Some aircraft such as the DHC-6 Twin Otter, have their throttles on the overhead panel:

Is there a reason that they are not on a center console between the pilot seats or mounted to the panel like on most airplanes?

It seems like it would be more comfortable for the pilot if he didn't have to reach up to change the power settings.
