Question

Which things should be kept in mind with regard to flying of aero models? Mention any two.

Hint:

Think about the place of flying and the set-up of wing and tail.

Answer 1

Step 1: Understand the question:
We must write any two things to keep in mind while flying aero models. Each correct point earns 1 mark.

Step 2: Point 1: choose the place:
A large open air field must be chosen for flying the aero model. A wide space keeps the model, the flyer and the onlookers safe.

Step 3: Point 2: check the alignment:
First check the model for correct alignment. The wing and tail must be checked from the front and rear for setting, and they must not be warped or out of plane. A bent surface makes the model fly badly.

Final Answer:
Fly aero models on a large air field, and check the alignment of wing and tail before flight. \[\boxed{\text{Large air field; check alignment of wing and tail}}\]
