JW,
Those are some very good rpm numbers! It appears that your fuel and prop combination works well with the JETT 76l. I'll switch out my Zinger Pro 14x4 for an APC 14x4w and see if my rpm numbers increase. I think it will because APC props are reported to be more efficient. I can say that I've never had an icing problem here in Texas! Boy, that sure looks coooooooooold.
