Ok guys so I conducted a rudimentary but effective test of random orbit mode of the Makita 5000 as it relates to pad stalling, on flat surfaces and curved. I started with an LC CCS pad on it with the 5000 in free rotation mode, speed setting at 2. While on the flat surface of my dryer, I started the polisher and the pad did not spin at all. Bumped it up to speed 3, and again the pad was stalling under ONLY it's own weight - I was applying no pressure at all. Bumped up to speed 4 and of course the pad started to spin, but not very fast at all - lifting the head of the polisher up the pad regained speed - but who's going to do that while polishing! Speed 5 the pad spun very quickly and on a flat surface was hard to bog down. Now I thought to try this same test on the curved 'panel' of the dryer - shown here in the picture. On speed 4 or less, there was very little if any pad rotation as I rode the corner, and it regained speed once on the vertical panel of the dryer. On speed 5 the pad did maintain rotation around the curve albeit slower than while on a flat surface.
In direct drive mode, the pad rotated regardless of speed setting, and was not possible to bog down whether on a flat surface or curved, but that is to be expected in a direct drive unit.
I understand this was not a 100% scientific test but it did second what WRAPT said above - I was extremely unimpressed with the unit in free spin mode - bogging down under its own weight unless it was run on speed 4 or higher, and at speed 4 there was very little pad rotation.
If you are buying this to use solely as a direct drive unit, it's got power. If you are planning to use it extensively in free spin mode, get a GG6, BOSS15/21, Rupes etc. Makita missed the mark by a MILE in free spin mode as far as pad rotation goes. I ran the same test with my GG6 and on speed 1 (flat surface), and the rotation under its own weight was what the Makita needed speed 4 to match pad rotation.
PS when I swapped the CCS out for a LC ThinPro, pad rotation was slightly better but no where near what the GG6 could muster in pad rotation.
Sorry I couldn't video this tonight - wife was in no mood to be bothered with my 'tests' tonight - I knew better than to ask. LOl!
