RE: IMAC Prop Selection????
I have decided to go with the 29X12 as well. It should be here by the end of the week. I too am using a sold backplate on my spinner (TruTurn). What are the updates you are referring to on the engine? Mine is less than a year old, so should be the latest and greatest. At least it hasn't given me any problems after 99 flights.
Now, if only the weather would warm a little - I just can't bring myself to go to the field with temps below freezing! Let you know how it turns out.
