3d Printed Part Sets - Freewing F-4D Phantom II

[Dirty Dee]

Here is the centerline tank. 94g with ABS and printed in 3 parts. I should have it up on Thingiverse tonight.

Functional as in using it to catch a "wire" on the runway to do an arrested landing?

that would require a far more secure attachment than is needed for the landing gear. It would impose several G of deceleration force on the aircraft.

I've done arrested landings with control line. 1 lb sandbags each end of the arresting wire, 1/2 inch thick solid balsa profile fuselage with 1/8 inch thick aircraft plywood .reinforcing plates at the tailhook attachment point, 8-32 bolt as the pivot pin, and commonly sheared the bolt. (which was the cheapest thing to have break if the landing was too fast)
And that was a much lighter and slower model.

No don't plan on actually stopping plane.
On my t45 when I drop landing flaps I have the tailhook also drops,have servo connected to a spring when the tail hook contacts the ground it just floats .
Doesn't do anything except look amazing on final with everthing down and dirty.
I have played with trying to catch streamers on the runway.

Hey guys can anyone make a scale tailhook for the F4,I would really like to make it functional.

Downloaded stl files, ordered SLA printer. Would try to print those parts. Wish me luck!

Thanks, Pat!

Those are chin modifications for the nose cone. The straight one turns it into a C model (stock is a D model). The one with the bump is for a plastic chin for the D model.

I bought the upgrade F-4 cockpit parts as well as the two engine exhaust upgrades. Everything worked out pretty well, however on the cockpit parts I had two parts left over and I have no idea where they go. I"ll post a pic of them. Can anyone tell me where these are supposed to go on the airplane?

Not to be duplicating efforts, but I made a 600 gallon centerline tank as well. Bartered with dlxpkg for a pair of wing bags for my A-10 in return for a printed centerline tank:)

Some design differences from apmech1's, like utilizing the stock FW hardware as well as I added the aft sway braces. Will upload to thingiverse after I finish printing them and make sure they are good.

Looks good DD. Just a personal note: On a part that size I use two brackets to help distribute the load. My preference but just in transport alone it is subject to getting bumped. It is very solid with two and it also helps to keep it aligned.

DD,

I like your idea of adding just the slot for the slide on attachment. Less supports needed that way. Looking forward to seeing it on thingiverse!

Anyone with a 3D printer interested in making a swap? I can make a drag chute for a set of Freewing F-4 nozzles and cockpit upgrade. Thanks!

[Helmsman52]

The Prusa did an awesome job on the nozzles! Printed them nozzle end down and used supports to get the detail. I've got one painted, doing the other tonight and installing. I used Model Masters Steel on the collar, and Gunmetal on the exhaust.

Looks great Pat!

Printer is calibrated and test prints successful. Printing up some ordnance and F-4 3DPUP files now!

At some point I plane to get the multi-material upgrade. It can print up to 5 materials in a single print!

Prusa made an update to the spool holder, you can now load up two spools on it. I guess it's so that if you want to change colors, the spool is already there, just remove the filament from one and put in the other.

That's sounds really handy! Its great that they continue to improve this product. Sadly, I will have to change mine out one at a time, the old fashioned way. Old and busted VS new hotness! :Clown:

I've had very good results (used almost one roll so far) but I've read that its best to keep the reels in a bag with a desiccant, because the filament can absorb moisture over time. The quality of the filament can greatly affect the way the parts turn out. So I've been told.... I guess the secret is to use the roll up before it can go bad!! Yeeha!
