Hello Paul,
While making some decisions about how to wire my starter circuit, I had

a

question asked to me by another builder.  I didn't know the answer.

He asked if there was a major electrical failure that caused a loss of

power

to Tracy's EI / EFI, would the prop / RD1-B Redrive continue to spin in

the

air stream (thus turning the e-shaft) until I can switch over to the

isolated

"Essential Bus" to reestablish electrical power.  If the engine

continues to

turn over, it should restart immediately after reestablishing electrical
power.  If not, I will need to power the starter off of the isolated
"Essential Bus" in order to restart.

Any info would be very helpful !!!
I may need to ask Tracy directly though.

Thanks,
Don

I think we need to ask Tracy that question. Tracy?

Having had the engine quit at altitude (Must remember to switch tanks before
the selected one goes dry), the Ross drive and prop continued to rotate the
engine at 85 mph IAS (my selected best glide speed as I frantically tried to
sort out what the problem was).  After approx 60 seconds I had the tanks
switched and boost pump on feeding fuel back into the system.  The engine
immediatly came back to life (as did my heart).  Tracy's gear box will
continue to engage the engine - whether the prop will rotate the engine is
somewhat dependent on your prop and airspeed.
