M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
Hi Everyone,
This will be my new build, an RC 1/16 scale M3A3 Bradley US Cavalry Fighting Vehicle. The following posts are from the planning stage, explaining what i am going to do.
The model will have the following features;
- OKMO M2A3 Bradley SLA and SLS 3D printed kit from DKLM converted into a M3A3 Cavalry fighting vehicle
- MATO Panther metal gearbox replacing the plastic gearbox coming with the kit
- AFV_Model Bradley/MLRS metal tracks with rubber pads and sprockets replacing the Sherman tracks coming with the kit.
- Elmod Fusion control board
- Servo operated opening rear ramp
- Scratch built detailed rear crew compartment interior
- Turret rotation with scratch built rotating turret basket
- 25mm gun elevation, auto cannon recoil and flash
- TOW launcher elevation with raising and lowering of the module
- Opening hatches
There are multiple versions of the Bradley. Some research is required to determine the variant.
Below is the initial M2 Bradley of the 1980s, coming with useless firing ports at the rear, trim vane for amphibious operations, little armor and early tracks with the triangular rubber pad. Pretty sure the squad firing ports would only have been useful during a zombie apocalypse to shoot at zombies hanging out on the streets.
The M2A2 had the firing ports blocked and featured new engine and spaced laminate add-on armor. The trim vane at the front was removed. Also shown here with early tracks.
M2A2 with the later Bigfoot tracks. The difference between early and Bigfoot tracks are the larger and squarer rubber pads, the rest of the track is the same.
The M2A3 below is totally digital and has the Improved Bradley Acquisition System (IBAS) and Commander's Independent Viewer (CIV) on the turret and shows latest T161 tracks. It has additional active and passive armor.
The main difference between the M2 IFV and M3 Cavalry vehicle is the crew compartment configuration. The M3 provides more 25mm ammo and TOW missiles, reduced infantry squad.
The latest M2A4 is now in production and is aimed at restoring the Bradley's mobility due to the increase of weight in previous versions.
Shown here are the OKMO M2A3 Bradley kit coming partially assembled from Carson of DKLM.
The armor and components come in multiple layers, which allow the builder to put on the fragile parts only at the end of the build. The model is expensive but is very nice and well printed.
View of the chassis with the plastic Sherman tracks on.
Views of the turret.
View from the rear. With its large opening ramp, the model is screaming to get a detailed interior. Notice how wide the Sherman T-80 tracks are. I am concerned that OKMO designed the side skirts too wide to accept the T-80 tracks. TBD later.

Re: M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
More view of the OKMO kit after the plastic gearbox and tracks were removed. The opening small door is great.
The model has an adjustable Idler.
Guys who saw my previous builds know that i am no fan of 3D printing, i am usually a old fashion scratch builder with plasticard plates. However, the quality of the print here is better than expected. I almost do not see the need for any sanding to remove printing lines. Due to the complex shapes and add-on features that stick out the Bradley everywhere, it would be very difficult to create this model entirely from scratch.
The opening engine access door will provide easy access to the gearbox for maintenance. How fragile the hinges are remain to be seen.
A few facets of the turret need sanding and preparation, but it will be limited by the extent of the add-on armor covering the vehicle.
The gun barrel has a metal tube inside.
The kit comes with plastic Sherman HVSS T-80 tracks and a 3D printed sprocket as a way to reduce costs for the buyer.
This is the plastic gearbox coming with the kit.

Re: M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
My first shock was to notice the two different connectors on this weird plastic gearbox. I have never seen or used such gearbox before. There is clearly two motors inside this gearbox but one motor is smaller than the other one, including a smaller connector...WTF.
Investigation is showing the plastic gears for the first motor. I am not inspired.
The metal side gears that connects to the sprocket gear when the gearbox slides in place inside the hull.
And the gears for the larger motor at the bottom of the gearbox.
An email reply from Carson indicated that such gearbox must be used with MODE2 on a Clark board but unknown for the planned Elmod. There is also no port that fits the smaller connector. I ran some tests by plugging the connectors to the usual motor ports on a Clark board... The gearbox runs really weird and i have not figured out how it really works but i managed to make the chassis move. It does not move in a realistic fashion, this gearbox is way too tight and light for such model. The loud voooooooo sound it makes is equally weird. Clearly, this plastic gearbox need replacement for my build. Other guys will probably find it acceptable if they manage to configure their control board to use it, or replace by a metal PDSGB if the suspension can take it.
View of the sprocket shaft that is connected to a large gear inside the hull. It allows the sprocket to be positioned forward correctly at the front.
View of the sprocket gear attached to the hull. Now the challenge is to install a regular metal MATO Panther gearbox with this. I think i've found a way.
View of the underside and suspension. Take note that the add-on armor at the front will hide the holes on the lower front plate.
View of the 3D printed sprocket and plastic T-80 tracks that are being discarded.
Investigation of the suspension torsion bars. Quite simple. But the overall torsion bar suspension is weak and will need reinforcement. The dampers are for the look only. I am still investigating replacement of the dampers with metal ones with springs. They would not show behind the side skirts. still TBD.
The suspension arms are held in place by the tip of the torsion bars using a single screw inside the hull. I would have liked something stronger.

Re: M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
Detailed view of the sprocket shaft, removable side cover and the gear that connects to the gearbox as it is lowered in place inside the hull.
The first and last set of torsion bars are a bit thicker and have more torque than the torsion bars in the middle. The thinner torsion bars for the middle roadwheels barely provide any support to the model, they are only good for keeping their roadwheels lowered, not good for a model with added features, metal gearbox and tracks. I have asked Carson to sell me 8 more thicker torsion bars to replace the thin ones, otherwise i will have to make my own replacement.
View of the inside of the sprocket gear with cover removed.
I will be helped by the MENG 1/35 kit of the M3A3, and its associated detailed interior kit. It is still undetermined if i will be replicating the BUSK III large add on armor boxes on the sides.
Some basic assembly was done for the planning stage. The Meng model has a very nice interior and i will use it for all interior specs. 1/16 parts for the interior will be scratch built by extrapolating from 1/35.
The plan is to detail the interior from the middle section, including the turret ring, all the way to the rear.
It will be nice to see the rotating turret basket as well, lit up display screen on the upper left and lights. Notice the storage racks for 10 TOW missile tubes on the right.
I am noticing a few differences in size and shapes on some facets of the upper hull but overall dimensions are good.
I am waiting for all the add-on armor to be in place before i give a final verdict on the model's accuracy.

Re: M3A3 Bradley US Cavalry Fighting Vehicle - RC 1/16 Build
Side by side display of the two models. You can see where i am going with this. A detailed lit up interior of the 1/16 will be a showcase similar to what i was able to do with all my M113s, BMP-1 and Marder IFV.
Some of the interior braces need to be remove and the model reinforced in a different way.
View of the interior of the hull with the old gearbox. The planned Mato gearbox are smaller/shorter and will leave more room for the electronics at the front.
Shown here are the Mato Panther gearbox with the basic plan to reuse the main outside metal gear of the plastic gearbox and transplant it to the Mato gear. The Mato exterior shaft will be modified to accept the external gear that will connect to the sprocket gear. The shaft size if perfect as the gear just slides in. Need to create a way to fix the gear on the shaft with upper and bottom slots filled with a metal lock, and then cut the extra shaft length. A new gearbox base will be built inside the hull.
Once every 3 or 4 years, AFV-Model of Germany produces its Bradley/MRLS/MARS metal tracks. They are expensive and are only available for a few months. I previously purchased another set of these tracks for my M-41A3 Walker bulldog. I think it was last year that i purchased this new set below just before they disappeared again. Originally purchased for a hypothetical M42 Duster build based on a Walker chassis, they are a perfect replacement for the plastic tracks for this Bradley build.
Very nice tracks. They also sell the metal sprocket. I did not purchase the metal idler wheel, yet. It is still available if needed.
Sadly, these are the Bradley early tracks with the triangular rubber pad, not the later Bigfoot ones with the larger rubber pad that would normally fit a M2A2 or M2A3. But using these is much more accurate and better than plastic Sherman tracks. I also have a plan to potentially modify these tracks to Bigfoot, tbd during the build.
Comparing dimensions of the accurate Bradley tracks with the larger Sherman T-80 tracks.
Comparing the 1/16 AFV-Model Badley metal tracks with the MENG 1/35 Bigfoot tracks. Other than the shape of the rubber pad, the shape and dimensions of the tracks are perfect for this build.
I purchased a sheet of 1mm thick rubber that can be easily cut. The plan is to fill the triangular slot in the metal track with a plasticard plate, and then create the larger squarer Bigfoot rubber pad and apply to each link.

Comparing the AFV-Model Bradley metal sprocket with the 1/35 MENG kit. Shape is excellent, right number of teeth, just missing one bolt on the inner ring...
The OKMO sprocket shaft will almost fit perfectly inside the sprocket, and will be held in place with the two hex screws. Just need to adjust the hole a bit, and rework the sprocket cover for the ball bearing location.
The planning and doability analysis phase is completed. The build will start soon, when i am finished with the painting of the A7V.

Nice acquisition Louis!
Looks like a lot of changes/upgrades needed for a pricey kit.

It is the metal sprockets that change the kit from don't waste your money to go for it.
I love printed models but without metal in the major points of stress they are a waste of money.

Indeed. But you know i am a big fan of American armor, especially IFV... and there is so few US vehicles available. The shipping from Hong Kong on this one was very expensive too. In the end, it will cost at least 2K in total (OKMO kit with shipping, Mato gearbox, AFV-Model tracks and sprockets). Reusable control board not included..
I bought it with the expectations that i would be replacing the gearbox, tracks and sprockets. I have never been a fan of 3D printed models but i have decided to try this one because i saw that the parts were well printed and would not require much sanding to eliminate the printed lines.
