Gimbal mounts

[hoggyjay]

After a crash I lost a gimbal rubber mount and a retain rod. I ordered the following kit -

Yuneec Typhoon H CG03+ Camera / Gimbal Mount Set

The contents only have two of the retaining rods. Do I need a rod in every rubber damper? If not where do I position them, my guess is opposite corners.

Cheers.

 

[gwhuntoon]

You guessed correct. There are only two rods positioned diagonal from one another.

 

[hoggyjay]

Cheers.

Phew, My 'H' is an 'Amazon Warehouse Deal' return (bargain), and noting it had just the two gimbal mounting screws, I was worried...

If you don't crash into things you don't need any at all

 

[Nich666]

Hmmm, But what if the Typhoon crashes into something; Hic ????

Add some fishing line tied in a loop loosely through the rubber bushing mounts. Or some very small zip ties. Keeps things from spreading too far in event of a crash.

 

[Nich666]

A bon idee, I will try that, but I think PatR was worried about me crashing into things!!

Well...no one ever intends to crash.

Hi Ron, I like the Haunting reference, are you thinking of scaring everyone off?
I have called mine Phœnix, waiting for the inevitable.
But at least if it happens, I have a good selection of engines to strap on the front to get me out of the desert.

That belt and braces idea is a no-brainer and as soon as the weather breaks i'll be back in the air.
The RealSense you have is also a must, but the price over the pond is prohibitive. Rats.
Regards, Brian.

Brian, I now have 2 TH480 aircraft. This was the first one. My wife named it “Beetlejuice” with the hope that if it went AWOL we could say it’s name 3 times and it would appear.

I named my newer TH480 “Asimov” in honor of my life long favorite sci-fi author.

I got the RS on this one because as a beginner I didn’t know enough about RS and thought it would save me from stupid pilot errors. It can’t and didn’t. It’s only useful for 2 flight modes that I’ve not used but a couple times in over a year. The down facing sonar on the RS module will save you from landing with gear up though and that could be a boon for beginners.

rdonson,

Might it be possible to remove the zip ties you are using and employ some that are smaller in width and cinched a bit looser? My thoughts are what you have are on there a little tight and likely impacting gimbal performance. They sell some very thing ones at hardware stores about 4" long that work pretty well.

 

[rdonson]

Good thoughts and thanks for commenting, PatR.

On my choice of cable ties: my wife had exhausted my supply of slightly thinner black ties prior to my installing these. My replacement order of cable ties were delayed and so I went ahead with these. @Steve Carr suggested black ties as they are more resistant to UV deterioration.

These are what I was waiting on and they arrived about a week after my mod:

They would have been ideal and if I feel the need, I will replace the ones in the photo with these.

I believe I thoroughly tested these ties and was looking closely to see if they restricted the movement of the dampers. I tightened them up a bit at a time until I was happy with the results. If you look close there are two things I did to improve how they work. First, I crimped the cable ties at the top with needle nose pliers so what passed through the dampers were more of a straight vertical line. Second, there is a bit slack at the bottom.

After a few dozen flights with both of my TH480s set up this way I've seen nothing in the 4K videos that causes me any alarm.

P.S. I did try some 4" ties but they didn't work well for me. A 5.5" or 6" tie made the task a lot easier and excess nylon is easily clipped.

 

[PatR]

My error on the 4” length. There are some 8” ties out there the same width as 4”. I had forgot those were what I first used. I use Dacron fishing line now.

 

[rdonson]

OK, no problem. Just curious, do you think dacron fishing line is a better solution? What weight line would you recommend? I'm not a fisherman so I also have a question about tying fishing line for this kind of use.

 

[PatR]

Back in the day fishing for sharks was legal I used 80lb. Dacron and a 3’ wire leader so I had a lot of it stored in the shed. So that’s what I use. 80lb line in massive overkill . I would think anywhere from 25lb to 35lb would be more than adequate.

I like the Dacron line because it’s easier to set a knot than monofilament and weighs almost nothing.

 

[Nich666]

I wondered about tying fishing line and as I hadn't 'fished' since wearing short trousers with a home made bamboo rod in the cut (canal), it seems there are two options that doesn't include a hook ~



I think I will try learning the double surgeon's knot, then if I miss-catch the H I can sew myself up... Regards, Brian.

 

[PatR]

Too much work I just tie the two loose ends together in a simple double overhand knot. It’s plenty secure for this purpose.
