YS Engines: More Power, Greater Performance

For many rc flyers, its time to face serious economic facts.  This is not a time to waste money on cheap products that may or may not accomplish what you want with your plane.

YS Engines are not cheap engines.  Yet they will always prove to be the better buy.  These engines are not designed to provide mass-market retailers with another low-end, low-priced product line, but to provide serious flyers with a dependable power plant for even the most extreme radio-controlled flight.

YS builds engines under strictly controlled conditions unheard of in most manufacturing plants.  Where most factories measure success by how many units are cranked out each day, YS measures success by the performance of its end product. 

Tolerances at YS are not a minor thing.  Standards are maintained.  The manufacture of these precision-crafted engines is carried out by hand, by family, in Japan, and not in a remote factory somewhere that put in the lowest bid.  The goal at YS is very simple: Consistent excellence in a superior product.

YS engines are built to perform, to withstand a wide range of flying conditions, to keep running well at high temperatures and to withstand continued operating pressure.  They are built to last.  Parts are regularly stocked right here at Central Hobbies, ready to ship. 

It isn't really a difficult choice to make.  Instead of frequently replacing or rebuilding lesser, worn-out engines, serious flyers prefer buy and fly the very best.  It makes perfect economic sense to buy the engine that will consistently deliver on its promises.  YS is all about, more power, greater performance and superior dependability.

This is the Warbird Race edition of the YS FZ115. It has a dished piston for use with high nitro fuels and a crankshaft seal to increase the supercharging affect.

It does not come with a muffler or a glow plug. We recommend the NMP Aluminum Racing Stack for the exhaust and a YS 4-Stroke glow plug.

The YS 140 Sport is one of our most popular engines.

This engine is very easy to operate with smooth running characteristics and the ability to run well on fuel in a variety of nitro percentages.   But we still recommend YS 20/20 fuel for best results.  Fits the same area as the 1.20.
