Which Reload Brand Should I Buy???

[rocketman]

I was originally going to buy congreve 29mm casings, closures, etc. However, after contacting them, I now know that they won't have any in until after christmas (wait? me? :dark.
So, I'm going to buy a different 29mm case brand with closures. So, the big question (can of worms?) is: Which Brand?
I want one which is as cheap as possible, reliable too, and with plenty of choice of reloads.
Suggestions?

Remember, I'm uk based.

I'm not sure about in the UK, but here's my take from the States:

If you want easier assembly, more exact delays, slightly cheaper cases, more HPR choices, adjustable delays, and skidmarks, go for Cesaroni Pro29.

If you want more choices of what vendor to buy from, cheaper reloads, more MPR choices, 29mm Es, MPR Redlines, and the fun (IMHO) of building your own motor, then choose Aerotech.

With Cesaroni, you're goign to pay perhaps 20-30% more for motors, in exchange for insert-and-fly reloads that don't require much assembly.

I don't have any knowledge about the others (AMW, Loki, Kosdon, etc) or hybrids and what options they have in the 29mm size.

I personally fly AT because I'm on a budget and for what I fly AT is cheaper, but I want a Pro29-2G case, just for the new G80 sparky.

Are you looking more for F-G size, H-I size, or both?

D-F - Aerotech
G+ - Cesaroni

Thats just my thoughts.

AT is cheaper but more complicated.
If you rely on motor ejection, chose CTI.

 

[cjl]

I like both AT and CTI, and fly both regularly.

 

[mkadams001]

I use Aerotech mostly because that is what I have been using for several years. I would like to try CTI but the reload cost is a few dollars more than AT. I enjoy building the motor and I don't find it very complicated. Considering that you want stuff right away I would research what is the most available to you in your area or from your online vendors.

 

[Donaldsrockets]

I prefer AT myself. I've flown lots and lots of AT motors without incident. Sure, I've had some delays that ran a bit short but given the nature of pyrotechnic delays, that can occasionally happen.

But overall, they're pretty reliable.

I also like the fact that the loads are cheaper and I actually enjoy assembling the motors. Post flight clean up is not that bad IF you don't wait too long.

I do wish AT would make sparkies but I don't think they have any plans to do so. For that, there's always CTI.

They just certified a new Pro29 2 grain G80 Skid that I would absolutely love to try.

Thanks for the fast replys everyone!
Looking at rocketstore, it seems that pro29 reloads aren't yet available in the uk!
However, I still have two further questions:
1. What does "1 grain case" "two grain case" etc. mean? All i can tell is that each one seems to be bigger than the last, and more expensive!
2. rocketstore sell rouse tech casings, instead of AT ones. Which bits exactly do I have to buy (to have a complete, launch-ready motor) link to what I mean here:

Hi rocketman,

I am a UK flyer with experience of Aerotech, Cesaroni and Congreve rocket motors.

If you are looking to buy some 29mm motors before the end of the year then Aerotech will be your best choice.

Do you have any ideas what size rockets or motors you are looking to fly? If you are looking to progress from Estes motors then it might be worth having a look at the 29mm Hobby Line casing. This one casing is suitable for 6 different motors; E16, E23, F22, F40, F52 & G64

Other reloads are manufactured by Aerotech for this casing, but are not currently certified / classified for sale in the UK.

Where you see motors or casings measured in grains this refers to how many pieces of propellant (grains) make up the motor. A 2 grain motor will typically be twice as powerful as a 1 grain motor given the same propellant and diameter, etc...

Regards,

Rob House

There are also G53FJ (-5, -7, -10), G71R (-4, -7, -10), and G76G (-4, -7, -10) loads for the AT 29/40-120 hobby case as well.

To the best of my knowledge these 3 motors haven't been classified for use in the UK yet, so I've only listed the 6 older motors. The old G33J motors would be an option if any of the UK vendors have some left in stock.

[rocketman]

thanks all. especially robhouse, welcome to trf! in your 3 posts, you've answered 3 different questions of mine brilliantly!

Which parts do I have to buy to have a full rouse tech case? Looking at this
Do I have to buy 1 case and everything else there? Do I need both the forward open and forward plugged closure?
thanks in advance,
Tom

 

[Handeman]

What you've shown with your link are the 29mm High Power motors. These are NOT the same as the Hobby Line cases. The closures are NOT interchangable with the Hobby Line cases.

For the high power cases, you need an Aft Closure, a Forward Open Closure (to use motor delays), the Forward Plugged Closure requires an altimeter or timer to control deployment, and a case. The 29/60 case has 2 F loads available, the 29/100 has 2 G loads, the 29/120 has 2 G loads, the 29/180 has 4 H loads, the 29/240 has 5 H loads, and the 29/360 has 1 H & 1 I load available. I do not know if all of these are available in the UK.

The Hobby Line case here has 9 reloads available, although not all are available in the UK (see robhouse's post).

It would be best to have your Dad or mentor help you.

Said dad told me to ask here!

Said dad told me to ask here!

We can help but need more info first. Are you planning Jr. certification soon? What rockets do you have? You can buy all the HPR cases you want, but can't fly with them until you are certified. With the help of your dad you can fly MPR now. Just need to know what you plan on doing, then we can get you going with correct motor.

I plan on flying a 29mm loc aura with my local club. I want a powerful motor that will send the aura at least 3000ft +. I am going to do a junior lvl.1, but not in the near future.
I have also sent off for an RCA.

Then you want this: https://www.rocketstore.co.uk/shop/prodtype.asp?PT_ID=182&strPageHistory=cat

Third from top - Part no. ROU-T29M That is the HobbyLine motor good selection of reloads, best bet for you location right now. Problem though none in stock!!!!

Thanks for the advice! Estimated arrival time: unknown...trust my luck!

I Simmed the Aura for you on a G64-10 reload, it went to 4,264 feet. The 10second delay is a bit short though. That case is good for E,F,G motors. You want to start out with a smaller motor. That rocket at 4,264 ft. alt. will be hard to recover if at all. Start out with smaller motors, you can always work your way up.

Thanks for simming it for me, it's appreciated I will definitely start smaller!
Thanks again,

If you go with AT try here for the hardware. https://merlinmissiles.com/29_40_120_motor.html

Motor makers cast composite propellant in a standard length (a "grain") that is specific for a particular motor diameter. And there is a linear relationship between the number of these standard grains that are used in a motor and the impulse level, and apparently, often with the motor's class, too. So, for example, a Pro38 reload from CTI that contains one grain of Classic propellant is a G motor, while a Pro38 reload containing 2 grains of the same propellant is an H, etc. The same is true for motors made by Aerotech, Loki, Gorilla, Animal, etc. If you study a set of Aerotech's RMS motor assembly drawings for a given motor diameter (available here; look over, for example, the set of diagrams for 38mm RMS motors), you can see this progression develop as you go from shorter to longer motor cases. So describing motors by the number of grains they contain is a shorthand way of comparing the relative "bigness" or power of them without actually needing to recite the particular N-s of impulse of each one.

EDIT: But to get back to the OP's question, ask 25 rocketeers that question, and you'll get 50 answers! The short answer is: they all are!

Lol, I just realised
Thanks for the helpful advice people, I'm going to choose 29mm rouse tech hobby line.:clap:
