RCV90-SP



	RCV90SP 4 -Stroke Model Aero Engine

The RCV - rotary cylinder valve four stroke engine represents a major advance in model engine design.
Although its moving components (piston, crank, cylinder and rotary valve) are totally conventional,
they are arranged in a radically novel configuration to provide the aero modeller with several key benefits,
whilst having similar handling characteristics to other 4-stroke model engines:-

RCV90-SP - 0.90 cu in / 15 cc

SP Series Features

Streamline shape, perfect for cowling

2:1 Reduction Gearing

Uses Scale Props - 2, 3 & 4-blade

Low Maintenance

Behind the prop starting facility

2-Year Guarantee

The RCV90-SP was designed with the scale modeller in mind. This quality CNC machined engine has a similar power output to conventional poppet valve 4-stroke engines and can be used in scale or general sport models that would normally use a 4-stroke .90 or a 2-stroke .60. Check out our gallery for examples of what the RCV90SP is capable of flying.

However the RCV SP series offers much more. The compact streamlined shape means that cowled installations are that much simpler to arrange, perfect for warbirds, and the 2:1 output gearing allows for larger scale like propellers.

The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. One more benefit to RCV SP engines is the behind the prop starting facility (now included with the engine), which allows the modeller to stay behind the prop at all times

So if you are looking for a reliable, streamline 4-stroke engine, that is capable of pulling scale size 2, 3 and 4-bladed propellers, our RCV90-SP engine is a perfect option.
