Monto RC Hobby **Avroto** Motors Contest Giveaway!! Beyond the hover!
Get over to http://www.multirotorforums.com and join in the competition
http://www.multirotorforums.com/showthread.php?666-Monto-RC-Hobby-**Avroto**-Motors-Contest-Giveaway!!-Beyond-the-hover!
Up for grabs
SIX (6) M2814-11S short shaft 770kv brushless motors by Avrotor – kindly provided by Monto RCContest Details
To win though, you’ll have to fly like you’ve never flown before……………beyond the hover!
The contest is simple, fly as many laps as possible between a table and a point on the ground fifteen feet away. The winner will be chosen randomly from the top five entries as voted on by the multirotorforums.com membership!
The rules are simple but in applying the rules you are encouraged to be as original as possible. So long as you meet the spirit of the rules you will be eligible to win. You are encouraged to be creative both in flying style and in what you fly and the membership will vote for the videos based on overall appeal of your submission. Video quality will not be judged though so don’t burn up a lot of time editing and polishing your recording.
RULES:
The table has to be at least 30 inches above the ground. It has to have a continuous flat surface (no holes to reduce ground effect), a defined edge all the way around, and cannot be modified to facilitate landings or take-offs.
The point on the ground has to be at least 15 feet away from the edge of the table.
The time will start when the multi-rotor lifts off from the table for the first lap and will expire two minutes later.
Entries must be submitted to this thread via recorded video between Friday, July 15, 2011 and Friday, August 19, 2011
There must be an obvious attempt to fly laps between the table and the spot on the ground.While it won’t help your chances of winning, you will earn the respect of millions of multi-rotor pilots across the world by posting crash footage

Droidworx releases the new CX series
The CX series craft is our multi task machine
suitable for anything from extreme sports
filming and making home movies to more
serious applications such as search and rescue,
fire spotting, inspecting power lines and bridges
and also surveillance, both indoor and outdoor.With optional removable propeller shields
(not shown here) the craft are safer when
flown nearer to people*. They can also be flown
indoors which is particularly important when
used for survivor searches in damaged buildings
and internal spaces. It also means that the craft
can be flown very near to objects such as bridges
and sides of buildings or power lines without any
concern of “tip striking” which would normally
bring the craft down and/or damage property.The fully enclosed canopy also allows the craft
to be flown in light rain and snow, the under
belly has slotted area’s for airflow and cooling.
The forward camera mount is 180 tilt allowing it
to look vertically down as well as up.expected release date: July 30.

Best Position Hold ever ?
A very impressive video from Bill Nesbitt http://diydrones.com/profiles/blogs/autoquad-ver-5 on his autoquad controller.
Watch the video, and see just how well this FC works !

“Everglades FPV Video” from RCExplorer
A beautifull video by David (aka “RcExplorer“) taken from several videos shot in Florida from his Tricopter
Ill let David explain the rest…..
It was such a cool place to fly FPV. My favorite flight was probably when I got to chase the airboat.I knew tigers were big but until you meet one face to face you can’t really imagine how massive and powerful they really are. Luckily this tiger was super well trained and were more like a big cat than a fierce killer.
The alligators really wanted to eat the Tricopter and jumped all over the place. I had to be really careful as not to get video of the digestion system of an alligator when flying around.
If someone told me a couple of years ago that I was going to fly a triangle of wood with a camera strapped to it, filming tigers and alligators, I would have laughed. I’m so glad that I had the luck to get to do this.

KKmulticopter.kr releases the new Flycam blackboard
Developed from the everpopular KKuk, minsoo has come up with a new design
Using the same footprint at the ever popular “blue board”, the new “black board” uses the ever popular atmega168
Whats changed is the replacement of the gyros with MEMS versions, increasing the number of motor/servo outputs from 6 to 12 , and a “debug port” which we can assume will be used for telemtry/settings using xbee or similar radios.
Configurations are plentifull, from the popular tri and quads, thru hex’s, Y6, Octo , X8 , and even a twin quad !
Suprisingly, it does not have onboard acelerometers for auto leveling….leaving that option to the addon flycam Naviboard http://www.kkmulticopter.kr/index.html?modea=vieweng&mc_selected=MultiCopter&sc_selected=KKMulticopter&sn=flycam_Navi&id_no=92

Open Pilot Explains PID tuning
http://www.openpilot.org/pid-tuning/
From James and David at Open Pilot
This video is more than you ever wanted about PID tuning for a multirotor. A brief overview of our control scheme is given, followed by a demonstration of tuning a quadcopter on a string and then in the air. Finally, for those interested, a set of simulations is presented to try and give an intuition about what the terms do to both attitude and rate control.
OpenPilot TV Episode 2: PID Tuning from OpenPilot on Vimeo.
he consequence of having various parameters too high is demonstrated in flight to help users identify tuning problems.
To simulate the code yourself, if you have Matlab and the Control Toolbox, get it from http://wiki.openpilot.org/display/Doc/Control+code+simulation. I also want to make it clear that the magnitude of those values are in no way generalizable between simulations and between aircrafts – just the trends are. There are also plenty of parameters I didn’t systematically vary (such as reaction speed of ESC). -
