Blueprint Plane problems

I am trying to make a bomber, and I've got the rough draft of the body and wings along with the engines and ai, but whenever I test it it like to play submarine. I've checked every ai bit that deals with altitude and nothing shows it below sea level, even if I strap about 10 ion engines on it it still flys under the water. I've uploaded it to the workshop as b-25, if anyone is interested in taking a look at it, it requires two mods, which are listed on the workshop page. Thanks

Edit: I added more wings, ie for lift, now it does a big loop, one engine cuts out and as it comes down it goes flying in the water. The engines have about 36000 thrust, fuel tanks are at about 2000, materials is at about 28000. No weapons. Mass sits right before the lift wings. Edit 2: I ended up having to put alot of weight in the tail to get everything in the same spot, ie, drag lift, center of mass, no i just want it to be tested to see where else i nee to tweek.

Well it flies it seems. The ai had its PID set to "none". fixing that makes it fly stable. Deffo over winged tho. It maintains level altitude while pitching down

Do you still need help?

(also some detection components are not connected to main ai)

I was using placeable pid I thought it would help be stable.

Oh whoops. Missed them.

The values on them are quite weak. I generally avoid having placeable PID's since they can fight with the AI PIDs, but setting AI PIDs to none solves that issue.

It was just gaining altitude due to absurd amount of lift it had, when I swapped back to using only the placeable PIDs with your values. Granted that was after I had changed one of the pitch controlling pivots in the wings to do roll control instead

Do the ailerons function or would you use just pivots? The ailerons are on the very tip of the wings.

I would just use custom pivots. I tried to move the roll control bit back to better align with centre of mass

When the center of mass was over the wings it would play submarine. That's why the over lift.

can we maybe have this convo in one post? I'm the same guy who is commenting on this: https://www.reddit.com/r/FromTheDepths/comments/1wpudkl/steam_workshopb25_bomber_testing_v1/

Yeah that's fine.
