The new star of the YS line of r/c airplane engines is the powerful YS170 DZ.  Inheriting the direct injection performance of the YS160 DZ, the 170 has rigorously tested and proven.  No other engine (4-stroke or 2-stroke) on the market offers more horsepower for the size.

A favorite of Pattern fliers, the 170 offers full power and clean acceleration all the way up the scale to full throttle.  No dropping out along the way.  The thrust is all there, no hit & miss.

If you need the power, the YS 170 DZ is your engine.  It powers pattern and scale rc aircraft up to eighteen pounds with astonishing performance, handling props from 15.5x12 four-blade on up to 18x10 wide well within normal operating rpm. 

One thing is certain: when it comes to Yamada engines in every size and class: you get your money's worth.  The YS 170-DZ engine has earned its place at the top in today's competitive pattern flying.

YS 170-DZ  Direct Injection

The YS 170-DZ takes up where the 160 left off.  Developed for serious aerobatics competition and large IMAC style aircraft, it differs from other YS Engines in that it doesn't use a pressured fuel system but a true fuel pump.  And then there is the power.  The YS 170-DZ offers maximum power.

*  Crankcase supercharging system unique to YS

    4 stroke engines

*  Fuel injected

*  Convenient fuel pump adjustment

*  High horsepower output with long service life

Even if you have no interest in competition, the YS 170-DZ delivers more thrill per ounce than any engine in its class — two or four stroke. 

The YS 170DZ can power model aircraft up to 18 lbs. with outstanding flight performance. Prop size ranges from 15.5x12 4 blade up to 18x10 wide, and the ideal RPM range is 8000 to 8500 for best flight performance. Recommended fuel is 30%.

YS 63-S

An Exceptional Engine!

The original YS63 was a great engine.  The YS 63-S is better.

The YS 63-S is redesigned to run even better under the toughest conditions. The regulator has been repositioned to run cooler in harsh environments.

The new YS FZ110-S  is here.  The most visible difference is the new position of the regulator, but this engine sports a whole new gut that offers improved power.  Only the tiniest added weight is more than offset by the improved engine performance.

 

Still a true 110 (same bore, etc.), the power boost comes from the new ring-sealed crankshaft (along the same lines as the 140-L and 160-DZ).  The result is a crankcase boost which delivers more power in the same sized engine.  There is a new rear bearing to accommodate the shaft.

 

Displacement 18cc
Bore 30.4 mm

Weight 730 g
RPM 2,000 - 13,700
