I am in the process of buying an engine. I am told by TCM, that the FADEC is

only available in 24V and they are not supporting a 12V system. I have

designed my aircraft for 12V, however other than some lights and my

Hydraulic pump motor and pressurization outflow valve, everything else will

work on 12/32V. Is there an easy way to convert the 24V to 12V for the

hydraulic pump and outflow valve? The heavy user is the Hydraulic motor,

calling for a 12V/50A fused supply. Any thoughts on doing a 24-12V high amp

conversion would be appreciated.

   Dual voltage band-aids are seldom very elegant.

   Suggest you go fully 24v. The pump motor is easy

   to swap out. How much current does the outflow

   valve use. If on the order of 1A or less, a simple

   series down-regulator is not too ugly.
