I have yet to use these engines

I have yet to use these engines, but I can say they came well packaged and well protected in shipment. I haven't even started building the rocket that I purchased thes engines for, and doubt I will build it until sometime next summer as we will be wintering in Florida in our motorhome until next spring.

Reliable engines

Even though I made a mistake in ordering these engines, I know they will work in what ever new model I make with the correct size tube.
