This plane design comes from Stratolaunch- Systems and its partners
Paul G. Allen had an idea to fund a project for the worlds largest plane
The wing span is going to be 117 meters and weigh 590 metric tons and it will carry a rocket with a payload of 6 metric tons
My plane is only a rough estimate of the real plane because i could only find a few stats and mainly based it off pictures
The one I built is a little bit smaller with a wing span of 112 meters and only weighing 360 metric tons with 189 parts
This plane does need the majority of the runway to take off and you have to go slightly to the left side of the runway so the wingtip doesn't hit the fuel tanks next to the SPH and climbs the best at 7 or so degrees it does how ever like to float in different directions so you will have to manually control it most of the way up to the rockets launch altitude of 9,110 meters
You can change the payload of the rocket to something else but right now it is a fuel tank to simulate the payload of 6 metric tons
The wings do bow like a lot but I haven't had them brake on me yet
The aircraft it stabile in FAR with and with out the rocket
When you launch the rocket you do have to use full throttle and the lift buster I put on the side to keep the nose up until mach one but after that you want to throttle down to around 50% so you don't go through your fuel in 15 seconds
