Suction mounts on a canopy

Is there any trick how to prevent suction mount with a relative heavy gps
device on it (G96) to fall off the canopy every half an hour or so?!
The canopy is new, surface is perfectly clean, almost flat (blanik's canopy
starboard side), tried two diferent suction mounts, one with light PDA
device mounted but the result is the same - it is always falling off the
canopy!

A small amount of spit for a seal and do it while the air is at low pressure
eg while as high up as possible.

I was using very effective suckers with a locking action - until the
dangers of cracking canopies was pointed out.

Hi,

Have you tried the RAM-B-224 suction cup mounts that I sell? They work
great for me and I've sold hundreds of them to glider pilots around the
world. If you clean the canopy and wet the suction cup it should never fall
off. I use mine to hold an iPAQ hx4700 with large battery and CF GPS with
no problems. It has withstood the 4Gs of a loop and the bumps of a landing
on a grass runway in a Ventus with no shock absorber and the tire pumped up
to a high pressure - very bumpy.

It should hold your large Garmin fine as well.

If you have tried that suction cup without success then you may have
received a defective one that could be replaced free of charge.

You can see details he

Hi Clinton,

Good point! I sell a suction cup from RAM called a RAP-224-1 that pulls a
hard vacuum when you rotate the locking ring. I don't recommend it for use
on glider canopies because it pulls the canopy out of shape - which could
cause crazing or other damage in the long run. I would never use one on a
glider canopy, but it works well on glass windows in cars.

Just to reinforce what Paul says, I bought that suction cup mount from
him. It holds my Axim just fine. It never comes off. I hate to say
this, but I usually lick around the edge, then stick it on. But I
have to remember to clean the inside of the canopy _really_ well, or
my partner gives me such a ration of s**t that I can hardly stand it.
"There's no reason to ever touch the canopy." Well, sometimes, ya
gotta.

In my truck, I use the same Axim for navigation, and there I have a
smaller suction cup with a toggle lever on it that holds for weeks at
a time, but eventually falls off. Paul's suction cup is much better.

Well, not if you fly ASW 15. I have to touch it after each landing... no
way to get out without touching. ;(

Has anyone ever seen a canopy cracked by a 'lever-action' suction
device? You've got me worried now ..........

I read somewhere that water will work better than spit, and my own
experience reinforces this. I can't explain why, but try water
instead of spit. Fred

Hi Bernie,

I doubt it would crack a canopy. My fear (founded or unfounded) is that the
localized deformation of the canopy would lead to internal crazing -
especially in extremely hot or cold conditions.

I just wouldn't want to risk a $2000 to $5000 glider canopy.
