This is a 400% boeing 747. It flies almost the same as the original but the top speed is around 280 in level flight, 400+ in a dive. It takes off with half flaps around 100mph and lands around 95. The reverse thrusters are very helpful in slowing it down after landing. Also be careful landing because the landing gear is not very strong. It weighs about 1600lbs and has a 16.4 ft wingspan.Thanks and nice job for the original design Seraphim. Please rate.
