How to make a highspeed ROTOR KITE

What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him

Thank you very much! Its a pleasure for me!

You are welcome! Thanks a lot too!

Dear David, I didn't design bycycle kites jet. But it may be possible to make such a kite with the system " 4 lines rings rotor kites" , a video of which is shown in youtube some years ago.

Many thanks!

Good luck my friend!

Hi my friend. Please try to alter the length of bridle lines. When the kite tends to come down to the right, than the bridle on the left side should be a little bit shorter. Roger
