Wolf Predator 1.8 Info Needed
I am looking at a Wolf Predator 1.8 to put in my 1/4 scale 231EX. Does anyone know anything about these engines? Here is the link to their website so that you can get the specs.

I am looking for someone that has actually put this engine in a plane. Please reply. Thanks

Wolf Predator 1.8 Info Needed
A fellow brought a new Wolf 3.2 to our club meeting last night. Looks OK. I don't know who's cylinder and piston they use, but they cast their own crankcase. It uses a crankshaft setup similar to the Taurus with a rear bearing. Probably a chainsaw crankshaft. A sideport engine. Comes with the CH syncrospark ignition and Bisson Pitts muffler. I'll let you know how it runs when he stuffs it into his plane.

Snowfly, for about $10 less money, I'd go with the ZDZ 40RV-L. It's 2.4 cubic inches as opposed to the Predator's 1.8 cubic inches and makes a LOT more power than the Predator. Both engines, with ignition, weigh about 3.25 pounds.
The February, 2002 issue of Flying Models magazine has a story on the Midwest Extra 300XS (80" wingspan) that they powered with a Predator. They said that it ran well with no problems.
A gasoline 1.80 puts out similar power to a glow 1.20 to 1.40 two stroke engine, but it weighs over a pound heavier.
I'd go with the ZDZ, or maybe a BME 44.

Look at WEBB site for the 1.8 Predator engines. ZDZ40 data is easy to find. Thanks , john - P.S. Is there any more data on the 1.8 -like actual experience.

I have a Wolf Stinger 1.5 on glow. Got a really good deal at a swap so price was not a issue. On the sixth 10 oz tank on break in I had a 7400 rpm reading with a 18/8 Zinger prop. Hand starts, a pretty!! good engine
