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 --…

So here the setup;

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…

Some very interesting research done by Rick Cory that uses a single control surface to land a glider on a cable.  Check out this link for more information and videos:

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. 

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…

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 controller's performance.

I was able to bump up…

MatrixPilot 3.1 is released. The project continues to mature, with a fantastic IMU that is still moving ahead with deep research from William Premerlani. Ben Levitt continues to add amazing features such as the built-in firmware for the OSD hardware that can be attached to the UDB3. This means the UDB3 can display it's internal thinking (such as next target…

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.…

...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 thrust device, but as a gyroscopic stabiliser!

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…

ACM2 makes my tricopter the most stable FPV flying experience I'd tried.

RTL mode was turned on at 3 min 28 sec in this film and turned back to stabilized mode around 3 min 49 sec.

One of the cool features of the Mission Planner is that you can load and save configuration files. So you can not only have different files for different aircraft, but also share them with others.

This is particularly handy for common airframes. Once someone…
