John No. Although the RX-8 throttle controller will be redundant, my strategy for fail-safe on this item is to have a separate (small) throttle body for heated & filtered air which will allow enough power to sustain level flight as well as taxi power. The main air inlet will be unheated and unfiltered.

Greg Changed my mind again on oil cooler. Engine room on the RV-8 is coming out so nice & sanitary that I don't want to clutter it up with the oil accumulator that I bought to damp out the pressure pulses that could kill the evap core cooler. Also getting a little more conservative (chicken) as I get older. So Rusty, was that a fluidyne cooler on your -3? What model? Looked real good. Finished my evaluation on the RX-8 fly-by-wire throttle body and still plan to use it. It is not as simple to use as I had hoped and will require a custom controller to make it work. I'll make them available to others who want to use this part.
