I wanted some info on both of those engines as well. However, because they have their own self contained ignition and do not use nicads, they do not get a lot of respect around here. This crowd only likes light engines that need nicad powered ignitions. Dare you mention a Fuji or Zenoah and they will just tell you to get a BME, ZDZ, DA, or the countless others that need nicads to power the ignition. I guess they tend to be lighter overall and give a better power to weight ratio with out any heavy magneto ignition installed.

However, Zenoah and Fuji's I believe are quality engines. I will get one in the future.
