Do not roll operation while turning, it is prone to instability. Although the F - 5 series is unstable as a whole, on the other hand, it can handle high mobility. Since type A was sometimes crashed while in motion, there is no plan to upload at present. B type and C type adopted thrust bias and increased stability during mobility. In addition, because it loaded with flaps, it came to curve more than the F - 8 series. This happened because F - 5C was created as an improvement plan for F - 5A, which was previously made after the F - 8 series was made, and an evolution plan for F - 5B. It is possible to improve turnability by lowering the flap down to the maximum. It is possible to fix it if it is some spin, but please give it up if it becomes drilling condition. This aircraft enters classes where taking off and landing is difficult. Since this aircraft is not stable, we do not recommend long distance AAM use. It seems that we can not respond to ladder turning during operation too much. Since autopilot is near impossible, please maneuver with human power. High mobility at low speed may cause spin in the vertical direction and drilling condition, so please refrain from it.
