UL POWER FWF for the Zodiac CH 601XL/650 and STOL CH 750.

Picture

UL-Power Engines have been developed specifically for use in light aircraft and are manufactured to the highest standards with a  fully electronic ignition and multi-point fuel injection (FADEC) system as standard equipment. These truly modern engines also feature multi-point electronic ignition, excellent power-to-weight ratio, and high fuel efficiency in a conventional configuration: Air-cooled, direct drive, horizontally opposed four-cylinder.


Firewall Forward Packages (FWF)*

Zenith Aircraft Co. developed our complete Firewall Forward (FWF) packages for the UL Power engine series. You will notice that the price of these FWF Packages are low compared to many other FWF packages. This is because 
many traditional FWF items and accessories are actually supplied by UL-power and we include these items with the engine rather than as part of the accompanying FWF Package.
(Important: If you do not plan to order your UL-Power engine from Zenair or Zenith Aircraft, read the additional "Warning" and list below!) 
The video at right provides a closer look at the 130-hp UL350iS engine installed on the sleek CH650.

Note that
the STOL CH 750 and the Zodiac CH 601XL/650 use the same firewalls, so the FWF kits are the same except for the engine mount.  

Price of UL350iS FWF/7........... $6,995.00 US (now with Sensenich prop)
Price of UL350iS FWF/6........... $6,945.00 US (now with Sensenich prop)

Price of UL260i FWF/7.............. $6,095.00 US (No cowling - see note)
Price of UL260i FWF/6.............. $6,045.00 US (No cowling - see note)
Click here for a sample list of the items typically included in our standard UL-350iS FWF Package (subject to change).     

Note: Our FWF Package for the UL-260 engine series
does not currently include the engine cowling; it does, however, include a WhirlWind propeller.

UL-Power Engines*

You can also order your UL-Power engine through Zenith Aircraft along with your FWF Package, or separately. Please note that since UL Power engines are imported from Europe (like the Rotax), prices fluctuate on a regular basis due to varying currency exchange.

____________________________________________________________________________________________

​WARNING:  If you order a UL-Power FWF Package from Zenair/Zenith but NOT the engine, you will likely be missing a number of important components to install your engine. These components are supplied WITH the engine when you order a UL-Power engine from Zenair/Zenith. If ordering your engine elsewhere (i.e. a UL-Power dealer), make sure to also order the following UL-Power components (see list at right):
