Yes, bad things happen if your coil touches any metal other than the posts via the coil legs. You'll get a short.
+1 for the RM3

Seemed like time to re-visit this thread...
I ran the RM3 on my SL Grand for almost 3 months now. I left the air holes stock. - I experimented quite a bit with different coils... Even though I generally prefer a little cooler vape, I settled in on a pair of 1.1 ohm 29ga kanthal coils (6 wraps on a 2mm shaft). It just really, really produces vapor at .55 ohms.
This morning, I just decided it was rebuild day for my RM2s and my RM3. I've been running an RM2 on my 14500 mini for a couple of months or so, but the 14500 is indeed battery limited, so it has had a ~1.4 ohm-ish coil and even though the flavor is great and it produces OK vapor, it just isn't on an 18650... There's only so much it can do. It isn't a good comparison vs the RM3 on the Grand.
The other RM2 didn't need to be rebuilt, but I wanted to try a smaller diameter coil. I gave it a 1.1 ohm coil wrapped on the same shaft I use for the RM3 coils. And, I ran it all day today. -- Just as I thought before, the airflow is indiscernible -- I can not tell any difference in the draw on the RM2 and RM3. Also, just as I thought before, the flavor is equal. I just can't imagine any atty producing better flavor than these do. And, I just can't say one is better than the other.
There are differences though. The big one, of course, is the increased vapor production and hotter vapor from the dual coil RM3. It makes a denser cloud. This leads to all of those things we all know it leads to such as increased TH and increased juice consumption. The other big difference is drags per squonk... and that is subjective. In fact, it's almost completely subject to how one chooses to wick their coils. Though, the deck on the RM3 has a bit of a well so it tends to hold on to a little more juice than the RM2 deck. - Even though it's running duals and I use identicle wicks, the RM3 provides me a few extra drags per squonk. I like that a lot.
The glaring difference is ease of build. The RM2 is dead simple - easy - super-fast. I have aging eyes and my hands just aren't as steady as they were a few years ago. Mounting duals in a small space is tedious for me. I do not like that much at all... What keeps this from being a deal breaker for me is the simple fact it doesn't need to be done very often. In fact, I have yet to rebuild the RM3 because it *needed* to be rebuilt. I did quite a lot of experimenting and built it ~20 times so far, but even as an all day every day 6ml per day atty, this isn't something that will likely *need* to be done even once a month provided I don't go too crazy with the dry burns when cleaning my coils and re-wicking. So, due to that fact, I shouldn't complain so much.
Another noteworthy difference is the caps. I like the RM2 cap because the air hole is where the air hole is. Screw it on, and that's where it goes. All I have to do is be careful when mounting my coil to have the coil exactly where I want the air hole to match up. --> I like the RM3 cap because it's more forgiving as to where the airholes are
If I didn't place one of my coils right exactly where it should be, I can move the air holes a bit and accommodate my carelessness. .... .... .... The other thing about the RM2 cap is that it can tend to drag a dry wick around a little while spinning it on. Sometimes, the right side of a kgd wick just seems to grab it and spin with it. Then I have to put it back where it goes with a toothpick or whatnot before I give it its first squonk. The push on cap on the RM3 does not do that. -- I think I prefer the RM3 cap.
There's no going wrong with either an RM2 or an RM3. There may be details I prefer about this one or that one, but there's just no going wrong with either. - What I foresee for myself: I currently own a 14500 mini, a VVW, and a Grand.
The 14500 will keep an RM2 because it pretty much has to. I don't think there's any acceptable driving of a dual coil no matter the ohms with a 14500.
The VVW will also keep an RM2 because a single coil above 1.2 ohms is the right device for that application... and because that's what I bought my Brass RM2 for to begin with.
The Grand will keep the RM3... and when the Grands start coming with the new SS 510 and I just can't resist buying another grand, that one will very likely also get an RM3 (unless, of course, I also feel a strong desire to satisfy my curiosity about the LP Grands and all of the bigger bore attys that fit them... never know)
So, Thanks, Papa_Lazarou! I probably wouldn't have tried the RM3 without this thread. I'm glad I did.

OK, I am a convert. Took some getting used to, but my nuppin is getting neglected now compared to the rm3
Six - regarding the RM2 cap lining up with your coil you can adjust where the hole ends up. Place one of your orings that you use inside the juice well and stretch it over the threads of the bottom of the atty. That way when you screw the cap back on you have some extra resistence to line up the cap exactly where you want it to be vs. worrying about placing the coil to where the hole ends up. The placement of the coil is critical as you know so it's better to have the coil inplace to allow for airflow over and under the coil and correct placement at side of drainhole and close to edge. Once you have that placement the oring on the base will allow less or more turns of the top cap to align with your coil.
That is wrong on so many levels... I think the Nuppin' was the best atty of 2014 by a huge margin...
Or use sand paper or a file on the cap of the RM2, as you shave off some, the cap will slowly rotate around the RM2 base in a clock wise direction when screwed on.
Lay the paper or file flat and run the cap over it keeping the cap level. I've done this to all of mine so that the air hole is dead center between the posts without using a o ring. When I got them stock the air hole was about 7:30 if dead center between the post was at 6. So I shave them enough to rotate the cap almost 360 degrees to 6 o clock.

Mac Gyver would be proud!!
Same here. For low power single coil the RM3 is my overall favorite of all the small chamber atties.
I wonder if superX can do a dual coil build video? 
Search youtube for the A6 atty (it is the RM3) and you'll find some building videos. Its really not bad to build a dual setup on it. Good luck - hope you enjoy yours as much as I do mine!

Does anyone have a handle on the A6 (RM3) O-ring sizes ?
Best I come up with when they stop wriggling around is - 13mmOD/11mmID/1mmthick.
Measured the empty O-ring groove with digital calipers at 11.3mm.
Thanks.

SOS. Ever since they worked on the forum as I am going from page to page it eventually will tell me I can't do it again and I can't read all of the posts....am I the only one that the RM3 will not make contact on my REO I know it is that....REO is working with RM2, with the RM3 nothing. I did do a dual coil build coming in around .84 and I'm real proud...but I wanna use it now! Thanks.

It was the pin, pushed the middle pin down and it's making contact now. Thanks for the reply. Gonna see how she works now

510 pin "screw" slot is for decoration, the one-piece centre post and 510 connecter pin, is a tight push fit from the top down, as TraceyS found.
