-    Multipoint electronic fuel injection with automatic compensation for altitude and temperature
-    Redundant dual electronic ignition
-    High fuel efficiency
-    Excellent power to weight ratio

These new engine models can be ordered now.

We are proud to confirm the first orders for the UL520i and UL520iS are coming in.  “I am pleased to announce the receipt of our first order for the new engine.”  Said Robert Helms, General Manager of UL Power North America.  “Renegade Light Sport plans to offer the UL520i at 180HP as an option on the beautiful Comet biplane which was previously powered by either 100 or 118HP engines.”

“Several other manufacturers are considering the new engines.” Said Robert Helms.  “The thrust to weight ratio is appealing to the designers of many aircraft.  Whether you are focused on short take-off, high economy, or high speed, the UL520i & UL520iS offer incredible performance, reduced weight, advanced technology and are competitively priced with other engines of the same horsepower.  We are also working with individual aircraft owners to develop firewall-forward kits for models not otherwise supported by their respective manufacturers.”
