@anwar sir,
Just noticed (with some amazement) that there is no board for RC Gliders!
Perhaps we could have one?

@devanesan andrews,
Starting this thread at your request...

Since you want to try histart for launching Gliders, I'm posting some guidelines to start with.
(Not guidelines for high performance, just a starting point)

1. The histart consists of a length of rubber/silicone tubing plus some string/twine.
2. You can start with string length of 3 times the rubber length at rest.
3. You can start initial launches with tension equal to 3 times the weight of your model.
4. You can start with extending the rubber to 1.5, 2 or 3 times its resting length.
5. So you need to find rubber/silicone that will have tension equal to 3 times your model weight, when stretched to three times its original length.

As there is a lot of info on the net, I'll be posting data only from my own trials...

Meanwhile let me try to interest some more members in this by attaching a few videos
(Please don't mind that the have earlier been posted on this forum a year or two back)

RCI members - Welcome to Gliders, Sailplane and HiStart...

Thank you iyer sir. I guess it ll help lot of people

Iyer sir

I have searching for the rubber tube for long time and I couldn't get it.

Please see this and let me know whether this can do the job sir..
I got 12mm rubber tube of 1m which expands up to 3m

I have nylon wire...

Check with a pharmacy - the tube used a a cuff for measuring Blood Pressure

Sanjay sir... But ll I able to get 10m???

Until you try you won't find out 

Through the pharmacy you can get the manufacturers name (will be printedon the product paclage), and contact them

Sure sanjay sir.. I ll try to find it...
Thank you sir

You can ask for Foleys catheter( Urinary catheter ) 12 0r 14 no. in any hospital pharmacy store.
It has two types one is latex and other is silicone.
Latex one has good strength and elasticity.

14 no has some 4mm of size. the higher the No, more is the diameter.

Thank you manoj sir... I ll try that...
