I need some feed back from the pilots
 out there that might be using the 555 system.
 Here is the leaning pot I found that will solder
 to the mother board and poke through the instrument panel.
 Also the switches I plan to use.


 Another option is to let the builder choose the switches
 and pots and mount them remotely from the mother board.
 The downside is more skilled labor required to wire them
 to the mother board. There will be at least one pot and
 one switch for every two injectors. That way the mixture
 can be adjusted separately for each rotor based on the EGT.

 What do you all think?

 I am also looking for somebody
 building an EFI engine that would like to try this
 prototype system on the ground for free. Let me know
 where so I can show up when you are ready to test.

 You will need to buy a wide band mixture monitor.

Paul,
I vote for remote mount.  Planes are so different.

Hook it to the third lever on the throttle quadrant where the mixture
control would ordinarily be. milo
