Interesting comments about props. Brodak carries a new version of the Rev-Up 8x3, sometimes. The Rev-Ups seem to come and go from the website. I suppose they make batches periodically and then they sell out, and eventually they do it again.
The old TF 8 x 3 1/2 wood props are not uncommon on ebay. I got a bunch myself in a batch of wood props.
I've flown the MA 8x3 on an Enya 09 IV and it seemed OK, but I wasn't comparing it to wood.
