Our national and international success is based on our 20 years Know-How in producing 2-stroke engines. The 34 years of industrial experience of our design engineer had been realized in our new range of engines representing the latest state of the art of 2-stroke technology.
Having this in mind we had to develop a new generation of mufflers considering the higher degree of saturation and process of combustion efficiency.

3W has developed these mufflers - now we are able to introduce ourselves as a supplier for complete solutions of 2-stroke-power systems for airplane models.

Use our experience and ask for a quotation putting together your ideas, our know-how and innovation to develop your specific engine or even drive system. We are able to fulfil your requirements, using the latest state of the art of technology.

  Quique Somenzini won this TOC with 3W-120B2

• Most popular manoeuvre and spectacular at the TOC: Torque-Rolle.
  most used engine: 3W-120B2

• start of the new - i - series with new piston- and cylinder technology. the first engines were: 3W-70i and 3w-75i

• Steve Stricker wins the TOC with 3W-160B4 and his 3400mm Extra
  Development and production of 3W-50i, 3W-100iB2, 3W-78iB2

• 3W received a patent no 4408908 for the first two-stroke three cylinder radial engine 3W-105STR3 with integrated planetary reduction gear drive unit
  Quique Somenzini wins TOC

• co-operation of many years with Quique Somenzini leads to the development of the - QS - engine series. Quique Somenzini wins TOC with his new 3W-150iB2 QS engine with four real transfer ports
  Development and production of 3W-240iB2 opposed twin

• Quique Somenzini does the hat trick and wins TOC with 3W-150iB2 QS again.

  the third generation of our ignition is in the field. these processor controlled systems have a programmable ignition timing which was specially optimised for 3W engines. technical datas of ignition:
  voltage-range: 4.8V - 7.0V
  operating Voltage: 6.0Volt
  standard feature: sensor output signal for tach-meter
  temperature range: from -104 and +104 degree F

• Finishing the design of five cylinder radial engine 3W-256STR for-stroke
  Introduction of four cylinder opposed 3W-684iB4 with 41.74 cu.in. as well as the two cylinder opposed 3W-342iB2. Both are two-stroke engines

• in the meantime we produce engines between 1.46 and 41.74 cu.in. our range of engines contains twenty two different cylinder capacities in forty seven different variations.
  3W is the only model engine manufacturer producing four and six cyl. opposed since 18 years.
  production of 3W-28i, 3W-56iB2, 3W-112iB4

legend of airplane-models

• 3W sets up his own airplane-model series. These models are exclusively produced for 3W and are developed in co-operation with the worlds best pilots.
  The design of these airplane models are influenced by the expert knowledge of P. Weinhold in building over five hundred models.
  The last kick was given to the models by Wolfgang and Roland Matt, two international well respected model pilots.

• meantime we produce sixteen different airplane-models in twenty one different wingspans between 78.74 and 153.54 inch.
  specially for the pilots with the wish of a weight-optimized plane we offer many of our models in the super light competition version. these airplane-models are mainly build in honeycomb sandwich technology

3W simply the best
