Increase in motor size with a propeller change, reducing drag on the plane
Speed and flaps.
It's a toy that requires electricity.
Flaps would increase drag increasing your speed will increase it even more
Airflow ans lift over the airframe is affected by the airplane's speed.
An airplane's fuselage affects it flight by a lot. It can change its speed, maneuverability, angle of attack, and even its necessary-for-flight wing size.
One can make a toy airplane by purchasing or cutting out wood wings and a body. Then cut a slit in the two sides of the body and insert the wings. To make a paper airplane, simply fold the airplane in half, then fold the sides down at an angle to create the wings.

The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
He had a pain in the neck.
Yes, it is a toy machine.
No. 'Airspeed' is the airplane's speed relative to the air. 'Headwind' and 'tailwind' ... in fact, 'wind' in any direction ... is the speed of the air relative to the ground, which the airplane doesn't feel. So 'wind' affects only the craft's groundspeed, not its airspeed.
Mach 1 is the speed at which you break the sound barrier. The speed of sound, or Mach 1, at sea level and under "standard condition" is:1,116.4 ft/s340.3 m/s761.2 mph1,225.1 km/hRead more: How_fast_do_you_have_to_be_moving_to_break_the_sound_barrier
