Nobody has a problem until they have a problem...
that pretty much sums my view up. it has happened to some, and if a $2 strap will keep it from happening to me i think i'll strap em' down. always have always will. tugging on it everytime you preflight will eventually cause it to seperate. with no strap i hope there's a video.

fly it like you stole it

I've never liked using velcro on the gyro with nitro helis because it can be transmissive of vibration from hammer blows with heavy cyclic inputs. My preference is an elastic band. In preflight, it's obvious if oil ingress is underminding the pads stickyness.
It also depends on what gyro you are using in that gyros like the 720 can require a great deal of tuning in the pad setup will the likes of the 611 are more forgiving.
There is also the rubber sleeve thingy which I can't remember the name of right now. This makes for an excellent retainer.

No need to tug on it, just look at it. Maybe it's just the fact that nitro/oil is eating it up/effecting the glue for you nitro guys.

On my Trex 600 nitro im running a JR G770 3D which is VERY sensitive to vibration/setup and have zero issues with velcro .I was thinking about a elastic band but they seem to dry-rot and put more stress on the gyro and the elastic will hold the gyro tighter which allows more vibration.Velcro seems the safest way to go but I guess its different strokes for different folks,just giving my advice on the subject .

Sorry but this is almost funny.
My argument is this. Suppose you have the strap, and it's on, and it does it's job. The tape fails, but the strap holds it on. Because it's still on there and nothing seems out of the ordinary, you just keep flying. Sooner or later it's just going to fall out anyway.

imho, you're better off just checking it on the preflight.
Now, even with the gyro strapped I do a pre-flight check.
Then what good does that strap really do? If you make sure it's stuck to the tape good on the pre-flight, it's not going to fall off anyhow.

If it gives you a little peace of mind, then sure, do whatever makes you happy.

Ultimately my point was that you're better off just doing a preflight. If you already are, then you've nothing to worry about.
Its best to have a strap and also do the pre flight.

Rotormonkey- your somewhat true, First of all, if it comes loose with the velcro strap there will be plenty of symptoms and warnings, Unless your running the strap way to tight.

If you run the strap AND preflight test it everytime you will catch it comeing loose without disaster, If you run without the strap and still preflight then it can still come off in flight.

I dont look at it as peace of mind, I look at it as useing your head or not useing your head.

EDIT-
If you run the strap AND preflight test it everytime you will catch it comeing loose without disaster, If you run without the strap and still preflight then it can still come off in flight.
I kind of said that wrong. What I meant to say is --

If you run the strap and still preflight the tape everytime then if it fails in flight youe will still catch the problem before you lose your gyro (because the strap did its job), however if you just preflight without the strap then sooner or later it will come off in flight and will end in disaster.

No need to tug on it, just look at it.
if a pad is dried out and about to let loose, i don't think you could always tell by looking at it. hot and cold, oil, vibration, all things that can go on in a flight could finish a pad off easily in 6 or 7 min. looking at it doesn't give me any comfort. different stroke i agree. i like not worrying about it. my thumbs shake enough somedays already.

Y'all might be right. Personally I've never used the strap, and haven't found a need to yet (knock on wood). If the pad is holding well you can give it quite the tug, and it won't come off. When you're TRYING to take it off, you can practically lift a 50 size glow heli by the gyro alone.

Anyway, my point was you're better off with a preflight check than just RELYING on the strap alone. If you do both then fine, but just strapping it on and forgetting about it is likely to bite you in the arse eventually.

Not saying you shouldn't do it, just I don't.

If it can't hover, it ain't worth flying.

As I mentioned on my first post, my 600e's gyro fell off at home (lucky me). I had checked it before my last flight of the previous day...

It sounds like some might not be cleaning or making sure the application area is level.

I never flew with a gyro strap until recently. While doing some hover test in the backyard on a Raptor50 the 401 fell off to one side. The mounting area was prepped clean and dry but the Rappy has a gap in the frame under where the tape mounts so nitro apparently worked its way in from the bottom until the tape failed. I sealed that area with a little clear silicone prior to placing my new 520 there. I also noticed my 401 about to let go on my 450 electric this week during a preflight. I now run a strap on it as well. The 450 has the 401 mounted under the boom block and I placed a small pc of the loop velcro on the gyro itself so when the strap rides over it ,it actually has something to hold to to keep the strap from sliding. That way the strap can be quite loose and still keep the gyro in place. On my Rappy I took a Q-tip and smeared a light coat of clear silicone around the base to cover the tape from the sides as there is not a convienent method of running a strap over the little 520.

Yeah, right! The same guy that does the "visual" inspection...

Nowt wrong with a strap

Have any of you guys looked on E-bay for double sided foam tape,from 1mm up to plus 4mm,ideal for gyros ect and cheap as chips for a 3 metre roll.I use the 1mm stuff that is used to retain automobile number plates and it works a treat.Double it up if need be and it really hangs on.
