OK, this is the deal, I wanted to add the mid flap where it should be on the wings, just inside from the ailerons, to do this I had to split the wing tip into 2 parts to allow it to work, so I did this..

copied the wing tip and pasted it onto itself, imported the new LODs so that the 2 parts fit together like the full wing tip, deleted everything not needed (like pylons etc) put a LOD to the new midflap, checked and matched all refs to the wings in the Root etc so that the "new" ailerons worked and the flaps worked, basically got everything working right.

Before I did this the a/c was almost perfectly ballanced left to right, but now there is a sharpe pull to the right hand side, it can be trimmed easy enough although it needs alot, and the AI can still take off, but only just, but it is a problem.

Does anyone have any idea what to check or what to alter? both the mid wing and wing tip have all the same properties and airfoil data, although I had to move the point alot to allow it to take off now, but I just can't get rid of that sharpe pull it's giving now, looks almost like the right wing is givving alot less lift than the right, and so tipping it that way.

As always, any and all help is very appreciated

Also I see that your dihedral is in the mesh, this is a big no-no. Just model the wing flat in your 3d program then rotate the wing root in OPS to get the correct dihedral. You must do this if you want dihedral to be in the FM.

AirPoints MUST be fixed! Put them near the center of each wing section about 1/4 the way back from the leading edge of the wing. Now if you have balance issues, just alter the CG, this is easy.

WingTipR2, WingTipL2 have "airArea" in the obAirfoil prop list, it should be in the root prop list like the other wing sections. Maybe it does work here as well, I do not know.

MidFlapL1 has DOf with max 15, all other MidFlaps have max of 20. This is not the bug though, just something I saw.

I am quite stumped right now. Maybe a quick look at the vectors in the sdoe dbug will help determine what part has more/less lift, but it is hard to make out small differnces this way.

I am stumped! It looks like everything lines up, but you can not tell by looking. Did you rotate ANY of the wing parts at all? Or did you just move them?

As for the wingtips that I added, they are the outer most tips. I didn't rotate them at all, there was no need to change anything, takin the logical view that it flies ok with 2 part wings, i took the simple step of simply copying the wingtip, and pasting it onto itslef as a child of the original wingtip, then simpley changed both the LODs to the ones I had for the middle wing and the wing tip, so no data was changed at all, purely the LOD (if data doesn't match perfectly now it's down to my attempts to correct the bug) but the first time I did this only LODs were changed and it pulled hard over as you see it now. It flew about as well as I wanted it to before doingthis, so I really don't know why it's messin with my head now, even with the other small things you've mentioned, they didn't affect the FM in a detrimental way before.

Thanks alot for takin the time to help out with this SV, sa you can see, it needs it.. LOL, either that or I drop the mindwing flap and go back to a 2 part wing... last option if all else fails I guess.

PS, shouldn't Jets creat an airwash? I was actually thinking of making it bigger thinking that jets created a larger wash.

the flaps I set that way on purpose, purely a question of eyecandy.. the mid flaps are so much bigger they just didn't look right when lowered compared to the smaller flaps, this way they look to me like they come down together to the same position... no biggie

I'll make the other alterations you've mentioned (saving a working version now) to see what it does, I'm a little nervouse about doing it because until the change in the wing the FM was correct even if things aren't how you would expect to see them, I think the FM being right is more important than the data/positioning being correct and giving a bad FM, but I'll try it out and tweak around till it's sorted

Thanks alot SV, least I know I wasn't missing something obvious now lol

I just removed one of the inertia boxes from the nose (large one) giggled a little with the CG, placed the airfoil points about where I thought they should be and flew in my test mission (multiple aircraft/air + takeoff starts/multiple loadouts) and the pull is all but gone I'm sure that when I reposition the airfoil points more acuratelay then it will be fine now.. oh, raised the wing are to 250 per wing, on my version I'd already removed those other area refs.

So, now into the FM fine tuning mode again and all should be fine. Thankyou SV for helpin me out here I owe you.. might let you shoot me down online one night LOL

Thanks!

Isn't airWash created by the turning prop generating a cork-screw airflow that strikes the vert stab? I know it only takes effect when the throttle is up, the airWash caused a bug in the SE5a FM where any time you idled the engine in flight the SE5a pitched up fast. This was becuase at full power the airWash was holding the nose down

As far as the 15/20 DOF max thing, check it: one side has 15 and the other side has 20 for one of the flaps.

The model looks great, and the break down of the wing makes sense to me - but having the dihedral in the mesh is not a good thing. But if it is not causing any trouble, leave it My old old SE5a had the dihedral in the mesh, I had to redo it and that was not at all fun heheh.

So you also see that Raider has a genius hack that will let your gun spin 'round? Cool, eh?
