The Goddard, the very first rocket ever made with liquidized fuel, was built in 1926 on March 16th. The rocket was recorded to reach speeds of 60mph reaching an altitude of 41ft. The scientist who made this contraption was, Robert H. Goddard. It was believed that this rocket flown in Aburn, Massachusetts was using a early form of Monoropelent and small amounts hydrogen, although no one is really sure. Not much information was left by this scientist other than a photo and notes of his invention. The rocket itself is connected with poles carying two stages at the top and bottom. These stages can be fired at the same time and lift the rocket for a few seconds above the ground. (However, my current model does not fly for a few seconds, it is more around a minute and it reaches higher altitudes.). Note: When flying make sure to use Monoropelent controls and throttle to fly.
It was gasoline under pressure and liquid oxygen the ‘stage’ on the bottom was a heat source to ‘pre-heat’ the lox and force it up the tubes you mentioned. How come you didn’t go all out and make the frame so ppl would recognize it and give you some upvotes. Also if you keep it to the spec’s the replica crowd will give you more votes than a second stage that makes it fly far or even straight up, as I recall the story it flew 41 ft up and a distance of 189’ in distance. A Wright flyer that handles like a p51 isn’t going to do as well as one with realistic historical significance, which this certainly was. I will upvote you once I post my crafts.
