Compact Radial Engines Inc. manufactures and distributes their "MZ" and "SC" series multi-purpose two-stroke engines from their facilities in British Columbia Canada.

-The "MZ" series has models from 18 hp with a single cylinder up to 85 hp, with several cylinders.

Compact - MZ-100
"MZ-100"

-The MZ-100 with 18 hp at 9,700 rpm, is a single cylinder with a multiple-belt speed reducer for PPG applications.

Compact - MZ34
“MZ-34”

-The MZ-34, with 27 hp at 6,250 rpm for ULM and PPG.

MZ-35
"MZ-35"

-The MZ-35, with 27 hp at 6,250 rpm for motor gliders.

Compact - MZ-201
"MZ-201"

-The MZ-201 is a two-cylinder that gives 45 hp at 4,700 rpm, for ultralight aviation.

Compact - MZ-202
"MZ-202"

-The MZ-202 is a two-cylinder in-line engine with a forced air blower. It gives 60 hp at 5,800 rpm. For ultralights and PPG.

Compact - MZ-301
"MZ-301"

-The MZ-301 gives 85 hp at 5,800 rpm and is used in ultralights, hovercrafts and experimental aircraft.

Compact - SC-430
"SC-430"

The "SC" series consists of radial motors. The SC-430 three-cylinder gives 20 hp at 4,200 rpm, for powered paragliders (PPG).

Compact - SC-570
"SC-570"

-The SC-570 has 4 radial cylinders, gives 24 hp at 4,200 rpm and is used on motor gliders and Ultra light aviation.

-As we can see, the two series are air-cooled and 2-stroke. There is a possibility of adapting a reduction gear unit with a centrifugal clutch.

From Appendix 10: They keep expanding the range with new products, we highlight the most used in this year 2015.

SD-570

"SD-570"

The author of this edition of Aeroengines AtoZ, through Aeroteca, collaborated on Version 2 of this video, which is presented here.

To understand the operation of the connecting rods, the 1929 Continental R 670 single-cylinder engine was chosen.

A demonstration of Version 3, improved at the author's suggestion, is also available on YouTube at a later date. This version shows bronze valve guides, improved valve spring movement, and the split crankshaft counterweights and front bearing balls also move.

The design is from Juan Soler, Sant Cugat, Barcelona

Below we show a flash of version 3

Counting also with the coloboration of JMC of Enginys Mecanics in Mataro, Barcelona
