FG Marder 1/6 nitro-gas: RCmag fully strips the large scale buggy in a video tutorial

French channel RCmag has just posted a technical tutorial dedicated to the FG Marder 1/6 gas buggy, the large scale machine from FG Modellsport. The format is simple and rare: the car is completely stripped down on camera, part after part, across two episodes published on 6 and 8 August 2026. A chance to finally see what really sits under the body of a petrol buggy of that size.

FG Marder 1/6 gas buggy: a complete teardown in two parts

The RCmag association, known for its road tests and its technical verdicts at the end of each video, chose to treat the subject “tutorial style” rather than as a simple presentation. Part one, posted on 6 August, opens the job; part two, published on 8 August, carries the teardown through to the end. The two episodes follow on from each other and should be watched in order, with support from modélisme34.fr.

What the Marder means in the FG Modellsport range

The Marder is one of the oldest and most widely sold buggies in the FG Modellsport catalogue. It is a large scale 2WD, built around a 4 mm aluminium chassis, with double wishbones front and rear, hydraulic shocks and a fully bearing-mounted drivetrain. The usual power unit is a 26 cc Zenoah-type two-stroke petrol engine, running on 95 or 98 unleaded mixed with 3% synthetic oil, with a 700 ml tank that allows long sessions without refuelling. This is nothing like the maintenance routine of a 1/8 nitro track car.

Why a full teardown matters in large scale

That is exactly where this kind of video becomes useful. In large scale, the vibration of the petrol engine and the weight of the model work the hardware and the rubber mounts far faster than on a 1/10. A second-hand FG Marder almost always needs a full overhaul before serious running: checking the bearings, the ball joints, the clutch, the rear end and the exhaust line. Seeing the car completely stripped makes it possible to spot the weak points in advance, to know which tools to get ready and to estimate the real amount of work involved before starting.

Where to watch both episodes

The first part of the FG Marder 1/6 gas tutorial and the second part are freely available on the RCmag channel. A useful reminder along the way: large scale gas power remains one of the most affordable ways into big-bore RC off-road, provided you accept the mechanical work that comes with it.
