If i may, what about using cling wrap? It sticks well to most of the surfaces and is also thin & light weight.

Worth trying, especially on glidiatorís type of models.
What to stick it with? Rubber solution?
Wish I had 3M 77 spray adhesive. Too expensive.

Yes lamination sheet comes in various thickness.
I have a roll that is about 8 microns thick. Have used it on my indoor capacitor powered model. Worked pretty well as I was not aiming to keep weight down. A youngster from Nagpur whom I have been mentoring on indoor free flight used the lamination painstakingly peeled off from the brown paper one uses to cover school books as he did not have access to mylar.
Have tried cling wrap. The problem with it is it tends to stretch as it has a lot of elasticity. So after fixing to wing if you apply pressure on some portion of the surface it will stretch and create a sag at that area. That thin grocery bag is the easiest to procure and suits the requirement. Even the die had indoor flyers on hippocket recommend this when mylar etc is not available and one is not in serious competition.
There is another firm - Sprayway India who have a aerosol spray glue SPRAY66 which is an all purpose spray glue and half the price of 3M. They have been concentrating on B2B business for the textile industry. I got a couple of can two years ago and still using it. Will ascertain retail availability now from their Bengaluru India office.

Spray 66 uses LPG as propellent so it will not create holes in the ozone layer as will other aerosols!!

To everyone working on indoor rubber freeflight, or thinking about it, I can assure you that this may be the most cerebral and challenging forms of aeromodelling. It requires great understanding of flight principles, skill, dedication and oodles of patience. Most of the "masters" of this esoteric form of flight are at the top of their academic and professional careers. I've been fortunate to attend some of the world class sessions including the World Championships at West Baden Indiana in 2018. I also coach the local middle school and high school kids here for the Science Olympiad rubber power freeflight contest. Will post some pics and videos if others are interested.

Hi ask
Great to hear from a fellow indoor FF enthusiast. Have been advocating this aspect of AEROMODELLING for almost half a decade now especially in our Aeromodelers Association of India group. This finally resulted in a first ever Indoor National event in May 2017. Was more an awareness campaign as I was the only serious contestantó so it was basically a lot of demos and talks on techniques, rubber usage techniques, torque meters, etc, etc.
Link of my demo at this event

I have been following the Indoor championships happening in your side of the globe and also the happenings in the Science Olympiad scene. Have been advocating that we should start something on similar lines here in India.
Lot of discussions on SO aspects on the Hippocketaeronautics forum.
I had even made a thrust bearing  suitable for SO weight rubber models using a the opening ring from an soda can.
Can see the discussions on this at this link
http://www.hippocketaeronautics.com/hpa_forum/index.php?topic=20755.0P

Check out some of my rubber powered flight videos on the Foldnation channel on YouTube.

Trying to get about a half a dozen serious indoor free flight enthusiasts so we can have a meaningful indoor event.
The mission to get indoor AEROMODELLING into the consciousness of the Aeromodellers  here continues.

Hi all,
On the topic of indoor free flight - those interested would be thrilled to know that the worlds largest geodesic dome in terms of height and diameter- that is absolute nirvana for any indoor enthusiast has been recently inaugurated at the Maharashtra Institute of Technology at Pune. Much much larger than the West Baden dome where the last FAI F1 D event was held.
A fellow Aeromodeller in Pune is pursuing the use of this venue for an indoor event.
Letís see where this goes.

KK,
Navy hangers also have good height but have girdersrunning across where you can get your model stuck.
A geodesic dome has no obstructions.So the model can actually hit the roof and nothing will happen.

Military fighter aircraft are pretty small compared to commercial planes which gave tail fins that reach considerable height off the ground. Their hangars are therefore much larger and have more height than navy or airforce aircraft hangars. Now the airforce has large transport aircraft but I donít know if they have hangars for them.
