As it turns out, the largest size they have is 140mm, and that happens to fit reasonably well.

Did I mention they were cheap? How does $2.99 each (2 domes) sound? You'll have to find some way to attach them, and I sure wouldn't trust them for crash protection, but it's a cheap umbrella that weighs just under 2 oz.

Here's a link to the page, with all the varieties on it. If anyone snags one of the Lady Gaga ornament costumes, please do NOT post pictures

This is the 140mm size from near the bottom of that page:

Cheap as long as you don't want to ship overseas, shipping is almost 10x the cost od the "domes".

Speaking about domes, I experimented a little this past weekend with a homemade vacuum plastic former. I bought a glass bowl from Walmart for $3 and made a mold that would fit Rusty's UAP1 plates and then made some domes.

I used various plastic types and thicknesses, but the plastic that seems to work the best is PETG at about 3/32" thickness. Those are the clear ones in the pictures. I need to do some more tweaking before I try a thicker PETG or a Lexan sheet. All in all, they didn't turn out too bad and they should be plenty strong for crash protection! I'm also going to try a hemisphere mold next.

I finally got my X8 completed using the UAP-1 , really happy with the versatility of the kit contents. I have fired up the motors but have not flown it yet or even lifted off the ground. Kind of scary after having only flown max size of a (VC 550) with 4 motors. This thing is a giant compared......

Frame: Rusty's UAP1
Format: X8 Octo
Size: 32" M to M
Booms: 5/8" carbon fiber
Landing Gear: Rusty's CM-2 with brass tubes for the skids ( they are light).
Cam Mount: Averticalview
Flight Controller: WooKong WK-M
Motors: 8 Avroto's
Props: Top( 12 x 3.8) Bottom(11 x 4.7)
ESC's: 8 Hobbywing Flyfun 30A
Power Distribution: homemade using Gaui 500 (4 into 1) 3.5mm bullet connectors and splitter plug for 2 lipo's
Dome Cover: Old turbo Ace x720 dome
Weight: 9.56 pounds with Nikon D7000 and no batteries

(Top deck(IMU MC RX) Next deck(Booms and wires) Next deck(8 ESC's) Next deck( single or duel batteries)

I wanted to keep a clean looking setup so I have everything tucked inside but plenty of openings to keep all running cool

Got a cat in the pic for scale....

Poor Man's Extended Landing Gear

I came into ownership of a very, very nice (albeit busted) camera gimbal from Photohigher - specifically the AV200 - by helping out some really nice guys with their MK setup.

A $920 camera gimbal is out of my league budget-wise, so I was pretty excited that after ordering the repair kit for pretty cheap, I had a fully working gimbal! Then I learned that the landing gear that accompanies the mount costs $330 (plus shipping).

I contacted Rusty about whether he had any landing gear large enough to host this monster, and then I made a thread to see if anyone had some good alternatives to a $330 landing gear, but no luck. Then, I drafted an idea for a modified, angled boom clamp and sought someone to manufacture it, to no avail.

Rusty suggested something that I had thought of too, which would be to simply use two boom clamps mounted to a piece of G10 with one of them at an angle. His post about this conversation is a few pages back in this thread.

I completed the mod last night and it is shown in the attached pictures.I used some spare aluminum 5/8" rods that I had bought to use for arms (which cost about $2 each). I cut them off using a dremel after I had them mounted.

If I were to do it again (and I will) I would suggest using two clamps on each motor arm rather than just one because if I try to hold this beast by one of the legs, the leg tends to rotate around the arm - along with the LED's.

The nice part is that I can provide as much or as little ground clearance for the camera as I wish. the bad part is that I can barely get this thing out the door! It is really huge and bulky and awkward to carry around! Ha ha! I changed it's name (you DO name your birds, right?) from MegaHexa to "The Flying Table" because it is now so large and level that I could easily eat lunch off of it.

I have not yet shot video, but I feel certain that the legs (which leave slightly more than 120-degrees in front of the camera clear) will stay out of the shot, unless I use a GoPro in wide mode!

Of course, this gear will not help much in a hard landing. But which gear will help?

I welcome any feedback, but mostly wanted to show how it can be done.

I can assume your post was directed to bendicks, since it appears we both posted at the same time. Now I wish to remove my post because my sloppy build looks embarrassing next to his!!

Nice build there, bendicks!

Cool, so if anyone needs domes, you know who to contact ...

What temp did you heat the PETG to? I've still got some sheets of that to try, but haven't really gotten around to it.

Always cool to see complete copter pictures I bet the copter could lift that cat...

The extended gear is an interesting idea. There are only a couple things that might be a problem. One is vibration since the legs are in the propwash. I don't know how much farther you could move them inward and still keep them out of the camera though.

The other problem may be splitting the pultruded carbon tubes. Pultruded tubes are strong and stiff until you twist them just a bit too hard. At that point they split, and you get to replace them. Even with only one block on each leg, you can probably get enough grip to split the arms in a crooked landing. With two blocks per leg, it would almost be guaranteed. Worst case, you might end up having to use those thick wall CF tubes ($$$ not pultruded).

Cheers,
Rusty

I had 12"x12" sheets of the PETG and heated the oven to 300deg F, and then let the sheet sag by about 1-1/2" before I took it out. Sometimes I got a fold in the plastic, so I need to understand why this is happening. I also didn't use any release agent, and the mold popped right out without issues.

I'll keep you informed of my progress!

Bendicks - I love your X8....very clean and BIG! I don't know about your cat, but I have to keep mine away from my Y6 since he seems to always want to chew on the props. I've got tiny teeth marks on some of my older props.....

Nice build there, bendicks!

I think yours is also looking pretty good, nice gimbal......mine would not look so clean if I had not tucked all the wires away......actually have too much wire. Kept the full length on the Avroto's.
