Any progress Dan? Come on, it's been 5 whole days since the last pic. You flew it last weekend right?

Hi Steve,

Yes, as a matter of fact. Well, to the progress part. I'm still not at the flying part, yet.

I got the tail cone and splitter plate mostly finished. I still need to rig the elevator linkage and then cut the slots in the sides of the tail cone hatch.

After that, I'm not sure what else needs to be built. I think it's about time to final sand everything, then start mounting the wings and tail feathers.

Looks cool, Dan. Having the splitter really adds to the look of the Phantom (don't ask how I know ).

Steve's right! I dont have hook and i'm totally wierd!

nice Dan!!! reminds me, Ihad a thought I was too chicken or didnt have enough time to experiment with on yellow F-4. i had the thought why make pants outlet when maybe a splitter wall could be instlled permanant in plane, then a v notch in one pipe tail made the fit as it slid in. Thenit wouldnt have to be perfectly curved all the way in, as long as it acted infinite it could be curved in back but go to striaght knifed infiite wall inside wher it esay to enguage. course this could be exctly what you've done here but outside I suppose?

Thanks, Kevin,

That's good to know. Did you notice whether it had any effect on the thrust?

No noticeable effect at all.

Thanks, Daren! Even though it looked right, I got so used to how it looked with out the splitter plate that when it and the hatch were mounted on the airplane, I thought the plane looked chunky in the back. Now, I've gotten used to it and it looks okay.

I had a weird experience while I was building the hatch. As I was sanding it to shape, I had to keep pushing it back into place and every time I did, it squeaked the sound of wood rubbing against wood.

I traced the sound to the front bulkhead of the hatch. So, I would sand the mating surfaces between the hatch and the fuselage bulkheads and it was still squeaking!

Then I realized the magnets were what was causing the two surfaces to be so tight, they squeaked. After this, I stopped sanding.

I found your WM400 F-4 thread. Nice jet, BTW. Yours and mine use a lot of the same construction techniques. (See: F-4E build for the WM400)

I was curious how you did your tailpipe. It looks like ours are very similar, being tucked up under the tail boom.

Do you recall what your F-4's thrust line was set?

Thanks!

When my wife saw the hook, she asked if it was to launch the model. I explained, that no, it was to catch the real aircraft landing on the carrier deck.

Me, too! What a co-inky-dink!

Interesting concept. Or, maybe just use the splitter wall to divide the flow into two separate tubes to make a true twin-outlet. I may try it in the future.

Yeah, more or less. I decided to use a squished single tailpipe mainly to avoid the thrust loss and complexity that comes with bifurcated tailpipes. I made the hatch/splitter plate removable so I could take the tailpipe in and out the back.

I'm also a big fan of box with wings construction....but you knew that .

My thrust line was zero but I gave the stab a degree of negative incidence (trim to climb) but found it didn't need it

Oh, yeah!

Hmmm... That's good to know about the thrustline. Mine is also at zero. That's interesting about the stab incidence. I sanded mine into an inverted flat-bottom airfoil. It'll be interesting to see what, if any, effect it has on the handling.
