06 Envelope

Back to overview: Tutorial i4

It does not matter if you have a transparent or silver envelope. You can handle both the same way. Before you fill them with lifting gas, test them once with air, to train everything. Once you use helium it´s one stepp trickier since the balloon likes to fly away all the time.

To seal the envelope, use one of the clips, like shown in the picture. Fold the tube vent several times, to make sure no lifting gas will leak. You can use your wet lips to check if lifting gas is leaking, it will feel cold.

Set up your silent_runner as shown in the pictures. To connect the parts to the envelope you use TESA sticky tape. Fold one end of each tape, to later remove it easily. If you remove the sticky tape, do it with some care, to not rip the envelope. You can freely move the motor gondula and battery to front and back, depending on the position of your payload, to level the airship. Use some little ballast thins (coins, lead, etc.) to fine tune the balance of your airship. If the airship is filled with lifting gas, make sure your balance it a little heavy (1-2 gram). This way it will come down on it´s own if something goes wrong.

Make sure you are prepared to answer a lot of question to all people around, since now you are one of the very few people in the world who have a flying racing airship. Be prepared, now the flying starts: 07 Flight
