Yes, the solution is sideways through the back so that they do not show. The fuel tank is not directly glued against the wall. But the idea is for the sound to be contained as well like if it was in its engine room. I personally prefer that my tanks not be too loud.

Hi,

Before completing the interior, i had to create the rear ramp with the opening mechanism at the front. The MRV had a standard M113 ramp and mud guards. Notice the cylinder on the right of the ramp. This amphibious apparatus contains a field phone, a weird design.

Ludwig does not provide much for the ramp, only this thin outer section and some hinges. This part is too wide and need to be reduced by 3mm on both sides. The rest of the ramp need to be completely scratch build but there is a residual plasticard section that is used on the door.

An additional plasticard of at least 1mm need to be glued at the back of the provided part to give the ramp the required thickness.

The small door need special attention as it needs to be working, with hinges and closing latch.

The installed ramp and mud guards, all finetuned according to reference pictures. It does not show much but there is a lot of little details on it.

The latch is easily made in 10 minutes with a brass strip of the right width, a metal file to shape it, and an M1 bolt with washer to install.

Opening the small door is an important feature of the ramp. The hinges need to be installed correctly so that the door opens strait.

The ramp is opening using a push rod (actually a Heng Long receiver antenna) inside a brass tube traversing the crew compartment, all the way to a servo at the front the vehicle.

A knupfer M1 hook is solidly installed on the ramp and connected to the push rod, in similar fashion as the real M113. On a previous M113 build, i attempted in putting the push rod under the floor but it was a failure due to the limited room under the floor. The rod was interfering with the suspension blades and there was too much friction because the tube had too many twists.

A medium size servo is installed at the very tip of the vehicle, in front of the driver position and with the push rod running under the driverès seat. It should not show much. I tried a micro servo earlier but it was too weak and did not have enough arm length to fully open the ramp.

This build thread is fun to follow and I’m learning how quality modeling should look. Merry Christmas!

Thank you, and Merry Christmas to you as well.

As you can see, my style is a fast build, usually 2-3 months per model so that I can focus on getting it done without getting tired of it, or interest moving elsewhere . I am using only basic tools like a hobby knife, metal rule, calculator, Dremel, plyers, a few metal files, 100 180 and 240 grain nail files from Amazon, a small drill with regular and micro bits, Dollar store superglue tubes, Meng nuts... Also need a good reserve of plasticard plates, brass strips, tubes, rods, bolts, washers and nuts of all sizes so that I do not have to stop the build and wait for material.

I feel my skills are constantly improving. I do not think everything needs to be 3D printed. Most items can be easily built with plasticard sheet and brass strips with great quality in limited time and effort. I have grown very suspicious of3D parts on the market unless expensive fine plastic and latest printers are used.

Regards, Louis

Presenting the interior, done on a best effort basis in order to provide something interesting to look at when the rear ramp is open.

Two interior lights were scratchbuilt, this time using 5mm LEDs. I found that 3mm LED are not powerful enough.

Here you can see the driver compartment. The light on the rear vehicle is installed on the roof but because this roof is removable, i did not want any loose electrical wires attached to it. The purpose of the large square box is unknown but there is a wire that will run to the turret base so i assume it could be related to comm. The vehicle radio is inside the turret.
