Flex 3401 vs rupes 21 mark 2

The 21 MKII has no competitor from any other DA, closest competitor in power and speed of correction would be a Flex PE-14 rotary. The 3401 is more around an LHR15ES. If you have absolutely no technique stick to a 3401, if you a pro, get a Rupes.

Um, Flex has been around much longer than Rupes. But hey, if you can't handle the power of a forced rotation Flex, stick with a Rupes! Lol!

That's true.

Flex 1922

Rupes 1947.

Do you own both a 3401 and a MKII 21? If not,yours and others advice here are null and void. The 21 MKII NOT ONLY TAMES THE " BEAST", IT DESTROYS IT ON ALL COUNTS!

Seriously can't see the point of ancient, outdated tech being compared to far superior technology and the old stuff being defended by people who don't embrace new technology- this is clear as night and day. I'm not the only one who notices the ignorance and lies constantly being given by certain individuals. Those that are stating a 3401 to be on par a MKII or more powerful should be living on the moon.

No I do not own a Rupes 21 due to the fact that I never was really all that impressed with the mini or the 21ES that I do own. I'm sorry that you can't handle the fact that many people prefer the Flex line of tools over Rupes but to call others ignorant or claim that they are dishonest based on their choice / opinion is an asshat move on your part and only makes you look immature. And comparing a rotary to a DA is quite silly and it shows that you yourself do not know much about technique or what being a professional entails.

Flex 3401:
Power output: 590 watts
Orbit rate: 3600-9600

Rupes 21 MK2
Power output: 500 watts
Orbit rate: 2500-4700

Hmmm, the Rupes is more powerful? "Certain individuals" need to stop "giving lies!"

Coming from someone who doesn't own or have experience with a 21 MKII, yeah you definitely are a liar along with another ignorant poster or two who will soon come in with more lies.
 
This thread mainly counts as full timers no pun intended and no insult to anyone.Everyone has there preference on different machines,rupes and flex are great machines at the end of the day it's about doing excellent work and getting paid.But I can assure you that the flex is better at getting the job done quickly.That deosnt make rupes a bad tool.So to say that if we are not using rupes we should pack it in and move to the moon is out of character.If you have ample time as a hobbyist or part timer you are not under time constraints.Example faded car or small faded camper what will perform better and quicker and that answer would be flex.Ive had the pleasure and opportunity to use all the latest machines that are out there on the market,so this paragraph is backed by that with true hands on experience on all different paint systems and cool cars and oxidized boats and rv.So there is no need to say this is in accurate info and also null and void.Buy what you want and be happy.

People like you who harbor the same attitude are the plague of this country. Oh wait, you're in SA. Please stay there!

Agree buy what you want or fits your needs.No reason at all to put members down its silly and proves nothing.
 
I have to imagine the operator, and their selection of abrasives and pads are going to make a significant impact on the performance on any tool.

Agree but I would rather do less passes as possible with my flex= less time buffing= more cars done per week= more money in my pocket.you absolutely would not be able to produce results quicker and faster results on aircraft or sanded boats.But again that's my opinion and it deosnt mean squat.Buy what you want and be happy.

Exactly. Someone experienced, and well versed with the 3401 is going to get more out of it than someone dedicated to using another tool.

This is incorrect compared to the industry standard. Flex counts their OPM different. The 3401 actually spins at 4800 OPM on speed 6. I GUARANTEE this. A GG 6" spins faster than a 3401, but that's with NO LOAD. That's what makes the 3401 unique, as it's the only DA that won't slow down when pressure is applied. Even if I didn't know this, on speed 6, the 3401 never struck me as spinning at 9600 OPM. That is A LOT! Totally made sense once KB told me the 3401 only spins at 4800 OPM full throttle.

i sold my flex 3401 vrg thinking to by rupess 21,i think that i made mastake....flex is flex
talinas make pizza

I mistakenly got rid of mine too. It truly had a place in the tool chest.

I went through a "one and done" phase, where historically I like many options. I'll eventually be adding the Rupes 21, Flex PE-14 (again, mistakenly sold mine), and the 3401.

Yep 4800 opm only at speed 6! Plus with only an 8mm orbit thats why its so slow in correction and old tech. Does it get the job done? Yes, just like a PC does.

Wattages doesnt mean everything. Chinese Rupes knock offs have 900w and so does Boss and yet MK2 is supposed to be more powerfull. With your logic Griots Boss Destroys Rupes Mk2 and Flex. Rupes is just very efficent. Today i again removed p1500 sanding marks from metallic blue bmw hood with Rupes 21 Mk2 and mf pad with one section pass of 4 overlaps. Only 2 steps from p1500 to perfect.
 
The Rupes is like a woman, you have to treat it right and finesse it all the time or it'll stop working for you and everyone else will say it's your fault. I have multiple rupes machines and only reach for my mini to do intricate areas because Flex refuses to make a mini forced rotation. With that said, I always reach for one of my flex machines!

Lol this post make me laugh :laughing:

Not sure where you heard that at, but my G21 is noticeably more powerful than my MK2....and my MK2 does not correct faster than my G21. I have both obviously as well as a 3401.

I was in the same boat as the OP quite awhile ago and was sick of all the misinformation so I just went ahead and bought all the machines to try myself, ended up keeping all of them.
