My remote winch works well so far.  The biggest problem is the part on the ATV draws current all the time and it has to be on a maintainer whenever it is stored.  I think the remote on/off only saves the battery on the fob, otherwise, how would the control box ever know the fob is on?
I don't think radio waves penetrate water easily.  The control box might need to be mounted high enough to stay dry when it's needed.
You didn't go into detail about the problems you had with the winches.  Mine has a little bit of a delayed reaction compared to the instant on/off/reverse of hard wired controls.  It can get confusing if the cable is loose enough to snag on the drum and try to wind up the wrong way instead of letting out slack.

I was looking at this and noticed some "typo" errors.
In the diagram, about the force on the Quadguard if you hit a branch of a small tree in one place, I made some mistakes.
The torque on the rack from lifting the ATV is half its weight times the distance to a mount and it is opposed by 2 x half the weight times the distance between mounts.  The distance is 14 inches so the torque shown is 5320 inch-pounds, not pounds.
At the top the torque should be inch pounds, not foot pounds. 
The dreaded purple pencil has been applied to the illustration above.
(Purple was once the color used to mark my tech drawings after the first corrections failed to make everything correct).

Wish I'd seen this before putting an HMT link in a welcome thread.
Glad I can ask a question though:  The photos look like some trails are single file.  Is there a lot of negotiating who waits and who passes on a typical trail, or do they have one-way preferred routes?
I'm asking because, basically I haven't been anywhere or done anything trail-wise.
HMT is far away now, in a few years I might move closer.

Welcome, MrFixit, from somebody who doesn't drop by often.
Before my CFMoto 400 I had an '87 Kawasaki Concours, luckily I didn't have any incidents I couldn't ride home from.
I had to search what HMT is, found this:
https://trailsheaven.com/about-the-trails/hatfield-mccoy-trails-are/
I'm 65 with near zero experience myself, and too far to make a day trip to the HMT area, but is it $50 per year for out-of-state riders? That is cheaper than 1 day riding at the ski resort near my property.

I put the boots on a while back, here's a new cropped-from-old pic I might have posted already.
Now I should mention that the wireless control module always listens for a remote fob connection. 
Hence the vehicle battery will go dead if you leave it as-is long enough after you park it.
I discovered that when spring came around.
My solution is to keep it on a solar trickle charge between active times.
An alternative might be a disconnect switch that might also prevent a stranger's fob from releasing the winch.
I expect today's wifi-type remotes make that rare or impossible but it is an HF product after all.
The winch has worked well a few times unloading and loading itself on the trailer.
I think I'll give it a workout soon when the warranty times out and the break-in requirement becomes less of an issue.
(I've had a stay-at-home summer for family reasons).

I attached it with crazy glue (cyano-acrylate adhesive if I remember right).
No problems yet.

I'm confident it would handle smaller branches that would put maybe 20 pounds of force on it.
It isn't expected to be more than a single-use protection if I read everything right.
The manufacturer's videos show some distortion after a roll-over and they say it may be returned for inspection to see if it is still up to original usefulness.  That has to be considered in the light of having mandatory safety equipment in NZ.
I don't ever want to need it, like the air bags in a car.
I'm also thinking I'd like to see some evidence if somebody rolls my ATV when I'm not around.
That said, I estimate that a front-to-back force of 177 pounds will equal the stress of lifting both rear wheels by grabbing the back of the rack.
The QuadGuard is hollow molded similar to a $20 gas can except it is different plastic designed to be much thicker and stronger at the base while being thinner and flexible at the top. In the videos it wiggles from its own weight.  It has a welded seam just like my garden tool caddy I made from a gas can that started to leak, don't be shocked by how it is constructed.  I expect the cost of it will come down over time just like pocket calculators and cell phones did.  You'll need to make your own decision about what design meets your needs.  My purchase decision is based on a liability kind of thinking, like what will limit injuries if any, keeping a visible reminder that things can go wrong, and me having a counterpoint if my wife says I'm doing something too risky (old age etc considered).

You may have seen in another thread that I'm planning to use my ATV in challenging terrain.
The picture is halfway up looking down at the mild part of the hill.  It has similar topography & trees on top but it gets steep in between.
So I bought a crush protection device, a QuadGuard from New Zealand.  There were shipping issues but I eventually got it with no extra charges.
It attaches to the rear rack and as a strength check I grabbed that rack the way people pick up fallen cruiser bikes, hands behind my back and lifting with my legs.  My doc said I can't lift heavy things any more so that's pushing the limit but it saved me a lot of time figuring out another way to test the rack.  I managed to lift both rear wheels off the ground without any change to the rack at all.
The rack is attached to the frame in 4 places and once to each rear fender.  It's not massive but like I said, nothing changed lifting the ATV by the outsides of the rack.  The QuadGuard retaining bars fit well in places that are "indeterminate" as far as force distribution goes but again, it passed the lifting test.
I did a few things to my brand-new QuadGuard that may have voided the warranty but I thought necessary for mosquito control and to avoid stinging insect occupation in advance.  I drilled 1/8" weep holes in the 4 bottom corners to let water out.  They are #1 and #2 in the picture.  The 2 big holes would let most water out but some could stay if the ATV were on an incline.  Mosquitoes only need a little water to breed.  At #3 and #4 I covered the holes and top opening with some plastic bug screen held by all-purpose pvc/abs adhesive.  I haven't tested how strong the bond is but it feels good.  I've tried taping the screen to things but it is made of plastic that just doesn't stick to tape.
The QuadQuard attaches with 2 bars, 4 bolts, and hook-shaped clamps that fit over the CForce 400's rack bars.  The square bars are almost the same dimension across corners as the round bars are in diameter.  The torgue specified is 7 Nt-M or 62 Inch-pounds, about 5 foot-pounds.  It is not a lot of torque but it squishes the bottom of the QuadQuard until the bolts reach the bars, then it reaches full torque quickly.
The ATV looks good front & rear.  My way getting on & off is unaffected.

Nothing installed yet on my ATV. The extra time gave me a chance to think on this a bit.
The topic might have been better as "ATV crush protection" but I didn't know the term when I started.
I think there's another design that nobody made yet.  That would be a rack bag with its sides made of inflatable air mattress stuff.  I mean like the old boy scout sleeping bag type that had long tubes of heavy duty rubber boat material. With the rack bag empty or filled with soft stuff it could cushion the rider if they were trapped under the ATV, or allow it to keep rolling past the flat upside down point.
That's the whole of my thoughts at the moment.

Brief comments:  I used the 400 to tow a toy-ish wagon halfway up my hill carrying supplies to make a narrow trail/path.
Without room to turn the ATV around I backed down (without the wagon) each time, several times.
The Quadguard does block the view a little but not a lot and I could lean one way or the other to see around it.
I think I had my left hand on the rear rack most of the time and my right hand on the throttle-brake for good steady steering.
It didn't affect performance as far as I recall.

FYI I ordered one of the Quadguard urethane hoop type that mounts on the rear rack.  It's in the mail.  The price came out about $730 US including shipping.
After watching a bunch of youtube videos of the ATV-fail variety, I decided that the flagpole type might impale me during a forward roll-over.  I looked for a decent video cut from Starship Troopers to illustrate the unwanted circumstances but I am tired and I just gave up.  The point is that I personally would rather spend the extra $100 and have less risk.
I'll let you know how it looks when I get the chance.
Also what it weighs etc. since I don't know that yet.

As of yesterday, I think, the web showed me the specs & prices in the table below.
When I first found the quadbar or one like it, it was 2 bars and no spring IIRC.
I think now is a good time to get one, before I start my season.
But then I have to decide which one.  The quadbar wins on price & maybe ease of repair.  The airbag thing is definitely out, might go off during winching or something.  The urethane hoop might help if I got hit from behind like an accident I saw recently on Animal Planet Northwoods Law.  I didn't get to see how severe the guy's injuries were because I had to go to work, but he was sitting still in the middle of a road when a side by side hit his right flank.
Meanwhile gas (aka petrol) has been going up daily.  Prices and exchange rates are likely to change quickly too.

This story is famous to people my age in the USA, about an actor who was paralyzed by falling off a horse.

I don't think a ROPS is right for horses or bikers.  When I had my road bike I thought of having an air bag system like the one that the mars rover used to bounce its way to a safe landing.  But it was strictly fantasy for me.
I've been to my hill since starting this thread and for the first time I was thinking about the consequences of hitting my head on a rock while climbing the hill on foot.  No, before you ask, I don't want the government to make wear a helmet while walking up a hill.
What are they putting on the CFMoto ATVs?  I think the urethane arch is the best looking and seems easy to mount.  It bolts to the rear rack, though, and I'm not sure my stock rack will take the stresses.  It is rated for (pausing to look it up) 88 pounds.

Thanks for the advice.
The interview/endorsement for the ROPS is a farmer type of guy who didn't deliberately take chances.
Are there any Made In USA or other ATV ROPS options?
I was googling rollovers because I want to know what angle it could be parked at without rolling.
A video said an ATV with a rider is a stable as a double decker bus.
I bet it's because a newer rider expects the ATV to keep themselves upright, not the opposite.

Hello kids,
I am thinking about buying a "roll bar" thing for my C-Force 400.
I'm 65 years old and I intend to use it in challenging terrain.
The interweb search turned up 2 units in New Zealand and 1 in Australia.
I didn't see any from USA or Europe.
I am thinking about this one at https://www.quadguard.co.nz/
It costs about $750 give or take currency and shipping Can't say
It's flexible shape is supposed to wrap around your body until the ATV weight is supported elsewhere.
It is basically 1 piece of urethane or other rubber compound that springs back to shape, or almost back to shape.
They say to replace it if it is badly damaged in use.
So the potential is there to be out another $750, and another, and so on.
There is a less rigid, more effective version costing $1500.
That one seems to be fully resistant to damage and has adjustable tension, and replaceable covers.
The Australian model is made of steel tubes and I think it might break some sensitive  parts but the transition is smooth so far.     
Your experience & advice is welcome, can't promise to follow it.                                                                                                                                                                                           

My right front amber reflector lens fell off its black plastic backing.
I tried double sided outdoor mounting tape that does a great job on some things but I couldn't trim it well enough to get contact on the various surfaces behind the lens.
It may have fallen off by itself since I couldn't see any adhesive on it and it didn't snap in.
It's more likely the sides of my trailer bumped it and knocked it off while loading or unloading (yep it's that tight).
In any case I'd like it to look as good as new since the pieces aren't scratched or broken.
I might try black silicone RTV if I have any.
I have crazy glue somewhere.
I have duco cement (plastic model glue).
Elmer's and gorilla glue are available.
I'd appreciate hearing what works before experimenting.
Thanks In Advance,
-Jim
