Full review video by Albert Kim The video gives you a perfect answer of how the Beta75 Pro 2 performs.

Daniel Sugano 's flight footage of Beta75 Pro 2 prototype.

X series, like Beta65X or Beta75X, represent the highest performance of 2S whoop drones. With long range rx, powerful ESC and motors, pilots would fly the X drone like a smaller mini drones; Pro series, like Beta65 Pro 2 and Beta75 Pro 2, have a higher integrated AIO FC and lighter weight, pilots fly it like a faster Tiny Whoop drone.This is the biggest difference of the X series and Pro series drones. You could have a noticeable different experience in control.

Here is a specification comparison of the 75mm brushless drones, Beta75X and Beta75 Pro 2.

The smaller brother Beta65 Pro 2 is available too. Get a Beta65 Pro 2 here.

BULLET POINT

FAQ

1. Does this drone have current sensor?

This drone does NOT have a real current sensor. We use the virtual current meter in Betaflight. When properly calibrated, it can be accurate enough to be useful. Here is the pre-calibrated value out of the box.

set current_meter = VIRTUAL
set ibatv_scale = 90
set ibatv_offset = 29

2. Binding procedure of F4 2S AIO (SPI Frsky RX) is given in our support page.

3. Cli Dump for different versions of the 2S Whoop are provided in our support page.

4. The camera angle is 35 degree by default but a spare camera mount with 25 degree is also attached to the drone.

5. If you are using EU-LBT firmware radio controller, you might find that you can't bind successfully to this SPI Frsky receiver. Here are the solutions we provide for you.
