PROBLEM TO BE SOLVED: To easily hold the flying posture of a radio control type model plane to the set posture including the torque control and hovering. SOLUTION: This device comprises a combination of sensor units in the X and Y axis direction 11, 12 to detect the differences of brightness between the right and the left of a plane body as well as between the upper and the lower V1, V2 and first and second signal processing units 21, 22. The units 21, 22 perform switching between a hold condition to hold the differences of brightness V1, V2 from the units 11, 12 to standard values Vo1, Vo2 and an operation condition to compensate the differences V1, V2 based on final compensation valuesΔV1,ΔV2 at the hold condition, and the flying posture of plane body can be held constant via a posture control means 40.
