Here's the first real flight of the Yun-1 with my 3 axis mod. FPVmodel stated that they will be releasing a 3rd axis add on for the Yun-1 in the near future, but I didn't want to wait, so I did it myself. On the Yaw axis I have the "Follow" feature turned on, which the gimbal follows the nose of the copter, but is delayed so that it can smooth out the yaw axis. If the copter's nose "wags" on descents or from the wind, the yaw axis can correct for it giving very stable video in all axis. For the yaw axis I'm using a iFlight 3508 motor and a Viacopter Alexmos board. I also replaced the roll motor with another 3508 motor and 100g damper balls with 300g damper balls to stiffen up the vibration isolation. In calm winds and with smooth flying, I'm getting nearly perfect video now. The only time I get jitters are when I descended too fast (which I did thanks to some unknown Naza 3.12 firmware issue) or when I tried to fly later in the day in 25mph winds (which was still amazingly usable).

This was one for those epic mornings in San Francisco. It was Sunny, warm (at 7am) and maybe a 3mph breeze if that. They also shut down the Golden Gate Bridge shortly after I crossed over for the Amgen Tour of California bike race. I got some flying in before and after the racers went by, but I stopped to watch the event.

We had one of those perfect flying days a few days ago. Like 2-3mph winds, sunny and warm. I went up to the Stanford University giant radar dish to do a few laps around it with my Yun-1. The Yun-1 is mounted to a MF450 quadcopter and the camera is a GoPro Hero 3 Black.

This is my first video with the Askman and Tppacks.com AG 600 Brushless Hybrid Gimbal with my NEX 5N. This gimbal uses brushless motors and an Alexmos controller hooked up to belts and gears for a big increase in torque, while still being pretty dang fast. With the extra torque, balance isn't as critical and I was able to easily use my heavy HDMI video out cable dangling off the side.

Figured I would share my favorite Multirotor and Gimbal (including brushless gimbal) threads in no particular order.

Here's the video I shot this weekend for Kymera Body Boards. They are in the process of making an electric powered body board. Think electric jet ski that you lay down on and does 20mph. And it's light enough that it can be carried to the water by one person. The video was shot with my Askman Lobster, Ag 600 and Sony NEX 5N and my MF450, Beta Yun-1 and GoPro Hero 3 Black. Check it out.

I'm currently beta testing the soon to be released Yun-1 brushless gimbal made for GoPro sized cameras. These are the first few videos I have taken with it and I'm very pleased to say that it performs amazing. It will be available from FPVmodel.com after they finish making a few changes they are getting from the beta testers.

Here's the videos. For best viewing, watch them on the Youtube site in full 1080p.

This first video refuses to embed into RCgroups for some odd reason!!! But it's the best one! Click the link to watch it on youtube.

I was flying at one of our rogue local flying sites and some guys with motocross style dirt bikes showed up to do some riding. I got permission to film them with my TPPacks / Askman Lobster Y-6 copter, AG600 gimbal and Sony NEX 5N.

I have been messing around with this plane design for years and this is the 13 iteration. All of the rest have been built out of Blue Fan Fold foam, but this is the first one out of EPP. The hardest part of the whole build was trying to get 9mm EPP reinforced with enough carbon fiber to not warp, especially the wings. But the plans are solid and the plane flies great. If you guys are interested I can post the planes for it as well. I found that my Kinko's has a large scale black and white printer that can do 36"x unlimited (roll) and it cost about $10 to print the planes. It's much easier then printing them out on to 8.5x11 and taping the paper together. I then just hit the paper with Super 77 spray mount and place it on the EPP. Then I cut out along the lines of the paper and the EPP below it.

The foam wasn't cheap, but it has roughly $60 worth of carbon fiber it in. The rest of the parts are: Power 10 motor, Turnigy Plush 40A ESC, 2x HS-65HB, 2x HS-65MG, 12x3.8 Slowfly prop and 3s 2200 25c packs.

Some of the changes on this latest version came from the 3D Hobby Shop EPP Extra, like the control horn design and from Bmoney69's EPP foamy build ( http://www.rcgroups.com/forums/showthread.php?t=1373042 ). In two of the photos below I shot it with my 3DHS foamy for scale purposes.

Just finished uploading my latest video. This is not the most exciting flight, but I still love this view of the 70" Slick. The lighting was also really nice. Having the GoPro Hero Camera on the wing does really screw up the aerodynamics as I had to add 10 clicks of aileron trim and 3 clicks of both elevator and rudder to get it to fly straight. That in turn jacked up all of the knife edge mixes.

My favorite part of the video is the "blender" that I start at about 4:05 in the video. It really shows you how much force is put on the plane doing this maneuver. The camera has a pivot hinge that is tightened down with a thumb screw. I had that screw down as hard as I could and could barely move the hing with my hands. But the blender snapped the camera back like it was nothing. Pretty cool.

Make sure to select the 720P option when viewing the video.

I just uploaded a new video of my 3D Hobby Shop 87" Extra SHP with a mixture of on board video using a GoPro Hero HD camera and ground based video.

Make sure to turn on HD on vimeo and 720p on youtube to watch them in high def! They even look good full screen. The vimeo and youtube videos are the same, just watch them in the viewer you like best.

Twisted Hobbys Vector Review

www.TwistedHobbys.com


Introduction
3D foamies are a dime a dozen, you can throw a rock into your local hobby store and you’ll probably hit one. Just going by looks, it’s sometimes hard to tell a good design from a bad. But over the last few years, smaller companies have refined their designs, altered the materials used and come out with a good crop of light weight, excellent flying, durable planes. Picking the one that is right for you sometimes requires a bit of research. I hope this review will help.

The first thing you will notice is the Vector’s striking paint scheme. The rich use of paint gives solid coverage on the porous epp foam which is rare to see. But as an added bonus, it also helps stiffen the normally bendable foam with no loss of durability. I do want to point out that the final trim scheme on the Vector is going to change a bit from the prototype I am flying. The Vector is the perfect travel companion. At 31” wingspan and 6.7oz, it easily fits in most trunks, back seats or on top of the rest of your larger planes in the back of your SUV. Its light weight and EPP construction allowed the Vector to survive 11 ‘testing’ crashes with only a single broken prop to show for it. Its durability combined with its very good 3D abilities makes it a great 3D trainer or lunch time flyer.
