A little advice needed.

[Andy Greene]

I'm considering purchasing an AT RMS 29/40-120 for use in several of my mid power rockets,
2.6 M/C Mozzie
MC Hawk
Pro Series Argent
MC Bomark

Am I barking up the right tree on the case itself ?

They are great for mid power. I have several. CTI is easier, but once you know how to build AT, they are no big deal.

 

[Davidtmp]

I'd say your fine. Reloads are a little cheaper than the CTI's, good performance. I have a few G64 that have been around for a while, after that I'm going to look into getting a few reds and greens for that case, as well as those G138's people rave about when I get thru my Lvl 1.

I'll skip sharing my far-too-many failures with AT motors and casings, but will add two points that you might find useful:

1) The hardest thing about flying Cesaroni motors is pulling the metal staples out of the cardboard packaging. Everything else is simple and quick. With AT motors, you get to build it (O-rings, grease, etc.) and that is not a lot of fun when it's cold. CTI motors are more expensive, though...

2) The one thing I WISH I'd fully realized when I bought my first 29/40-120 is that it's fairly limited to a handful of motors, and if you want to go bigger (and you will), you'll be buying another case. With the Cesaroni model, you can buy a 3-grain 29mm case and two spacers, and fly everything from the same case. (Same for the 4/5/6-grain motors in the 29mm 6-grain case, and you'll be using those same two spacers across both cases. Same for the 38mm motors -- 2 cases and 2 spacers gives you access to every motor except the -XL ones.)

Some folks like to build motors, but for me the sparse time I get on any field due to weather and crop schedules or other obligations makes that field time extremely precious. I don't want to spend it putting motors together, so I predominantly fly Cesaroni for that reason alone.

I looked at the CTI and they are very nice- I'm okay with the additional cost of the case , but the cost of the reloads kinda defeats getting away from SU motors if you shop around and get em on sale. That's really was the main reason I was considering a RMS , I just want to fly more- lol .

Scott, I see the advantage of NOT building motors at the field, I agree. And I guess the CTI's ARE still cheaper than SU's. Their engine classes seem to be what is spooking me a bit I guess. I'm guessing the Super Starter kit would more than cover me ???

I have 5-6 cases for the 29 40-120. Load at home. Fly them. Clean and reload them at home.

 

[Green Jello]

That is the exact one I got for my first 29mm case after researching it here and getting everyone's opinions. It has a great range of reloads for your first MPR case.

Kinda kills the cost savings at 45+ a case x 6 :y:

Thanks Dave- I'm going to go that way- I like the fact it opens a ton of options. Now I just need to figure out the CTI numbers and what is close to what I'm used too - AND of course talk the wife into the extra 50 bucks- I already had her sold on the AT :tongue:

Just practice assembling in the dark in front of a fan, dipping your hands in ice water and drying then between steps, and you will be able to assemble a motor anytime you are even allowed to fly, in the field.

Depends how much you fly. If you collection slowly grows buying one here and there with an order of reloads. I would at least want 2 of any hardware in case you lose one. Could mean you are done for the day.

I have three 29/40-120 cases and I never paid more than $20 for any of them. It took me several years but I just watched the Yard Sale section and eBay..
I unlike Scott have had few problems with my 29/40-120 cases but I don't use the supplied BP. I had several flights that failed to eject on AT motors. The BP burned but failed to produce sufficient gas to pop the nose cone. This problem may have been solved but I don't intend to experiment.
That said I am going to get some CTI 29s this year.

The AT 29/40-120 is absolutely invaluable to the mid power flyer! LOVE this case! Great range of motors from E-G impulse, and easy to assemble the cheap reloads! Definitely shop around on ebay to see if you can find a used one pretty cheap. I've never had problems with my hobbyline AT case, and I've been using it since I started flying again about 10 years ago. LOVE this case. And my AT 24/40 case. Great for those bigger Estes rockets that need a little more oomph (like the Phoenix, Executioner, Big Daddy, Mean Machine...you get the idea...lol)

One thing you may want to consider is the cost of shipping CTI reloads and the availability at your launches. All of the 29mm CTI has a hazmat shipping charge. where few and far between of the 29mm AT reloads require hazmat shipping, $27 bucks of extra shipping can SUCK. And CTI is not as available (at our local launches) as AT has been.

Really, for the mid-power range - especially if you fly your own field (i.e. not a vendor attended club event) - the AT hobbyline cases are a bargain and a half. It was fun to put them together when I was just starting; now it's a pain in the...yeah. Still, even though I just ordered a whole slew of stuff for CTI at an nearly unheard-of 30% off list, I still couldn't bring myself to buy any 29mm 1 grain reloads, and the only 24mm reloads I got were the Vmax that have no analog in the AT world.

With AT, you not only can find them at 33-40% off list every day, but you don't have to pay real hazmat on them - just ship regular old ground. Where else are you going to find a full E for $5.60 (vs. $12.80 for the equiv Ns in a CTI), a small F for $6.50 (vs $16 for CTI), or a medium G for $10 (vs $18 for CTI). It keeps it as more of a hobby and less of an obsession. At $8-10 a flight, you make back the price of a case very, very quickly. I've built up my stash to 3 29mm cases and either 2 or 3 24mm (I think I may have lost one a while ago).

 

[DizWolf]

I love my 29 40-120 cases. I'm still at the stage I like building them. I've got two and plan to buy at least a couple more. I've also got two CTI 1G cases in 29mm. Primarily to use in my 29mm cluster, though I haven't put in a CTI order lately so haven't tried those out. Kind of excited to try the F36BS in there.

 

[chadrog]

The 29 40-120 are my most used cases, love them! The hole in the bottom of the ejection well of one of them is about two and a half times bigger than when it was new - I wonder if that will ever become an issue?

 

[Andy Greene]

Thanks the in-put once again guys. I put a WTB in the for sale.
