Clearly a newb question. in regards to Aerotech RMS 24/40 and 24/60 hardware. If I buy the 24/60 hardware I can use all the 24 40 kits in it? I think there are spacers I have to use? just now looking at the reloadables. Don’t ya just hate not knowing stuff. Haha.
Confused at RMS hardware

The 24mm cases don't mix and match at all.
There are no spacers to adapt 24/40 reloads to the 24/60 case. You will need to get both cases to fly reloads for both.
Spacers only come into play with high power and high power-style cases and reloads 29 mm and bigger.

All that being said - if you are choosing between the two, get the 24/40. Much more versatile case with a huge number of reloads for it. Personally, I'd say the 24/40 and the 29/40-120 are must have cases for mid power flyers.
While I agree on picking the 24/40 over the 24/60, for me it's an economics choice. Yeah, there were 8 (now there's only 5 made all the time) loads for the 24/40, but I don't think the Ds make sense and tiny Blue Thunder underwhelms me. The 24/60 has great red, black, and white options but the trouble is the cost: [at retail,] $18/F motor vs $14.33/F motor for very similar impulse in the 24/40.
The F24W in the 24/40 case is my favorite small mid-power motor.
The 24/60 red is a disappointment. Extremely brief and small. Needs more juice.
Eh, I like it myself. It's definitely more visible than the F27R, and it's your only red option at 24mm.

I have four of the 24/40's and two of the 24/60's so that I can do clustering. The 24/60 has a much more robust design (larger less delicate threads).

The F24W seems to be a sweet spot of bang for the buck. Especially with Quest E35s being at ACSupply, anything less in the 24/40 seems silly. F39s on occasion. In my mind, the 24/60 is basically an F35.
Also, just to be that guy (see avatar), the question in the OP was asked and answered a few weeks ago and a search should have easily found it.

I'd personally get both motors. The RMS 24/40 has several great loads, my favorite are the D15, E18, and F24. Don't knock the 24/60 till you try it. The F35 is an amazing load, and I personally like it better than the F24. The F62 is a beast with its dark smoke!
I really wish Aerotech came out with their 24/80 and 24/120, I actually got to hold a prototype 24/120 motor. With CTI requiring hazmat, and the loads I want being hard to get.. that's just a missed opportunity.
I have a rocket where literally the CTI G65 is the only load I can fly it with, because all the other loads are HPR, cant fly them where I fly, and the only vendor that I buy from that has G65's, doesn't have G54's, but the other one does... but I am not going do two hazmat orders.... ugh...

I think the solution going forward is to not build MPR rockets with 24mm motor mounts, right?

Actually the rocket is a two stage rocket built to fly on 27mm motors. It flew on FSI F100's. I want to fly it again, and my plan is to fly it with both stages joined but on a single G.I think the solution going forward is to not build MPR rockets with 24mm motor mounts, right?

That would be a great case to have! I have all the CTI 24 cases but seldom fly them due to hazmat fees. The 24mm G reloads are awesome! There are a lot preexisting kits with 24mm mounts. Perhaps this is a topic for the Aerotech mfg thread.
Once I burn through my huge stockpile of E28 reloads, I'll likely sell a few of my 24/40 cases and mostly fly the brilliant, economical and case-not-risking E35 instead. I do like the F39 and will likely continue to fly it some, but I don't know I need five cases for it.
+1 ( if my vote counts ) for longer, higher Total Impulse 24mm RMS Casings and reloads so I can fly the Blue Raven with them.

I use the D15 quite a bit. It has a very aggressive initial "punch", and can get a decent launch speed for heavier models that can't fly on any other D. So I use it on smaller fields, and also sometimes for a low altitude 1st flight of a new rocket.

Have you tried the D22 Q-Jet? Seems like similar punch for less money and a more fun propellant.
I use quite a few D22's. But OpenRocket consistently shows higher launch rod speed for the D15, mostly because it has higher thrust for that 1st 0.1 sec interval. For most rockets, it's a moot point, but I have a few that are marginal on the D22. In general, I'll use the D22 if I'm too lazy to load up the D15

That's been discussed. Hazmat and availability is a bummer
I kind of did, but I've heard that product availability is currently problematic. Also, although I'm not sure about 24mm, the CTI products are all Hazmat.
Hans.
the 24mm are hazmat , see: https://www.csrocketry.com/rocket-motors/cesaroni/motors/pro-24/3g-reloads.html

I've always wondered why that is. Is it the Pyrodex pellet that's used to enhance the ignitor's burst for ignition?

They are not manufactured in the USA and the manufacturer never went through the process of getting them approved for USPS shipping exemption. Not all the loads have the bp pellet.
It is also shipped with an E-match type starter

That is correct
And the price for 2 single use Quest
