I use the Saito 100 on mine. It's the finest plane I have and that engine makes it scream! The 120 seems like a little power overkill to me, but nothing wrong with that. Here is a pic of mine. Also, let me say that this pic was taken right after I crashed it. I was running to lean and the vent line melted off of the muffler nipple. Lost pressure in the tank and killed the engine. The plane was about 50 feet up so I barely had enough time to get the nose up before it slammed into the ground. I broke the spinner, cowl, and tore out the landing gear. Nothing else. It's almost back together after just a few hours work. I think that says a lot about the quality and durability of the VF Edge. Also, I put the engine on my test stand and it runs just as good as when I first got it. Saito's are really good engines. [8D]
