1-Year Update:
The RedMax EBZ8500RH blew very strong out of the box, just under full throttle. Personal opinion: it seems like a Stihl BR600 Magnum, but with much more air volume (and being somewhat heavier, not as good on gas, and way louder). If you remember, I detailed a specific need for power to rip & launch wet oak leaves into wooded land and wanted more....and the smaller pipe I'd ordered wasn't cutting it.
I added one extension pipe and changed the nozzle to the scraper--that did it, but it's a real bear on the arm. Serious power, incomparable power, but it's a monster. Lawn-bombs away! (Yeah, it launches them with a vengeance.)
To open this year the RedMax two-stroke started in seven pulls, where as the Stihl 4-stroke started in two, and wanted to start in one. The Redmax ran a bit rough for 1/8 tank but was perfect after that, the Stihl ran perfect from the start. The RedMax isn't Brad Snelling's silky smooth-running machine, rather it's a troll with a spiked club that's going to do some damage. The only real issue is if the thumb-throttle is pushed a bit too far forward it dutifully shuts the unit down, and won't restart even with a quick flick back and plenty of RPM--off is "off," which requires a dismount and pull-start. My extended tube makes the re-mount a bit of a proposition, but it's doable.
My previous impressions throughout this thread (last year about the same time, also the best price I could find and free shipping) were accurate, tube thickness and all. I really like the RedMax for the power, but the Stihl BR600 Magnum is an excellent choice for normal jobs. Although, tell you what, with the normal nozzle the RedMax takes a mountain of leaves and re-plants them wherever you want in no time, no time at all.
