That looks great! Is there a craft file? I wonder how it would perform in space.... 

Soon :-)

 AA flak gun!

Yes, that did cross my mind :-D

Just started work on a F/A-18 Hornet replica, but stuck on the wings and intakes. Any suggestions?

A thing I do wor wings sometimes is use the smallest wings and build to lines of them then rotate into the appropriate angle and adjust to fit the look.

Intakes... I'm not sure. I've used the circular intakes for a rough replica.

Also, the whole thing looks a little short and I think the intakes should come down more.  NCS adapters are your friend for making a smooth-ish transition.

Look, I swear I wasn't TRYING to make an F-4 Phantom... it... just sort of came out that way.

Okay, maybe the napalm canisters were intentional... and the anhedral elevators... But that's it!

The missiles are't working very well, one of them always seems to fly off course (in this case it was the top one).

Fortunately the wings keep this from being a solid F-4 replica and make it more of an unlicensed knock-off. It's not the best dogfighter, but it's fast enough that I guess it would make sense to use it as an interceptor.

Theres a few things you can do to troubleshoot the missiles. If you haven't already, roatationally offset the seperatrons so the missiles spins, the balances out minors aiming problems and makes the missiles more stable. If you have offset them from the decoupler, they will sadly be inaccurate, which I found out the hard way. Another thing it might be is the missile may be hitting a part of the wing on release, to fix that you have to mov the hardpoint. And finally, the way symmetry handle subassemblies of parts is strange, and occasionally get rotation wrong. To check this isn't the case, turn of symmetry, make a copy of the working missile, then rotate it 180 and attach it to the other hardpoint. This also has the benefit of allowing you to single-fire the missiles.

If none of that helps, I'm stumped. :D

What is the rear engine nozzle for?

 

Sugar and spice Saturday Day's Dawnin' ain't it sir? :-P

Why ... ter cancel aahhht the bleedin' backfire of course ;-)

Tested wif Bo-le Of Glue firin' from the wings of wahn of me choppers. Slightly forgot ter set the stagin' properly, nearly flipped it upside daahhhn!

You are as incomprehensible as the fine 'east end of London' chaps I work with. :-)

 Having grown up with folk who speak elequent English the 'other' English accents cut through me like a knife so enough of that thank you. ;-)

 considering your weapon is a single shot, fired by motor thrust and mounted on an aircraft I can say with certainty it is far too big. Must make smaller. ;-)

True, it's large and way too heavy. Plus it's ineffective, usually the objects just phase through the colliders of other craft at high speed. We'd need far more precise physics calculations. The reason the BDA team have chosen to create armor with a special Unity gameobject and custom module to handle these collisions.

But it was a fun exercise, to see what we can do with these pretty little balls RCS balls with 50m/s impact rating. Apparently a whole lot. I'm sure @klond and @Bubbadevlin can build a machine gun with this ammo, being the mechanical experts on this forum (and I'm sorry if I missed someone, there are lots of experts here). The good thing about this, for a single shot, you wouldn't need the heavy engines I used, two afterburning Panthers is probably enough.

Klond made this awhile back, it's awesome!

LOL, @klond, yes. ;-)

Just noticed this and I feel honored lol. The RCS balls could definitely be used for ammo, TBH i have been trying to make a gun with a similar idea, with not much luck though :/

Are you trying to build a baby hornet?

Quick update on my F-18:

[snip]

First_YF-18A_Hornet_on_display_in_1978.J

McDONNELL_DOUGLAS_F-A-18_HORNET.png

Proportions to me look slightly off as well...

The razor back looks like its too high, nose maybe short, and the intakes too far forward. The rear half (bit with engines) is about the same as the front half (part before the intakes). In the picture, seems its more of a 1:2 ration of parts infront of the intake as opposed to parts in the back. Then again, could be camera angle.

I was basing it off this picture: (Nope, mobile is not cooperating with me. If you look up the Wikipedia page on hornets, the first picture there)

I think the problem is the LERX are too short, and I've built the fuselage around them. Though the intakes start just behind the LERX, and I've used the intakes as a sort of halfway point. I'll definitely look at it again when I get back from holiday. I'm thinking extending the cockpit with gravioli detectors, possibly try and add more landing gear to extend the razor back and lengthening the back fuselage with half a mk1 fuel tank.

Ah, ok. You could also try using solar panels to extend the cockpit. Personally, easier since you don't have to do minor adjustment. That being said, I did use the gravioli detectors on my vertijet.

I don't think it's tiny at all? 

No no no, that's not what I mean by "baby" hornet. (I'm not sure how much the civilian world uses the term "baby" when talking about the old hornet. I grew up with a dad in the navy who always pointed out the differences between the 2, and always used the phrase "baby". I was just using a term I was used to using and was familiar to me.)  The are 2 different "flavors" of hornet- the so called baby hornet, and the super hornet. The main visible difference on the surface between the "baby" hornet are the shape of the intakes, the super hornet having rectangular intakes and the baby hornet having circular intakes. The super hornet is also newer than the baby hornet. (And the Super hornet is also slightly larger.)

The answer to this, AFAIK, is "not much, if at all"

Also, I can't remember, but are all flavors of the Super Hornet twin seaters?

Edit: Should have just looked it up. F/A-18E is not, F/A-18F is (a twin seater).
