If One is Good, Twenty Four Is Way Better!!
By: leyrerwa
As a teacher of Electronics and Aerospace Technologies at a Technology Center I am always looking for exciting ways to get my students involved in activities that will challenge them but, at the same time provide them with a rewarding sense of accomplishment, increased self esteem and most importantly an opportunity to have some fun while learning.
I have found few project oriented methods that perfectly fit that description better than model rocketry!!
They say that it is always better to buy in bulk! Well speaking from experience, especially through Hobbylinc, that truly is the way to go!
With a class load of 25 to 30 students, it doesn't take long at all to go through many, many rocket engines in a very short time frame. I'm not talking about any waisted engines either. The students simply get so excited about building and flying their rockets, they can't fly them enough.
As an instructor, there is nothing worse, in my opinion, than having a group of students get really excited about a project like model rockets and then be forced to stifle that enthusiasm by having to tell them, sorry, we're out of rocket motors!!
The bottom line is , Bulk Up!! With limited educational funds, buying in bulk is the most cost efficient way to insure you'll have all the materials you'll need for your students, scouts or youth group when their needed and to keep the fun rolling!!
Bulk Educator Engine Packs are available in a wide variety of Impules and delay charges as well as including recovery wadding, igniters and plugs.
Don't be caught short on the flight line!
Clear Skies!
Great Class Ending Project

I teach Physical Science to 8th graders and we always end the year building, decorating and launching these rockets and engines as a celebration of all physical science has helped us achieve. The students love it, other grades come and watch launch day on the football field. Even the elementary students and teachers come over to watch the countdowns and get excited about science. It's a great way to end 8th grade and send them on to the high school.
Great deal!

The B6-4 is a great motor- Decent oomph for it's size, and it'll get a small rocket moving at a very affordable price point. In this bulk pack, it not only decreases the cost per motor, but also includes extra ignitors, and the all-important recovery wadding. This is specially treated paper to prevent your parachute or streamer from being burned. Between all of this, you end up saving quite a bit of money!
Not the best, but...

These aren't the best engines but I don't think that's the point. These engines are for those times when you just want to fire rockets. It's not for performance, it's just for firing rockets. These engines are still good, which is nice, but it's the price of $2 per engine that matters.
Great
B6-4 is one of the best small rocket engines out there. If you want to get into model rocketry pretty heavily and you will be needing lots of engines this is the way to go and buy a big box right away.
Great deal

The best price, especially when you factor in shipping, of estes engines I could find. I bought these as a nice medium thrust engine for a bulk pack of rockets I got for a scout activity.
Perfect, as advertised. Great performance

Spectacular launch, great reliability. Shot all 25 in one sitting. Scouts were so happy with the height and the show. Each engine performed well.
great kit
bought this for a boy scout group. and the scout leader was very happy cuz it was a better deal then what he was getting just love

This is a great choice for most 3 ounce or lighter model rockets. Best first flight engine for any lightweight fleet.
almost max altitude

This works well on semi windy days. This makes it so it doesn't go to high and get caught in a cross wind.
enough to start with
ordered these along with journey launch set so we could get right to launchin..........
B6-4 Engines

Perform well with no apparent issues. (Obviously) more thrust that the A engines.
