Impressive

One of these threw a 3D printed rocket I designed to about 1400 ft. It was still headed upwards when the ejection charge fired! Came back in one piece, too. I have never flown anything larger than a D engine prior to this, but I will absolutely be buying more of these.

Double check the engine number!

Bought the wrong engines and you can’t return them by mail. Double check which ones you need!

Yeah they’re back!

Just in time for my launch at the Santa Fe dam on Dec 7!
