Hey guys, I've got the A10 sorted out again.. but I have just read that the A10 should never exceed 518mph, thatbeing the case, can someone explain how to cause the wings to detach at a speed close but above to that speed?

Also, does anybody know ir we can add recoil to guns? I'd like to do this with the Avenger in the A10, causing a backwards force slowing the aircraft when the guns are fired.

Thanks for any help guys

Look at the F2b rear lewis guns, they recoil.

Nat, getting the wings to detach at a certian speed is a very time consuming trial and error kind of thing.

Look at most planes, they have dof's on the wings, by adjusting the dofSpring value, dofBreak value and Max, Min values, you can fine tune the speed at which they detach.

The Max and Min values are the amount the part can move with no problem

dofSpring is the amount of resistance

If the part moves between the Max and Min the dofSpring will bring it back into alignment, but if you exceed the Max or Min it will break.

dofBreak, is the amount the part can bend before breaking. If the part exceeds the Max and Min but is less than the dofBreak amount it will not break nor return to its origin.

As I understand the dofBreak value, it is multiplied times the Max and Min value

if Max is 2 and you set the dofBreak to 3, that means that;

The part can move 2 degrees and will return to its origin,

If it exceeds 2 degrees but less than 6 degrees it will not break, but will stay bent - not return to its origin, (This also makes the part seem weaker - because it does not have to travel much to exceed the max allowed to break)

If it exceeds 6 degrees it will detach.

I suggest working on just one wing, start with the settings of an existing plane, Test it, if the wing breaks too fast, double the dofSpring, If it breaks too soon, reduce the dofSpring by half of what you have already tried (Example, Start at 10,000 - breaks too soon, set to 20,000 - does not break fast enough, set to 15,000 etc. this should get you zeroed in.

Also on the Alpha2 Harrier that gun underneath recoils as well.

Actually, the wings probably wouldn't break off at anything close to 518 mph. On most planes the wings themselves are usually massively overengineered. On the A-10, it can lose one of its three main spars and still return to base.

At VNE, usually you start shedding other ancillary parts, like engine nacelles on the B-17. Or damage moving parts, like ailerons, or hydraulic systems etc. On the F-4, it's top speed was limited by the temperature of the windscreen.

Oh, and we already model recoil. If you've put in the correct numbers for the loadout you should get appropriate thrust.

A few of the bombers have gun jiggle modelled by the addition of a small spring DOF, so the game does model recoil.

it's not the actual barrles popping backwards and forwards I was hoping for, thats just a simple spring dof, rather, I want that Baby to almost stall when the guns fire as she should, wheich means in some way having actual recoil.. force an all when the guns fire, I thought I'd seen this someplce but I'm not really sure.

Mighty, whats that to do with the loadout?

I made (just for fun) that rather large cannon that Crossbow did for the Me-262U4 have a HUGE recoil. When I shot it standing still the plane rolled quite a bit backwards. Then in flight, the aircraft slowed down and the nose would pitch up or down because of the recoil. To change the recoil, you need to change the velocity of the gun. Open up the loadout.ppf file and change the gunMV. I do believe the SDOE engine does not model recoil too accurately...... but it does model it.

Hey thanks Argon I must admit I haven't got MV details for the Avenger yet, I'll go see what I find
