I have been scratching my head about how to mount my Metal Helicopters safely for several years. I have heard of people using plastic wine glasses. I have not seen anything like what I thought they should look like until I saw some cheap party glasses. The glasses have separate bases which I left off and fitted a cut down rivet into the top which fits nicely into the screw hole of the Cobra I am using. I will drill similar sized holes in the other metal and plastic Helos I have.
Of course these will do for landing Helos so I will need something a bit taller for higher flying aircraft as these are no higher than my trees. Somewhere in my spare room are some TV aerials which I want to try and fit to a glass.
