I have used this reload many times without any problems. I have flown in My G Force at least10 times, also in other mid power rockets as well. It is always a crowd pleaser with thick white smoke and a loud ROAR!!!! I keep 5-10 of them on hand at every launch. It doesn't take long to load, actually takes longer to clean between uses than it takes to put together. I have 4 of the 29mm 120 cases and I build at home the night before the launch, that way I can fly four times before having to reload. Great size and Quality product

this motor kit could over power your RMS case blowing off the aft closure and nosile and go right threw your rocket CATO cheap case has only 2threads on it .you might think you did somthing wrong probl not

This Aerotech propellent reload provides quite a lot of fun for the money. When launched, it provides a bright white flame, a thick columb of white smoke, and a loud roar as it flies. I fly this reload in my Aerotech Mirage and it's always a blast. If you've never used a reloadable motor from Aerotech it's definately worth it. They can be a little time consuming to reload the propellent into the hardware, but you get good at it after doing it a few times and can get to your next flight in just a couple of minutes.
