Wing Tanks. I printed them at 2% infill to keep the weight down.

Wow Vic;

Thanks for sharing the files, really appreciate it! I didn't see the wing tank files attached on here or on Thingiverse though... Do you have those handy by any chance?

Thanks;
Eric

Yes and handy to have him around too (Vic) 😁.

I messed around with the front strut this morning trying to get the nose down stance and the proper angle of the trailing suspension. It can be done but then the nose wheel hangs out of the bay when retracted. I don't see any way to do it that wouldn't require moving the whole retract assembly.

I did replace the wheels on mine with the F-22 mains on the mains and a Stinger 90 main on the nose. Those look a ton better.

What a great age we live in, where we can all congregate on one common forum and even develop/print/share these add-ons with everyone.

Finally there are the wheel hubs. The OV has low pressure tires to be able to operate off of rough surfaces. It has large tires with small wheel hubs. I have printed a small hub that covers the spokes on the OEM wheels. I plan to paint the OEM wheel black to match the tire and then place this smaller, white painted hub to simulate the look of the full scale item.

Well, that's all I have for now. Happy flying!

Airframe components

Canopy Handles
Wheel Hubs


The canopy handles are designed to be installed from the inside of the canopy frame. They are on both sides of the aircraft. Remove the canopy. Cut a hole large enough to fit the handle through the hole from the inside and glue the flats to the canopy frame using contact cement.

The OV-10 has a windshield wiper and I just downloaded one for a helicopter from Thingiverse and used it.

Mirrors

These are the 3D printed parts and the looked pretty good with the silver HVAC tape stretched over them. For my FPV use though, I wanted actual mirrors. They work but they are limited in their functionality.

Gunsight Panel

[vduniec]

There's a lot for the cockpit and I really designed it for how it would appear when I fly it in FPV. The aft cockpit is untouched and I don't have plans right now to do anything for it. The gunsight is pretty basic and it blocks a lot of the forward view on FPV so I elected not to use it on my plane but it will work for non-FPV cockpits.

Cockpit components are:
Gunsight
Gunsight Panel
Rear View Mirrors
Air Vent
Wet Compass
Port Armament Panel
Starboard Armament Panel
APR-39 indicator
Left side console with throttle quadrant
Right side console

The Chaff/Flare buckets go on the outside of each tail boom. Place the part according to the picture displayed and press it into the foam so that the back makes an indentation. Then cut out the indented area and the bucket should fit right in with the faceplate sitting around the outside of the fuselage. Be careful when cutting because there are wires that run through the boom.

Next up is Ordnance. I designed the wing pylons and tanks. There are many other ordnance files that may be accessed from Thingiverse. There are Zuni pods for the Freewing A-4, same scale that can be used. There are also AIM-9 and launch rail there. The launch rail will have to be resized and cut but it's relatively easy to do. So for my contribution I just have the following to offer:

Wing Pylon
Wing Tank
Chaff/Flare Buckets

The wing pylons are designed for use with the Freewing 90mm F-16 weapons attachment system.

Previously posted but in keeping with the grouping, here are the FM Antenna Humps. I used a broom bristle painted black to represent the antenna.

[vduniec]

High Frequency Antenna mounts. The wire mounts underneath the horizontal stabilizer and the atop the aft fuselage next to the IRCM system. In order to make the antenna wire removable during transportation, I affixed one end with a fishing swivel/snap connector and the other end with a small rubber band to keep it under tension.

[vduniec]

APR-39 Radar Warning receivers. Positioned on each side of the nose and on the top of both outboard sides of the vertical tails. Combined, these receivers provided 360 degrees of coverage.

[vduniec]

Ok. All of the 3DP stuff I wanted to make is now complete! I'll post in sections along with their accompanying locations. These components are designed by me using Tinkercad with all of it's (and my) limitations. These components are not 100% accurate but give, I feel, a close representation to the actual items. These items represent what USMC aircraft had from the 1980's until the Bronco's eventual retirement from service. Breakdown will be:

Antennae
Cockpit
Ordnance
Airframe

First up, Antennae

ALQ-144 IRCM

The "disco ball" was mounted atop the rear fuselage later in the service life of the OV-10. The part was printed and then painted. For the reflective surface, I use Solyx Specturm Dichroic Sample. https://www.decorativefilm.com/solyx...-dichroic-film The sample is free but you have to pay for shipping. I also use this film for my HUD's in planes and it gives a great effect. I cut the film into strips and used contact cement to glue them in place. I'm pretty happy with the end result.

Holy crap this is confusing...lol Well I think I have settled on the 1800mm balsa bird for my purposes. There is a ton of good info in this thread though. I might still do the foam one later on.
