   New !   RCV90-SP 4-Cycle  Engine 

The RCV 90-SP is fitting neatly between the 60 and the 120, it combines all of the design and technical achievements of the existing engines and will bridge the gap between the two.  Now there is no reason to use any other 4-stroke engine between a 52 and a 120. 
The RCV90--SP  can be used in any sport or scale model that would normally use a four stroke 90.  It can however fit most models with airframes ranging from 70 - 80 - 90.
The compact streamlined shape means that fully cowled installations are that much simpler to arrange, and the 2:1 output gearing means that larger more scale like propellers can be used.
