				Hi Mike,
 
 I don't know of anyone who has installed an 80 hp engine in an Xl, 
 but the drawings call for that as the minimum engine for the plane.
 
 Using such a small engine will impact a lot more than just the top 
 speed.  It will seriously limit the climb rate and increase the 
 takeoff distance.
 
 Good luck,
 
 Paul

				When I was up at the Zenith factory, I asked if I could run an areovee or other 80ish horsepower engine in the XL...  I was told that I would be very unhappy with the airplane.
 
 They didn't say I could not do it, just like Paul points out, it will fly with an 80 horse, but the margin of error is going to be slim at best.  I would not want to be anywhere near short, or have to do a go around at the last second.

				cheers guys
 i think i will stick to the 100 horses  it was a good deal on the 80 hp 
 not to worry will have to wait until one comes up in uk at a good price as i cant get  one from USA because of the araes that they sell too, still a good exchange rate uk prices are to high
 
 any way thanks  again

				I am just starting on my 701 and have plenty of time before choosing  
 an engine.  But I know the engine I am waiting for,  it is a single  
 rotor rotary engine  based on the Mazda two rotor automobile engine  
 many of which are flying successfully at this time.  The single rotor  
 promises around 110-120 hp at 180 lbs firewall forward.  One is  
 running on a test stand.  A lot of work remains to be done.     It is  
 worth waiting for.   The stardard rotary conversion is too heavy and  
 too powerful for any Zenith aircraft but the single rotor with  
 aluminum end housings  is a perfect fit.  Jerry

				Jerry.
  
 I looked into the rotary about 4 years ago, found one ready to go, tested on the stand for a lot of hours.  But the weight was about 225.  Must not of had the aluminum end housings.
  
 There was a article in Sport Pilot a few months ago on three RVs, one of which had a rotary in it.  I remember that the fuel burn was about 15% more than any thing else with the same HP.
  
 I would be real interested in what you come up with.
