Flight physics

Created by Rothary

This microchip more or less simulates simple flight. Simply slap this onto a grid and connect control inputs to it. All velocity based forces are tickrate compensated, ie they work the same at any tickrate. This microchip "simulates": - Lift - Vertical and horizontal aerodynamic stabilization - Induced drag - Counter roll torque (wings resisting rolling motion) - Propwash - Propeller thrust IMPORTANT NOTES / INSTRUCTIONS: - The chip contains lots of variables inside that you can adjust to change or finetune the behaviour. - The chip contains control inputs, including propwash, control surfaces and flaps. Only connect the ones you want to use, the rest will have no effect. Undercarriage and open canopy only affect drag. - Control inputs (apart from ailerons) are for simplicity's sake calculated as rotating the entire vertical or horizontal stabilizer, so you may want to keep their control angles lower than you would for separate rudder or elevators. - If you want the controls to be gradual instead of instant, you'll have to add your own logic for handling that. - Grid mass scale affects its flight behaviour. You can try tinkering with that to see what effect it has. - This chip does not simulate having a physical tail or wings that get pushed up or down by the control surfaces. For the sake of simplicity, the controls simply add rotational velocity to the entire grid. This means that even if your tail is touching the ground, pulling up can still make the nose lift up. - If the stabilization seems to be for the wrong axis, simply rotating the microchip seems to sometimes be enough. If not, you can also just rotate the entire build on its axis by for example placing a brick on it, selecting everything except that one brick, cutting, rotating and pasting.
