I'm new to rocketry and trying to make heads and tails of Aerotech's motor branding. Hope someone can clarify these product lines for me. Their lineup includes Econojet, Economax, Enerjet, Aerotech, Q-jet, and maybe other I don't even know. Their product catalog seems very outdated and only mentions Econojet but doesn't provide much as to the difference in performance. It seems these all share the same propellent type so where are the differences? The catalog also mentions Kosdon(KBA) and KBA "Animal-Safe" but doesn't provide any information on how these differ or what Animal-Safe refers to. Seems Aerotech could do a much better job of outlining their products and updating their materials/website.
What gives? Thanks
The reason you are confused is that Aerotech is terrible at branding. I love the motors, but the branding is extremely inconsistent and confusing, which goes entirely against the basic concept of what a brand is. Brands are supposed to clarify, not confuse. It seems to me that Aerotech’s sub-brands Econojet, Economax, Enerjet, and the E20 2-pack motors without a sub-brand label all have blurry lines between them, so there is little brand distinction, and when you do figure out a distinction, there is often an exception to the rule. So basically, they don’t make sense.
What is similar between all of those sub-brands I listed is that they are all relatively affordable for single-use motors, and they all come in plastic clamshell 2-packs, and they all come in a range of fixe, non-adjustable delays. So that’s an example of a lack of distinction between the brands — what’s the difference between EconoJet and EconoMax?
One other similarity that helps put the “Econo” in the name is that they all ship without a hazmat fee, EXCEPT for the G74, which exceeds the propellant weight limit. So that’s an example of an exception to a rule that helped to define the brand.
In general, I think you can conceptually lump all the Econojet, Economax, Enerjet, and the E20 2-pack motors together as affordable midpower motors that ship without hazmat (except for one). If I were Aerotech, I would rebrand these all as a single brand and probably ditch the G74 or exclude it from the brand.
Branding issues aside, I like these motors and use a lot of them at midpower (non-high power) launches.
The E20 motors make a nice upgrade for Estes rockets designed to fly on 24mm Estes E12 or E9 motors. The F44 will also fit those rockets, but has a LOT more thrust. I sometimes use that one in a 29mm motor mount with an adapter.
EconoJet motors F20, F23, F27, and F42 are all nice for midpower rockets with 29mm motor tubes and body tubes in the 2” to 3” diameter. The F20 is one of my favorite motors.
The EconoMax F67 is a nice motor for heavier midpower rockets that need more thrust. And the G74 is a good motor, especially for larger rockets you want to keep lower than a full-sized G would allow, but I only buy that one if I’m purchasing other hazmat items.
