Advice?

[SpaceEnthusiast23]

I made my first plane. Here is the download: https://kerbalx.com/SpaceEnthusiast/Vulcan

Can anyone experienced please download it and tell me how to improve the stability, but not too stable. I am new to KSP and I am still learning.

What exactly do you mean by "improve"?  There can be lots of possible goals for aircraft (or indeed, any craft):  stability, fuel efficiency, maneuverability, high top speed, low landing speed, operational ceiling, etc.

So:  is there something specific about the aircraft that you don't like, or that you'd like to improve?

Also, general tip-- whenever you're posting questions about a specific craft, it's often helpful to provide a screenshot; makes things more convenient for people who may want to help you.  Yes, you've included some screenshots on your KerbalX page, which is great   ... just, perhaps worth saving folks a mouse click.

Sadly, only people with the same mods as you will be able to even open the file to look at the plane. (BD Armory, Airplane Plus, NKD -- maybe others.)

Ok I fixed it now. As for the pictures, I am on mobile right now, so I have to wait until I can go on a computer. I might be able to do it on mobile, but this thing is pretty slow.

Yeah, I know. I guess that's why many people like sharing stock crafts instead.

Nice plane, but I didn't download it because like bewing said, it has too many mods.

My current guess is that you have way too much wing area forwards and too much mass to the back, leading to a dynamically unstable craft that wants to flip out at the slightest opportunity. For stability, you will want to move mass forwards and wings backwards.

Granted, if you want to dogfight, you don't want it too stable; I think real-world fighter aircraft are generally speaking slightly dynamically unstable and require constant computerized input (fly-by-wire) to stay on a steady course.

You can compensate somewhat with control surfaces, but until you're more confident as a pilot, I'd stick to dynamically stable craft, where center of pressure* is behind center of mass.

*I think KSP in stock displays center of lift, which doesn't account for just drag of parts, and I'm pretty sure is an arbitrary distinction caused by KSP's stock aero model. Somebody who's played stock can correct me if I'm wrong.

No CoD in stock game and CoL only take in account lift listed in part description (CorrectCoL mod is a popular 'fixing', but still no CoD) 

Also, if I'm not mistaken, not because a arbitrary distinction of the aero model but a design decision (or flaw)  to not include it.

Alright, thanks for that. I think the last time I used stock aero was the Great Souposphere of 0.25. I made at least one asparagus staged pancake abomination back in those days.

Thanks everyone.

Yeah I don't want it too stable. I'll try what you said, because when I turn, it starts of fine, then FAR tells me Large AoA/sideslip, then I just flip all over the place. Sometimes I even get Kraken attacks.
