  • QUARTZ Vertical is suitable for 4-blade-propellors with diameter from 40mm to 55mm
  • The QUARTZ Vertical engine is available either as a „ready to run“ finished engine or a completely machined kit for self assembly, no soldering required.

Steam-Engines do not need to be large!

The concept of this engine is born out of a need for a compact, light but attractive unit of high quality and reasonable price and especially suited for small and middle sized models and model-boat-kits starting from a displacement of about 3 Kg (6 – 7 lbs)

Controlling the engine is very easy because you require only one servo to have full control over over all aspects of running the engine like regulating the speed, stopping or reversing. This makes this engine also particularly well suited for models with twin propellors.

As with all our other products, we took great care to achieve durability and robustness when designing the QUARTZ Vertical. The central shaft of the crankshaft is of stainless steel and is running in 3 solid brass bearing-blocks, piston-rod and piston-valve are made from from stainless-steel, the excentres are made from steel. All other parts are machined from brass.

The QUARTZ is a design with clear lines but of well balanced proportions, thanks to the classic design with its four brass columns the engine has an aspect of lightness and grace.
