Yep, TP batteries are lowest tier stuff.
Get some quality batts! ^^
Check the link to the battery comparison thread that others have already kindly provided.
If you can get SMC, no need to look further.

Do what Evan says. It would seem to me that you have tried to set this plane up for "tailerons", since if the elevators are Y'd together (via the control box), BOTH should respond in the same direction. I would also suggest that you have not declared the proper wing type in your TX or in the gyro. Furthermore, the HobbyEagle A3 can't work for tailerons. The fact that speed is involved tells me something is not right with the gain settings. You need to figure out how the A3 works, what it can and can't do and why it does what it does and how to test it before trying to fly the plane. Take out the gyro and wire everything back up the "stock" way and operate it as a 6-channel plane just to make sure everything works as it should. You don't have to fly it, just to test it. You need to declare it as "1 AIL, 1 flap, normal tail". If it works that way, that should tell you lots about the way you tried to make it work.

My suggestion is remove the gyro first and see if it goes away.

Actually, i´ve never fly it, i got it 3 years ago, got cancer and together with the pandemic.... no chance of flying it till now. To answer your questions:- Yes y have Gyro install A3-LV2 Hobbyeagle
- no mix between elevator and rudder
- Tx and RX (TY ai 10b) are Turnigy
- If i correct right elevator go down, i even detected some movement on the ailerons too.
I welcome any comments

"A mix between rudder and elevator" ......................... What does this mean? UP or DOWN elevator? Left or right rudder? What does the plane do? How much speed are you talking about? Is the plane still on the ground or has it just lifted off? Aileron is perfectly level? So many things can make your plane do what it does, if we even understand what it does.

You'll never go back to TP or no name batteries. I use SMC and like them a lot.
TP = toilet paper.

Bad comparison between the older F/A-18E and newer F/A-18C. That started out as a very light 3500mAh aerobat. The newer plane is far from that and a speedy, smooth, swoopy type plane, but heavier and with more power. The new one really is a great package and you have probably forgotten all the issued with the older V1 and V2, weak retracts, weak retract mounting, poor front retract door set up, poor steering setup. Foam, while it breaks cleanly, was easy to break. No rudders but yaw TV. The V1 had really bad horizontal stab mounting (most and 70mm jets now have much better ball links, linkage rods, pivot rods and mounting), the V2 was better but still not very good. The V1 wings glued on, V2 wing mounts were not very strong. The red pinstripes came pre peeled off out of the box...
Oh, and yes batteries. If you are going to be doing a set up where you are pulling 120A+ even if only using full throttle sparsely you better have good ones.

Of course a jet like this is not meant to be a speed demon, but the F-18 is pretty fast, and it doesn't like to land slow, so your review has me confused.
So, you are running the stock "high performance" 6S 1900kv EDF, correct?
It should be running a 9 blade EDF, not a 12 blade one so check that out, did you make a mistake or are you running the wrong rotor?
What timing have you set up on the ESC?
Define 'top tier battery' (brand and model, number of cycles and battery age).
Also, what altitude are you flying at?
What sort of runway do you operate from?
By any chance, has your rotor been damaged by from ingesting gravel or grass?
Are you sure you are talking about the Freewing F-18?
If so, I don't see what do you mean by 'flaps centering' since the flaps can only deflect down, so there is not much tuning to be done with them.
And unrelated, but I think speed is the least interesting parameter by which to judge a foam EDF.
Personally, I think hunting for speed is kinda pointless and boring, but to each their own... if that's what you enjoy, then, nothing to say!

Thanks Dave!
Hope so!
I'll try and get her on the workbench ASAP!

Hugh Wiedman Perhaps there are slight differences in the default settings for each ESC in different planes.

xviper as a quick follow-up, I took your suggestion and tried the HiV pack at a slightly lower voltage than the 4.35 per cell in the 3 EDF's that didn't work. The F-16 with the Castle ESC won't work correctly at anything other that 4.2-4.25 volts per cell, otherwise it assumes 7S and has a too high LV cutoff (so need to reprogram that one). The F-4 with the FW 130 amp ESC is the same, only giving 2 beeps and another long one so not sure what that's all about. Oddly, the other identical power system F-4 works fine at 4.35 volts per cell.
The F-18, which has a slightly newer 130 Amp ESC (now about 1 1/2 yr old) actually works at a maximum 4.31 volts per cell (or 25.86 volts), but at 25.9 volts it doesn't work. Strange that the other identical F-18 works fine at 26.1 volts.

So far, I've been very fortunate in that any of the planes I put the HV batteries into have responded correctly. As far as my newest F/A-18 is concerned, it's built for 8s and I'm not going to use any of the HV batteries in it.
Have you tried charging the HV to "not quite" 4.35V/cell? Say, maybe 4.3 just for those obstinate planes?
