FBW Testbed

Can you guys help me? This plane's FBW only works properly at IAS 500-600, lower than that and it flips out, higher than that and it wobbles.

Plus, I want to make one of those monitors like on the pigpen but idk how.

Also, is there a way to reduce the time between rocket launches?

    So i guess you are trying to build a plane that has reduced aerodynamic stability. This is very well possible in SimplePlanes. I for my part love building planes like this. This one for example.

    First of all i would recomend that you take your control logic out of the actuators and into the variables section to make modifying the code easier. Building a plane like this is quite fiddely and therefor it's easier if you don't have to search for your rotators each time you want to change something.

    If you do it like this it's also easier to split up the functionality into some variables. I for my part like to have one variable for each actuator in case of my plane from above this would be for example StabLeft and StabRight. Those two then have variables splitting into elevator and roll.

    Next you need to establish some sort of maximum value you don't want to exceed (you mentioned your plane freaking out) mainly for angle of attack because if you go over a specific maximum value for angle of attack your plane stalls or exceeds the maximum you can compensate witch your control surfaces and you loose control. In my example plane the closer the angle of attack gets to 95 the less authority will the pilots input have.

    You have several different ways to accomplish that. The first one is like you have seen in my example plane another one would be a PID-Controller.

    Keep fiddeling with it and don't hesitate to look at other peoples creations or read up on it online. As i said it is relatively difficult to get a plane like this flying consistently.

    Your second question was about these fancy displays. Those are made with labels and can be programmed using rich text. It's too takes a bit to wrap your head around but shouldm't be too hard.

    What you are looking for in your third question is firingDelay. If you like modifying the XML of your planes SimpleCheats is a great resource to check out the current knowledgebase of what's possible in the game.
