Crazy
This massive rocket said it would go up to 800ft on a E engine. I launched this rocket my first time on a d12-3 engine. It blasted off the pad to at least 1300 ft I figured it would only go about 500 ft high with that small of an engine. But I was wrong something with this rocket is rated wrong so beware make sure you have a very large launch area mine floated so far that it landed in a cornfield where I could not find it and it got rained on and it was ruined. But it is a very great rocketmake sure you have a long enough delay.
