The inclusion of an air shock absorbing mechanism into a spring action, scale looking strut is new in the model airplane arena and its no coincidence that BVM did it first. The air shock action gives us a strut that minimizes bounce on landing and generally smooths out take-off and landing rolls. This is most evident during grass field or rough runway operations. The air shock feature requires that the anti-torque links be manufactured exceptionally strong and accurate, and BVM's are. They are precision cast from beryllium copper and then hand fitted. The outside strut must be hardened and precision honed to fit an equally precision ground and nickel plated inner strut. These parts fit like a piston and cylinder in your engine. We then add an internal "O" ring to insure an airtight seal. The aluminum castings are designed for function and scale appearance, and the main gear struts are equipped with strut door holding bosses - even provisions for routing brakes lines have been accommodated. There is a Duro-Strut to fit your modern BVM jet and BVM retract unit, and you can be sure that we have flight tested each design thoroughly before releasing the product. Check out the dimensions below and you may find that they probably can be adapted to one of your other models.
