I made a harrier, it looks quite like the real one but however it doesn't fly like the real one.
The CoM is directly at the same position (almost, not perfectly but I can say that its good enough.
I can't make it take off vertically but its possible for it to get its nozzle to about 60 or 70 degs and make a Short take off.
The max ark for the nozzles are 98.5deg, just like the real one, but when It flips very easily when the nozzle is pointing down more than 80degs
Are there any simple ways to make a stable VTOL aircraft?
Hey I think I have a solution. SO if you install a gyroscope onto your plane, Increase it's stability and speed to max (or even mod it to go beyond that), I think you'll notice a large difference in stability and if that doesn't correct your yaw problem, I'd suggest add about 5-10% yaw power (or way more if you feel like it deserves it, however it can get unrealistic at about 50%~) and you can use your yaw while hovering to correct for drift or stop it before it gets to be too much. Hope that helps.
I have a idea xml mod the nozzles to auto correct I’m no expert in xml but I’m sure it could work
@brians1209 build a gigantic tail, then use xml to srink it down to normal size
gyroscope gang where you at
did you just call the harrier stable lmao
@F104Deathtrap One problem I have is that it sometimes enters a uncontrollable flat spin at low speeds. Are there any ways to fix this?
@brians1209 Sure thing. Congrats on your Harrier
Yes. lol. Gyros works like a charm with this. Thanks!
@F104Deathtrap Yeah you can activate it by speed and activation group. That what I normally do
btw the nozzle scaling is making them look weird when rotated
@ChrisChrisThePy I used to use them as autopilot back before mobile users had a built-in autopilot feature. The key is to be able to turn them on and off because they're really quite terrible for any kind of aggressive maneuvering.
@F104Deathtrap well you just need to dampen the output probably. You don't need gyros for VTOL but it helps. I used gyro on my harrier gunship and that turned out pretty well but most ppl have a hard time figuring it out
@ChrisChrisThePy The gyro was literally designed for making VTOL aircraft and preventing them from flipping over. The reason Brian is having all this trouble with VTOL is probably because he isn't using one
But if you want a short answer: You have to make four thrust points like the RL jet or you can actually use the VTOL engine and your nozzles which I recommend.
I could take a look at it I'm kinda a pro at flight model so I might be able to do something.
@F104Deathtrap yeah gyros F everything
Is there some reason no one is talking about using a gyro?
Air brakes will help slow it down. Funky Tree reverse thrust may help.
Nice! Harrier?
@brians1209 Yup, input.
@Gluck Aha. So the
(PitchAngle / 90)goes to the input of the nozzle? Or the min and max of the nozzle?if you're into funky trees, you could probably mess with the input for the nozzles.
For instance, you could add something that auto-adapts to pitch axis changes (PitchAngle / 90), keeping the nozzle stable and pointed towards the ground. This system could be bound to activator 1, and when you switch A1 off, they act as normal thrust nozzles.
idk how to actually do that, but it's certainly possible.
