I disagree. This plane is mainly for hovering. If you put an Irvine .39 on the magic, you would have to use full throttle stick movement in order to hover due to less power. If you use and larger engine with low pitch prop, such as the Irvine .53 or Magnum .52, you can set it up so that you can hover at half throttle and have finer control over the plane while in a hover because you won't need to move the stick as far forward.
