Bungee Launcher

Step 8 Deployment

Place your anchor at the upwind end of your field. You always want to launch into the wind.

Make sure your anchor is firmly rooted in the ground. Give it a serious tug to make sure it won't pull free. If it does come loose when you're launching, you will have a dog stake projectile heading your way.

Take note of the above step. Failure to do so may result in a serious injury.

Connect one end of the tubing to the anchor and unreel it away from the anchor towards your take off postion. When you come to the end of the tubing, clip the fishing line onto it, and start unreeling the fishing line.

Once you have unreeled the fishing line, clip the parachute or kite tail to end.

If using a parachute, attach the lines end of the parachute to the fish line.

Hook the other chute ring to the tow hook of your glider, and start walking backwards. As the tension builds up, keep a firm grip on the plane. When you've reached the point where the tension is enough, it's time for launch.

Throw the glider forward and a bit upwards. When starting out, it's best if you have a helper be the one launching, so that you can have your hands on the radio, ready for the launch.

Remember to always launch your glider into the wind. If the wind shifts after you've un-spooled, don't be lazy and ignore the above advice: adjust the highstart so that you'll be launching into the wind. If you launch with a cross-wind, you'll be asking for trouble.
