Congrats on an excellent choice in aircraft. As has been said, reliability is more important than absolute power. Good throttle response with no burbling or hiccups is also important. Built light, the MoJo can come in under 4 pounds and just about any modern 46 engine should be able to yank it around quite well at that weight. If you haven't already done so, visit www dot the****************** dot com and you will find a wealth of information on the MoJo and other cutting edge profiles. Be prepared, however, for all the rest of your planes to gather dust.
