Helicopter herbicide spraying

[@eddydogleg]

Took me back to the early 80's working a helicopter portable drilling. Two days to rig out, 3 days move and rig up, and 2 days to drill the well. I do not miss the stink of half burnt jet fuel.

6S is amazing!

[@stevefox3763]

Airwolfs retirement years are not so glamorous :-D

[@bardenegri21]

Really cool, nice shots too. Wonder what his PID settings are

[@jeffbluejets2626]

Mate of mine worked on Canberra bombers . I asked if he'd been in choppers and he replied, Nooo...and if you saw how many times all those bits above your head changed direction every time the blades go around, you wouldn't get in one either .:)

[@haroldsmith45302]

Another interesting video, thank you. Did the support crew clip a grounding lead to the airframe before they refuelled the helicopter and pesticide pump (to avoid static-electricity sparks at the fuelling points)? I did not see them do that.

[@TheCas2406]

That was a water hose for the spraying system, so no grounding is needed. See 1:43 center bottom of the screen

[@haroldsmith45302]

TheCas2406 At 4:35, propulsion fuel is filled into the helicopter tank, and at 5:00, fuel for the pesticide sprayer pump is filled into its tank.

[@robharris1344]

Harold Smith No rubber!!!! Helicopter is grounding itself and in relation to fuelling, Hoses have a continuity line running through them to equalise static potential between Heli and Fuel pumping facility. Static electricity potential takes two minutes to equalise and since that is a hot stop, all that metal is moving creating a whole new supply of potential. It won’t be a switch load, so jetA1 on jet A1 will be smooth and if the flash point was reached accidentally, no grounding lead would make a difference.

[@briantownsend8]

cutting that spray on and off REALLY HIGH UP.

[@RobertShaverOfAustin]

I worked on helicopters during the Vietnam war. Yes, a lot is riding on all that stuff whirling around at high speed. I'd prefer a fixed wing aircraft every time. Agent Orange was a herbicide. I wouldn't want that sprayed on me.

[@tommuhlemanjr.3871]

My god, they’re killing buttercups... the horror of it all! Lol!

[@oldestnerd]

I'm surprised the downdraft from the helicopter blades doesn't mess up the spray and bring it back around the helicopter and crew.

[@tylerw1418]

John Nelson it actually does pretty good at laying it down. But you don’t want nozzles on or past the width of the rotors or the vortices will bring it back up and and send it all over the place.

[@chrisleech1565]

Have you had anyone complaining about not getting updates Chris? I had to re-subscribe I believe, and click on the bell. Now recently I have other channels that are not "monetizing" getting left in some kind of KZbin algorithmic limbo. This is maybe why you have only ~1200 views of this to date. Your archival material is quite valuable to the RC community. Best regards, C

[@iforce2d]

This is the first I've heard anyone say that about my channel, but I have seen a lot of complaints about those problems elsewhere. It does seem a little strange that the view count is only 3% of the subscriber count after a month, especially compared to other content-similar channels notably Tom Stanton who regularly gets a view count of around 30-60% of his subscribers within 24 hours of a video upload. Admittedly his videos are better presented (with no boring coding lectures) and he makes the thumbnail a bit more interesting I guess, but this is still a massive discrepancy considering the commonality of subscriber type. I can only assume KZbin promotes content differently based on various metrics. For example Tom's channel is not much more than a year old yet already has nearly four times the subs of my 10 year old channel - stats like that would likely score higher as a measure of what people want to see.

[@jo2lovid]

At 1:07 your camera lense had droplets on it. Does that mean your fruit trees are also being affected by over spray?

[@iforce2d]

I was inside my house, so those marks are on the window and much larger than the sprayer droplets, would be from something else....

[@flyingrotorphoto]

Pretty sweet Bell Textron 206-L3 Longranger.

[@gygaxthegoat2491]

Are they spraying Roundup/Knockdown etc? Nice footage Chris, but fuck that. Id be moving asap.

[@timothyroberts8347]

Whats the cost per acre to spray .? helicopter's are expensive to maintain

[@iforce2d]

Yeah probably quite expensive, I don't know. But the ground is too steep here to do it by tractor, there's hardly any flat ground anywhere.

[@kightremin]

Just wondering what would gorilla glue be used for in this operation

[@iforce2d]

Just my little joke. It's the spray concentrate

[@jacobkemp1183]

We built a pad for ILR on seemeds qurray road in pukekawa, above Hinemoa Cleanfill, he uses it quite a bit, was flying off it last week again

[@voltlog]

is it possible that he is spraying insecticide instead of herbicide? Doesn't make sense to me to spray herbicide everywhere.

[@iforce2d]

There is such a thing as selective herbicide. This one targets legume and broadleaf, in this case mainly the buttercup, but also thistle, dock, and to a lesser extent clover. The latter is not considered a weed, but killing some of it along with the others is apparently a tradeoff they are ok with.

[@voltlog]

okay, makes sense now.

[@landlifem5872]

It looks like MCPA to me. It's a selective broadleaf herbicide. Will mostly target thistles, capeweed , wild radish, that kind of stuff. Very good chemical to use to get a clean pasture.

[@iforce2d]

Yes, MCPA

[@brianminto5035]

R.I.P. those trees though.

[@noweare1]

That guy can sure handle a chopper.

[@Rimraz]

Nice looking Longbox.

[@blancsteve4819]

What will grow in that area now it has been nuked ?

[@iforce2d]

It's a selective broadleaf herbicide. Will mostly target thistles, capeweed , wild radish, that kind of stuff. Not exactly 'nuking'.

[@DoloresSalgado-f9i]

👍👍😎😎👌👌

[@srnunan4783]

Looks like a good paddock that could be ground sprayed for 10% of the cost. Why use an expensive heli for this?

[@iforce2d]

There is barely any flat ground here. If you want to try driving a tractor or four-wheeler around 40 degree slopes to cover 9km^2 then give the farmer a call, he would be thrilled not to pay for the heli. See if you can figure out good places to park the truck for refilling too. Good luck getting it done in 8 hours :)

[@paulsharpe3794]

I wonder if he's using mission planer or eyeballs!?

[@iforce2d]

They have some kind of GPS guide thing to keep him on the right tracks.

[@yokonunz]

Spraying on animals, nice :) Milk and meat will be very saucy

[@mistercohaagen]

Shhhh.. Bayer is god now... Heil Bayer. They're saving us from climate change with cancer, it's fine.

[@iforce2d]

"Rats treated orally with MCPA excreted nearly all of it during the first 24 hours after intake (90% in urine, 7% in faeces). In rabbits and cattle, it is excreted rapidly, largely unchanged. In humans, 50% of the total dose was detected in the urine within 48 hours." www.who.int/water_sanitation_health/dwq/chemicals/mcpa.pdf

High altitude spraying

[@DoRC]

0:07 aaaand youre sterile.

[@ganste8310]

Maybe that was maple syrup or honey 😂

[@confusedwolf7157]

well at least you not get mouldy huh?

[@electronic7979]

Good idea 👍

[@Peter_S_]

Not. www.sciencemag.org/news/2017/05/where-have-all-insects-gone

[@iforce2d]

herbicide, not pesticide....

[@Peter_S_]

Agent Orange is a herbicide, not pesticide.... CARCINOGENIC Glyphosate is a herbicide, not pesticide.... CARCINOGENIC The list is hundreds and hundreds of poison products long..... ....and just look at how many of them were banned after being used for years because they were sold as "safe" at the time.

[@iforce2d]

Peter S I wish people would take a few moments to think about what they are saying sometimes. Do you think the farmer is just a silly dum-dum would jeopardize his livelihood and risk ruining hundreds of hectares of land, or selling contaminated beef without looking into things a bit? I didn't even tell you what they are spraying ffs. It's not Agent Orange or glyphosate, that would be absolutely ludicrous. Just because something is classified as a herbicide doesn't mean it has all the same characteristics of everything else classified as a herbicide. Whales and mice are both mammals you know. So bringing up Agent Orange is irrelevant. They are spraying MCPA which has been in widespread use all over the world since the mid 1940s, long before A.O (1960s) and glyphosate (1970s). So you would think that with an extra 20 years to study and observe any health risks, something might have showed up. If you want to make a more serious attempt to understand things, this might be interesting: www.who.int/water_sanitation_health/dwq/chemicals/mcpa.pdf Note such salient points as: "In aqueous solution at pH 8.3, MCPA had a photolytic half-life of 20-24 days in sunlight. In rice paddy water in the dark, it was totally degraded by aquatic microorganisms in 13 days. ... Its half-life in soil was 15-50 days." ...and: "Rats treated orally with MCPA excreted nearly all of it during the first 24 hours after intake (90% in urine, 7% in faeces). In rabbits and cattle, it is excreted rapidly, largely unchanged. In humans, 50% of the total dose was detected in the urine within 48 hours." Note also the carcinogenicity section where no increase in tumors was observed in rats that were fed 500mg/kg bodyweight of this stuff at for two years. For an 80kg human like myself, that would be the equivalent of 40 grams per day! Let's compare that with the dose I would have actually received if I had been standing out side and got sprayed. Applying 2 liters per hectare (10,000 m^2) of 75% concentrate and assuming 1ml weighs approximately 1g, that would be about 0.00015g per square meter. Even if we generously say I got 3m^2 worth of it, and let's say I also breathed some in to humor those that say inhaling it is worse, let's double it to 6m^2 worth or 0.009 grams. And I would get that just once a year, if I'm standing right under the chopper.... sooo..... compared to the rats which showed no evidence of carcinogenic properties when consuming the bodyweight equivalent (for me) of 14kg per year ie. 15 million times even the generous assumption of my dose , I'm feeling ok about it :) If I had to guess, you are likely to jump on the "limited evidence" of carcinogenicity mentioned on page 3. If so it would be a good idea to also read the cited reference: monographs.iarc.fr/wp-content/uploads/2018/06/mono41.pdf This one contains page after page of study results showing no significant cancer related effects, even in people working directly with these chemicals daily like the guys in this video. However, they do fairly conclude that it can't be ruled out, and that's about it.

[@marc_frank]

looks fun

[@umersaddique8472]

sir can i have your email i need your help regarding my project

[@sakitotak1]

yes, can I have it too.. Bobby

[@Peter_S_]

MMMMmmmmmmmm....... Cancer..... Yum.

[@lasersbee]

Holly Crap... I wouldn't be under a helicopter spraying chemical without a Hazmat Suit...:EEK: I would think it would be less expensive to spray by airplane.

[@iforce2d]

The abundance of comments to this effect is quite puzzling to me... see my reply to Peter S under the conversation started by Elektronik Atölyem. They do use planes for this in some places, but a plane can't follow the hills as closely as well as helicopter. Plane seems to be better for the fertilizer pellets because they are less affected by wind, and each payload is much heavier.

[@lasersbee]

That makes sense to use a surgical method of getting the herbicide exactly where you want it in more difficult applications. Thanks for the reply.

[@mathieub3953]

Awsome, insect mass instinction filmed! Great!....NOT
