Multirotor loops and rolls just got easier with OpenPilot
With the latest release of the OpenPilot software version 14.01 come two new features (among others) that when combined, make flipping and rolling a multirotor (MR) even easier. A new flight mode called "Rattitude" is a hybrid of the self levelling "Attitude" and the more aerobatic 'Rate' mode. In "Rattitude" mode as the control stick on the transmitter moves out from the centre, the flight mode of the craft changes from 100% Attitude through to 100% Rate with varying degree of mixture in between. The effect means that letting go of the sticks means the MR will return to self levelling (ie Attitude mode) but you can still throw it around as the control sticks move out from centre, you get the aerobatic response of Rate mode.
Normally you would have to flick a switch to go from Attitude to Rate. In Attitude mode, because it's always trying to self level, to maintain forward flight you have to constantly be holding the stick forward. It feels like you're fighting it to a degree for the whole flight. Also Attitude mode limits the maximum angle of pitch and roll so if you try to roll in Attitude mode, you'll roll to the angle defined as the maximum and not go any further around.
In Rate mode, it goes where you point it. If you roll to 45 degrees, the MR will attempt to hold that angle until you tell it otherwise. Rate mode can be intimidating for the novice pilot as the safety net of self levelling is removed and depending on the settings, Rate mode can fill quite 'slippery' if you're not used to it.
The other new feature in 14.01 is Cruise Control which from my limited reading of the topic attempts to maintain a steady altitude when the MR is turning or banking by slightly increasing the rpm to counter the slight decrease in lift). With Cruise Control comes a 'Max Angle' parameter that when set to 90 degrees, combined with Rattitude mode, means that as the MR rolls past 90 degrees, it automatically spins down the motors. That means the part of the roll when the MR is passing through the inverted (ie the props would normally be pulling it to the ground), the motors are automatically shut down which seems to make for a much tighter roll.
From personal experience I went from rolling and flipping with at least 10m height to doing the same at maybe head height. The first time I tried this combination it was quite weird to hear the motors shut down as it passed through the 90 degree vertical point but they came back up a few milliseconds later. Posts in the OpenPilot forum suggest that setting the Cruise Control Max Angle (CCMA) to 80 degrees and the degrees / second to 360 make for some nice smooth rolls.
The screenshots below show captures from the OPenPilot GCS software version 14.01 and the settings required to change to get this to work. I first tried it on my "beater" quad with a CC3D flight controller and liked it so much I put it on my "nice" quad with a Revo FC and Ov3rquad frame. The video below shows the results from these settings on both my CC3D and Revo controlled quads with CCMA set to 90 degrees and the Rate mode "Degrees / second" setting up at around 450-500.
The next thing I want to try is lowering the CCMA to 80 and deg/sec to 360 for the nice, "natural" roll and then go the other way to CCMA = 100 and deg/sec =720. Maybe with these settings I might get in a few double or triple rolls before hitting the ground.

Can I use WordPress with a shared hosting plan?
If you have a shared hosting plan, you can install and run WordPress on it. You can also use a static site generator, such as Jekyll, to create WordPress websites. You can also run WordPress from your home directory, which will require a separate install on your server. If you plan to run multiple sites from your home directory, you should first read the setup instructions for your hosting plan to see if this is compatible with your particular site. Back to Top Can I use WordPress with a VPS? Yes, but the default WordPress install will be hosted on your website's website root. Back to Top How do I install WordPress? First, make sure you have your WordPress installation set up in the correct location. For example, if you're using a static IP address, enter that as the website root. Then, download WordPress for your operating system and put it in a folder called "WordPress" in your site root.
APM Arducopter: Problem with Altitude Hold Solved
The problem:
As soon as I engage Altitude hold on my Arducopter Hexacopter, it shoots up instead of holding a nice steady altitude as expected.
The solution:
My throttle mid-point was not exactly at centre and when I engaged Altitude hold, the throttle stick becomes an altitude adjustment control as opposed to a throttle meaning relative to the centre position, if the stick is up, the Hex will rise. If the stick is below centre, it will fall. I analysed a logfile where I had been hovering in a nice stable position and found my throttle setting to be about 480. I thought this would have been close enough to the default (500) but apparently not because after adjusting THR_MID, the Hex hovered perfectly in position.
These URLs helped me identify and solve the problem:
ReadyMadeRC Polarising Filter on a GoPro3 Black
A real quick look at the effect of using the readymaderc polarising lens protector on a GoPro 3 Black. The filter seems to help balance out the bright light coming from the window with the shadows of the surrounding office. The sky colour also looks a more natural blue.

2.1mm F:2.0 Turnigy Micro FPV Camera Lens
This image shows the view from the default lens that comes with the 1/3-inch SONY CCD Video Camera (PAL) on the left and from the same camera but with the lens swapped for a 2.1mm F:2.0 Turnigy Micro FPV Camera Lens. On the right I've drawn a green box to show the area of the original lens overlaid on the view from the replacement lens. The original lens has quite a smaller Field of View in comparison.
While the new lens has a much wider FOV, objects appear smaller overall. Compare the size of the fridge in the middle of the frame. I'm going to try the wider FOV lens for now as it should be better in tight spaces.

How To Improve SEO With WordPress?
Making the switch to WordPress will make your site more visible to visitors and users, not to mention that it will make your site more functional and user friendly.
Of course, as a new site owner, you need to make sure that you don't do anything silly with your site. Here are a few tips on how you can improve WordPress SEO and improve the user experience on your site, just be sure to also find further information on the
Victorious website.
Use a good anchor text
The above image illustrates exactly what a bad anchor text is. It includes all the words that make up your keyword, but none of them are what you want on your page.
The trick is to use a better keyword and include a title and meta description that improve the relevancy of your content for the visitors that you attract.
Test your meta description
If your article includes more than a few words, you may want to test your meta description with Google. Some websites have been able to increase their rankings simply by testing their meta description.
Make use of SEO Metatags
If you write many new posts that add important information to an existing post, you may want to create a meta tag on those posts. This way, you can crawl your new posts and then display them in a more relevant manner by using a meta tag in your old posts.
WordPress makes this really easy, and it would be best if you do it right the first time. To add a meta tag, go to the "Manage Content" tab and then click the "Add New Metatags" button. You'll see that you have the option to search for existing tags, or start from scratch.
Hemp Proteins
Hemp protein is a powder made from the seeds of the hemp plant. Hemp has numerous benefits. It is very anti-inflammatory, full of vitamins, antioxidants, and omega-3 fatty acids. It's also extremely high in protein. Hemp protein is made into snacks, shakes, and even protein bars. Most Protein powders also have high amounts of omega-3 fatty acids, minerals, amino acids, and a wide variety of vitamins, minerals and antioxidants. In addition, they also contain fiber, phytochemicals, vitamins, antioxidants, and beta-carotene. Hemp protein is another fantastic source of omega-3 fatty acids, and you can find hemp products like oil or capsules to complement your nutrition needs, you can also get 30% off now with coupon code ADVANTAGE. This is important because there are studies showing a connection between omega-3 fatty acids and an increased risk of heart disease. A diet rich in fish or extra-virgin olive oil, both of which are high in omega-3 fatty acids, can reduce your risk of heart disease. Since hemp protein is high in omega-3 fatty acids, it's also a great source of the important, long-chain omega-3 fatty acids EPA and DHA. As a result, it's an excellent, cheap source of these beneficial fats.
Can Hemp Protein be Used as an Alternative to Milk?
With all of the positive health effects that are associated with hemp protein, it's no wonder that a number of manufacturers are now incorporating hemp protein into their products. What's more, hemp protein products are available in a variety of forms. Hemp protein powder can be made into a delicious snack, shake, or bars and can even be made into delicious hot chocolate or ice cream. Another exciting development is that hemp protein supplements are becoming easier and easier to find. This is largely because of the growing political resistance to federal farm subsidies in the U.S. This lack of support has forced many companies to look for new ways to make money without government subsidies. Many companies now offer hemp protein products on their own websites, offering hemp protein powders that are fortified with a combination of vitamins, minerals, and fatty acids. They're also a great source of omega-3 fatty acids. Companies have also developed special hemp protein powder bars and healthy-food-beverage products made from hemp flour. Both of these products are made to provide the nutritional benefits of hemp protein powder but with the convenience of a cookie, a shake, or a bar. You can use these products as alternatives to the products that come in packages, or you can try to eat them on their own. These are both great options for getting the nutrition you need without sacrificing quality. In other words, you can eat more of the delicious foods that come in bags, but you can also make them from scratch at home and enjoy them on their own terms.
How Can You Get More Hemp Protein?
Hemp protein has not gained acceptance by the food industry at the same pace as other protein sources. Because it's such a versatile food, there are a variety of options for obtaining a larger quantity of hemp protein. These include soaking, sprouting, and grinding your own hemp seeds. These methods have many advantages over just eating your seeds. These methods also eliminate the hassle of buying bags of hemp protein powder. Another option is to make your own hemp protein bars.
