -- 1507 -- 1619



#2 -- 1360 -- 1428 -- 1489



#1 -- 1230 -- 1251 -- 1359



#0 -- <1165 -- 1172 --…

Primary Stage of "Winging It"

We are making quick progress on design, feature, and purpose ideas for our new autonomous concept aircraft. After sketching 4 possible models of planes that we could build, we have decided on one design that we are currently building out of insulation foam. After testing this much simplified version of our plane, we will propose changes that should be made to the design which should improve our final product.

 

The design we selected for our concept plane (picture of the sketch…

Blimp Drone Project

The DIYDrone Blimpduino's have been MIA for some time. A new version is promised so it will be interesting to see what those guys come up with next.   In the meantime some buddies and I have been building up our own arduino based  blimp drone.

Rutgers students using APM: "Winging it: the Plane of the Future"

We are a group of 5 students attending the New Jersey Governor's School of Engineering and Technology. The Governor's School is a prestigious program at Rutgers University offered to students the summer before their senior year exposing them to many different applications and varieties of engineering. Students are nominated by their schools to apply for the competitive program, which is provided at no cost to them due to funding from multiple companies, Rutgers University, and the NJ State…

AutoQuad ver 5.6







The distributors finally got in some of the new ST Micro STM32F2 series uControllers and I grabbed a few.  I was able to "shoehorn" one into a ver5 board as the pinout is close to compatible with the performance STM32F1 series.  Spent a few days rewriting the device drivers and am very impressed with this…

Interesting YAW on Quad

I found this picture of a quite unusual quad. This model has no counter rotating props, it uses some kind of servo controlled levelers on two sides of the booms. Never seen this before!

This heavy weight quad doesn't come cheap, prices starting at 29.542,90 EUR excl. Tax and camera mount.…

APM flying HDwing at FL1000...

...well, in my dreams and in X-plane only so far.

 

 

It's been quite interesting trying to get a flying wing to fly at such high altitudes.  There are all manner of complicated instabilities to overcome.  So far, the biggest improvement was adding a motor and propellor, not as any form of…

Yet another antenna tracker

 

 

Now that I got a couple of weeks' vacation from the army I finally had the time to work on some new hardware. Last week I made directional antennas for my UAS: thanks to IBCrazy for his fabulous BiQuad tutorial on RCGroups. Only an antenna tracker was missing.

 

Paparazzi GCS includes an antenna tracker -controller but as I've recently been…

Arducopter 2.0.25 - High altitude visit



I decided to see how high I would have the nerve to fly today.

 

Started in Simple mode, default PID values. Motor to motor distance of the quad is 64 cm, Turnigy Plush 18 A ESCs, DT750 motors, 1045 EPP props. When I tried to start descending I hit a snag - lowering the throttle in Altitude hold mode seemingly did nothing! If I'm reading the log right, the descend did not start until I switched to Simple mode. I increased the throttle before…

ArduCopter 2.0.28 Holy Shmoly!

Before going out for another late night test flight I decided to check for updates.  I saw the Arducopter 2.0.28 was already up.  I couldn't resist, so I went ahead and downloaded.  I knew from the previous nights flights I had a bit of tweaking to do.  I was really expecting to have to adjust some PIDs' after my first run.  However,  to my surprise I didn't have to adjust a single PID.  Excellent high and low level altitude hold.  Excellent Loiter hold for first flight.  Cam stabilization… Continue
