I have to agree with Ralph, Silversurfer, and razrback.
To tell you the truth I have never had a bad engine from any of the top manufacturers.
3W,DA,ZDZ,Zenoah,etc all make very good engines. I and a few others have choose to go with one that is a little lighter and on the cutting edge.
You aren't using a 286 processor in your computer any more are you???

bird-0f-prey, I wish I was getting kickbacks, I pay full boat just as everyone else does.

AndresAM, I have commented on BME quite a bit, because I have used them (others too) and I can give an honest opinion. You will also notice I have NEVER in any of my posts degraded any manufacturer and believe me they ALL have there weak and strong points. I have recommended other engines for other applications, but in the 100cc class I tend to lean to wards the 115 at this time.

One more thing, razrback ain't BS'ing when he say he has owned and flown a lot of plane/engine combinations out there. He changes planes like I change my under wear
