"You need this system!!"
rbeard2 (Dayton, OH)
For anyone considering the move to mid-power, you need one of these versatile reload casings from Aerotech! E16, F22, G79 and many other propellant kits and thrust curves are available for this one case! The instructions are very well illustrated and easy to follow and once you've put or three of the propellant kits together it becomes a piece of cake! I use mine at least once at every launch and if you have a flat surface (my car truck) and a pack of Clorox wipes, you can clean and reload your case between launches in about 5 minutes! Good stuff!

"A must have case"
jboldig (Stafford VA)
I bought my first Hobbyline RMS 29/40-120 case in 2003 and have been flying it ever since. A conservative estimate is 120 flights so far and I just ordered another dozen reloads for it. The Yellow silk screen label might be a little worse for wear, but the case itself is just as good as the day I got it. Considering the low cost of the reloads, you can't fly any cheaper than this case. I haven't met any adult rocket hobbyists that don't own at least one of these cases and many of them have two or more.

 
"Your gateway to Mid-Power"
skydog (skydog538@gmail.com)
These casings are close to the most fun you can have without an HPR certification. I've never had any kind of problem with these cases, but I AM very meticulous with my assembly and cleanliness. If the wind is blowing hard enough to make assembly difficult, It's probably too windy to fly anyway! Yes, the CTI reload system is easier and quicker, but for me, it's not JUST about saving money... I actually enjoy spending 10 minutes building the motor, because I feel more involved in the final outcome. It is of the utmost importance that the instructions be read and followed exactly. Even though I've assembled dozens of motors, I still keep the instruction sheet open in front of me. There is enough difference between different reloads that it really pays to keep the instructions! All it takes is a pinched O-Ring or loose threading or part misplaced or omitted to destroy your beautiful flying machine. This makes me feel more like I'm actually doing Rocket Science!

 
"Great, but hard to clean"
navypilot2007
I've used this case for five launches now, and every time I have the most difficulty unthreading the forward closure. Even when you assemble the motor properly with lubrication and all, grit and grime gets in the threads somehow. The threads are also very difficult to clean. I don't have similar problems with 38, 54, or 75mm motors. Otherwise, this is a fantastic part and is definitely worth the investment for saving over disposable motors.
