This catapult is called the Torsion Catapult. The tutorial on how to make it is on my website and in my playlist for siege engines.

Thanks! People find my voice interesting and unusual, I have been told I should go into voice work or radio.

@zhzhzh5 for an object with very low drag 45 is bank, for high drag like a marshmellow 37.5 is what your aiming for

[hihiwatup]

did you eat the marshmallows after?

[Davidzapper]

By the way the distance want to shoot the hight you need to get ect. is adjusted by a combination of power and release angle, i would have liked to see a nice big arching shot with a heavy solid object not a balistic marsh mallow, what good is that to storm a castle with or may be yanks dont have any castle`s so who are they to show you how to lay down the gauntlet . LOL.

[Davidzapper]

OK Folk here it is in plain English (British).

The longer the arm the faster the tip should move but this longer arm places more weight on the motor end so now you need a bigger motor to overcome this. There is nothing to gain in changing the release angle when you have simply lost power to the shot by making the arm longer. (who many yanks in History have ever made medievil seige engines?) LOL.

[gophermediapro]

Lengthening the arm doesn't change the angle that it stops.

[zhzhzh5]

43º not 45º

[zhzhzh5]

actruly its not 45degreees its 43 degrees

and how do u typ the circle

[eternalbattle]

it must not be tight enough

[willssonglist]

yup, generally thats about right. There are some variables and typically a little under 45 degrees works better. But shooting for 45 is a good rule of thumb.
