Has anyone tried or now own the new Rupe's LHR 21 or 15MM Mark V series Dual-Action polishers?
It looks like many of the design "flaws" or user-complaints of the Mark III (3) have been corrected or improved upon, including ventilation/over-heating, vibration, and the front cover.
One of the biggest is the new POLYSYNTHEC™ plastic gear drive to reduce vibration and weight,
I will not cut-and-paste the new specs from another competing detailing website, BUT AutoGeek currently does not offer it (yet?), SO you will have to Google it yourself and find out the what, how, and why the updated re-design improves it over the Mark III.
But as stated, I am looking comments by those of you Autopians who may have tried one of these polishers at a detailing show or actually bought and use it now for your polishing tasks and what your thoughts are on it.
Hey, maybe if you were "really nice" this year, Santa may just drop one off under your Christmas tree if you ask him (or whomever "Santa" is to you).
 
I have never gone long-throw, but when the cordless version of this came out a year or two ago I was all amped-up to try it, until TRC did a YouTube demonstration of it and it still stalled on a curved surface, so I just stuck with my Flex 3401.
 
I’ve only used the machines very briefly, most noticeable was smoothness.

I asked the guys who use them all day, every day and their preference is the corded Rupes Mark V.

Smooth, quiet and consistent power were the primary reasons mentioned.

So am I reading/interpreting the info above is that the detailers at Esoteric prefer the corded Mark V the most over other polishers available at their disposal for use?
 
Setec:
That stalling on curved surfaces seems to be a concern about battery (cordless) powered polishers ; not enough power OR is it just a design flaw/characteristic of dual-action (DA) polishers.
 
It's a DA/long stroke thing--I got my Flex 3401 back in 2007 or something and that's mostly what I use except for things like headlights or spot polishing where I use my old PC with 3-4" pads.

Yep! And when the spaces get tight the Rupes LHR75 Pneumatic is what they reach for.

As Setec mentioned, it’s a characteristic of the longer throw machines. When I first got my Rupes 15 it kinda drove me nuts with the stalling…would often get frustrated and switch to Flex 3401. Took an afternoon w an experienced Rupes guy to learn it (and a LOT of subsequent practice) before I began to enjoy it.

I always thought of it as getting through a locked door; the Forced Rotation is like kicking the door down, the long throw like picking the lock. Either way you’re in the room, just different approaches.
 
Well from the response above, here are my Captain Obvious questions:
1) WHY does this stalling happen with dual-action polishers, IE; what are the science & physics reasons for this?
2) HOW can this be overcome , IE; what DA techniques & methodologies does a user need to do and use?
Yeah, technical questions that are most likely difficult or impossible to describe in just words.
(You DO know, Captain Obvious, that there are probably You-Tube videos that can answer and visually "explain" this DA phenomenon.
Maybe so, but it is the reason I ask within this forum; this IS my detailing "YT" and I trust fellow Autopians more.)
And please, no smart-aleck response like, "Use a rotary ", although probably true!

I just sold one of my Rupes kits, with the other heading to Ebay this week.

I prefer the Porter Cable. I haven't been all too swayed by perceived/experienced increase in performance.

I think having a 7424xp and a 3401 set up again would fit me better. Back to basics.

Apologies to the OP.
