I "think" this is the suggested fix:

Hello,
How are things going for you at the moment?
Have you received the introduction we sent you last week regarding the
small drone?
To ensure that you receive this email, I'm sending it to you again
through this channel.
The drone has a 30-minute flight time and can record footage at a
25-frame-per-second frame rate.
Dimensions: 45x40x12cm (before folding) Dimensions: 21x11x9cm (after
folding)
Dual-mode The positioning system provides GPS positioning. 1806 is the
model number for a brushless motor.
3000m (about) remote control distance
The remote control's height is roughly 120 meters.
For shooting with gesture recognition, a distance of 1-3 meters is
required. Resolution of aerial image: 4096 * 3072 (APP)
2048 * 1080 video resolution (APP)
Frame rate of transmission: 25 frames per second
The angle of the ESC camera is 110 degrees.
With the push of a button, you may direct the aircraft to take off,
land, and even return to its original spot.
When the drone is summoned, it will return to the location from which
it took off.
Fixed-point surround: you can now make stunning films with this
professional drone without any additional effort on your part.
The following are the pricing details for various quantities:
1 to 10 units: 235.90 each
11-20 units: 225.90 each
21-50 units: 195.90 each
Would you be interested in purchasing one or both of these?
Send us the location of your delivery, and we'll contact the logistics
department on your behalf to make the required arrangement.

Optical flow is formed by combining a fixed point inside the system
with a GPS position retrieved from outside the system.
As soon as you step through your front door, the electricity is either
turned off fully or you receive a notification stating that the power
has been turned off.
A virtual reality mode, as well as the option to switch between several
lenses, a video/picture panorama, and a video/picture panorama, are all
included with this camera
There are also modes including MV (which returns to the home screen
with a single press), headless, photo/video gestures, and front lens
adjustment. Each of these modes has its own set of features.
The GPS and air pressure combination employed in the system for flying
at a fixed altitude is essentially a hybrid.
Wind resistance is rated at an 8 and is measured in meters per second.
Thanks,
Leo Bryan
