I Learned About RC Flying From That F 4 Crash

I Learned About RC Flying From That F 4 Crash In this video I will go over what I learned about RC flying from a crash of my foam board F-4 Phantom model airplane. I had designed and built a foam board version of a radio control F-4 model airplane. I took as inspiration, and this is discussed in the video, my success building and flying a foam board model of the F-22 flyer. The F-4 went together well, with the correct center of gravity and sufficient power. However, the model crashed on its first flight after a hand launch. After a review of the crash video, I concluded that the F-4 had its motor mounted at the nose of the airplane, quite a distance from the center of gravity. This motor was heavy enough that at low airspeeds the elevators were just not effective enough at the low airspeed of a hand launch to be effective, thus the F-4 RC model crashed. This was not the case with the F-22, as the motor was mounted very near the center of gravity, thus the large elevons were effective at keeping the nose up at low airspeeds.
