The non-eco enertia 19p is a smaller diameter 14" if you want top speed. I do like the handling and low/mid range the mirage or rev4 better than the enertia. The old mirage (non mirage plus) are pretty fast too.

Old Mirage A40-41 (not the a45-46) has the thinner blades and is lighter=faster & better top speed http://www.thehulltruth.com/images/s...p/thumbsup.gif

Jeeze, would you guys just R-E-L-A-X. Anything over 17 knots blows the wine out of your solo cup and you gotta keep backtracking to get hats! You only have so many "frams" in any engine before it scatters and so many days out on 3/5 of Space Ship Earth that's covered with H2O before something breaks on you healthwise. It's hard to take it all in well, at a mile a minute. Go easy, prosper, live long and enjoy the trip!

This is the best advice in this thread. I'm reading this while attached to IV.

Roger that, Tim! Hang in there Bigshrimpin.
