Y.S. 170DZ with Direct Fuel Injection

• Crankcase supercharging system unique to YS 4 stroke engines
• Fuel injected
• Convenient fuel pump adjustment
• High horsepower output with long service life

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.

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%.
