I was down visiting the area I grew up in, Aptos, CA this week and had a opportunity to get some footage of the world famous (infamous) Aptos Post Office Jump Course. Pros from around the world ride this course when they are in the area, but this time only some of the local bad a$$ kids were ripping up the course. And they were cool with me flying around, kicking up dust while filming them. About 80% of the footage was shot with my GH4 on a Tarot 810, TPpacks AG1000 gimbal and my Viacopter 8bit AM board running 2.3b5. After I ran out of batteries for it, I put up my phantom 2, H3-3D and Gopro Hero 3 Plus and got another flights worth of footage.

Another video using the Sony NEX 5N along with a TPpacks.com AG1kDD 3 axis gimbal, Lobster V2 Y-6 Copter and my Sony NEX 5N. I went real early out to AT&T park, home of the San Francisco Giants to film the stadium. The first two flights were in heavy fog and like 10-15mph winds with gusts in the 20's. But the sun came out and the fog lifted for the last two flights. Almost all of the footage was shot over water using the 18-55mm lens set at 25mm (50mm equivalent with the sensor crop) so even with the close shots, I was pretty far away.

I mounted a 2 axis, 3D printed brushless gimbal on my Skywalker 2013 and after doing a lot of balancing, I got it flying. I still have some other issues, mostly with my eagle tree stabilization behavior, but I'll work on those next time I fly it. The skywalker may not be the ideal platform for a nose mounted gimbal. Because of the prop wash hitting the tail and the large surface area on the side of the plane, I tend to have the nose wagging quite a bit, especially flying into wind or with a cross wind. That causes the yaw wobbles that you see in the footage. Otherwise, the gimbal behaved as well as I could have hoped and the plane flies fine with it. Although I love how much cargo I can lift with the skywalker, I'm going to start researching some of the larger FPV flying wings to see if the gimbal would work better on those. Basically I need a plane that flies really true.

And yep, I thought about going to 3 axis gimbal, but my 3 alexmos gimbal that are all 3 axis can only tilt 30-40 degrees before it starts to wig out. The 2 axis gimbals can tilt to almost 90 degrees without issue. It has something to do with the coding in the AM boards.

So here's the video:

This weekend we had perfect weather for the Spreckels Lake fleet day military regatta here in San Francisco. I got some aerial video of it with my TPpacks.com Y-6 Lobster copter and AG1KDD 3 axis brushless gimbal carrying a Sony NEX 5N with 18-55mm lens.

Well I got back from Yellowstone and Grand Teton a few days ago and finally got the aerial footage edited. This was all shot on my TPPacks.com Lobster V2 Y-6 copter (6s) with the AG1KDD 3 axis gimbal and Sony NEX 5N except for one shot over the deep valley was shot with my Shrimp Y-6 and a Gopro Hero 3. Most of the days I was flying the wind was over 20mph and some days were over 30mph So I did have to do some post stabilization in a few of the clips to get some of the jitters out, but there were almost zero big wobbles or movement from the gimbal, even in 30mph winds, which was pretty amazing.

A buddy of mine who does aerial video for the movie industry recently setup one of his large heli's with a red epic brushless sized gimbal. He's using iFlight 8017's and a Viacopter controller and 3rd axis board. The gimbal is huge and inside the ball he has a 4s 5000 pack for both the gimbal and as aux power to the camera. He had to spend many hours adding lead to it to balance as it's not adjustable, but it's incredibly wind tolerant being inside the carbon fiber ball.

I was shooting from my Askman/TPpacks AG1kDD gimbal and a sony NEX 5N along with the Viacopter board and FPVmodel 3rd axis board.

Yesterday I took some footage using my RCManChild 3D Printed 3 axis gopro gimbal and got the best footage yet. First off, the copter I am using is a TPPacks.com/Askman Shrimp Y-6 using DJI F550 motors and escs and a DJI Naza Lite Flight controller. I attached two 10mm tubes under the copter to act as rails to mount the gimbal as far forward as possible. When using a 2 axis brushless gimbal you only need the gimbal forward enough so the props aren't in the shot. But if you have the 3rd yaw axis and use follow mode on the alexmos controller, your going to get prop in your shot every time you yaw the copter and the camera rotates to smooth out the motion. My solution was to mount the gimbal almost between the front props of the Y-6 so that the gopro hero 3 black on 1080 60p medium can pan about 60 degrees left or right and not see the props.

Youtube doesn't do justice to how smooth this was, most of the jiggles I had in the past due to the vibration isolation setups are gone now.

Today, I got my first few flights with my new TPpacks.com AG1kDD 3 axis brushless gimbal with my Viacopter AM board, the FPVmodel 3rd axis expansion board and a Sony NEX 5N and it all worked flawlessly. I flew it all on a Askman/TPpacks Lobster Y-6 copter on a 4s 9000mah pack. Previously I was using 2 AM boards to test out this setup, but I was always getting some jitters at certain angles of tilt, caused by a jitter feed back loop between the two IMU's. With one IMU on here, I can now tilt the copter 50-60 degrees without jitter. I setup a switch on my TX so I can switch between yaw Follow mode and yaw heading lock mode and that worked great. I would have to adjust the angles of the camera when switching from follow to heading lock, but it wasn't a big deal. Overall, I'm really happy with the results I'm getting with this setup.

Had a few fun flights get some video of my new Askman Shrimp Y-6 copter with a prototype RCManChild.com 3 axis gopro hero 3, 3D printed gimbal. It's being run by 2 alexmos gimbal controllers. My buddy Mike was flying his DJI S800 with a Zenmuse and Sony NEX 7N. I still have a bit of tweaking to do on the Shimp, mainly figuring out a way to move the gimbal further forward so that they lower props don't show up in the video when the yaw axis rotates.

Just for a fun project, I worked with my buddy Don (Dhdsracer) to make a 1 axis brushless gimbal for my new Skywalker 2013 FPV plane with the 1900mm wing. I'm using a Viacopter alexmos board alone with a 2212 brushless gimbal motor from RCManChild.com (mine is a prototype, they should be for sale soon). The gimbal is 3D printed and really nice and compact. Hopefully I'll get to show some photos of it soon, once it's nearing production.

This was not the best day to test out the gimbal as the winds were in the 10-15mph range with gusts that would probably higher. And adding the gimbal to the nose of my plane through off my CG a bit making it nose heavy. Next time I'll work on getting the flight pack further back.

The gimbal and the AM board worked pretty flawlessly, but being only roll axis, it didn't do anything to help the pitch, which with this wind, was another problem. Still, the wings were rocking around quite a bit and the camera is nice and level for most of the flight. Next I might go and try to make this 2 axis and see how it does.

Flying out to the ship I was 1.5 miles out.

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.

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.
