I originally planned to have another video along side this one with some mid powered rocket staging but unfortunately for the rocket sled we just had a heat wave that melted all of the snow. To bad I found out this late in the season that E9 is the perfect amount of thrust and burn for the rocket sled. I plan on still using the rocket sled in the summer and seeing how it can go over both sand and adding a skid plate to the bottom and seeing how for I can hydroplane it. stay tuned. thank for everyone that enjoyed watching the evolution of the rocket sled this winter. Sorry for the short video as I said it was intended to have more launches in the footage.
