An experiment of a crazy engineer was successful and now it scares everyone who sees this plane.*I tried so many things to make it more maneuverable but when the result was good the plane was very ugly so I decided to upload it in this variation. I've spent a lot of time making it and I hope you'll like it. Enjoy!*

@ProvingMars, yes, I understand, everyone has something to do. I won't be able to make planes for two weeks. I understand, thank you for all your help
I have not forgotten you. I just have a project on a short deadline. I need to finish it first.
@ProvingMars, yeah, I'll try something to make it maneuverable but I really spent a lot of time to solve the problem.
I have taken a second closer look at the Fire Raven. You are right, there is something more going on here. I am going to keep tinkering.
I did have some limited luck when I altered the thrust nozzle vector [using Fine Tuner], but nothing near controlled flight. Also, that is cheating the problem. I would rather find the cause.
Nothing like a challenge...
= )
@ProvingMars, it didn't work, I hope you'll help as I tried a lot of positions and variations
@ProvingMars, so I tried to change "fire raven" as you advised and it looked like COL and COT were on the line and COM was in 0.7 blocks away from COT
@ProvingMars, thanks for help and advice, I'll try to understand all you have written because I'm not so good in English and I understood only parts from your comment and I want to thank you again for helping me because I'm a bit new player and need help to build something truly interesting. Thanks for all your support!!!
Critique time. These are ment to be helpful comments.
thrust=5 ??? It is a small aircraft, so start small. Once it flies, add more power.
The CoM was way too far forward. Once I poked around a bit, I could see why. I know it would seem logical to put more mass forward to keep the nose down, but it doesn't really work that way. You want to keep the CoM forward of the CoL by 1/2 to 1 block for a build of this type and size. Setting the CoM farther forward makes the plane pitch up and down more slowly (sluggish) like a heavy bomber. Setting it nearer to *CoL makes it more agile, like a fighter (harder to handle). Best to keep it easy to fly, then shift the CoM after you have it flying well.
The pitch up of this aircraft is due to the point of thrust. It is too far below the wing, and too much thrust to boot. The CoL acts as a pivot point. Any push (thrust) that is not in line with it will cause it to turn. Your thrust ports are below the CoL, and pushing forward, so the wing pitches upward.
Can this be made to fly? YES* it can. Think of what you did with the engines and gas tanks (you really only need one of that type). Do the same with another set of thrust ports, but at win level.
It's a great looking build, but there's the devil in the details. Keep working at it.
Sorry this is so long.

@Milo1628xa,okay, I'll try to construct something more interesting.
@ProvingMars, thank you I'll try to work even better.
Nice!
u dont see many of these these days, keep up the good work
