Are we sure that it is just the frame rate of the camera? Just seems a bit fishy.

Throttle on helicopters is linked to the collective pitch control (the angle of attack of the rotor blades). Engine speed does change throughout the flight envelope, but the rotor speed is kept in a fairly narrow range. The main reason for this is that it's much quicker to change the pitch of the blades to affect lift, than it is to overcome the momentum of the spinning blades.
