Post T-~Rex 500 e Pro Build Question

Hi all,
I wonder if someone could give me some advice on programming the Speed controller that came with my T-Rex 500 e pro.

It cam with:
●GP900 Head Lock Gyro X1
●RCE-BL70G Brushless ESC X1

I have beed trying to follow the manual re the ESC setup, but as I'm fairly new to doing this (my first electric builkd on my own), I am finding it very confusing.

Thanks in advance

For the ESC, follow the Finless video but be aware that you have to be in a flight mode with a linear throttle curve since you move the thottle stick to high, middle and low positions to make selections when promted by the beeps.

I had my transmitter set on "normal" flight mode (with the throttle curve values from the Finless vieo) and went through the ESC set up. When I would plug the battery back in the beeps from the ESC didn't match anything that I had programed. Based on help from other "Freaks", I switched the transmitter to "Stunt 1" (which has a linear throttle curve) on my DX7, went back through the ESC set up and it saved the setting that I wanted.

Sorry, I ahve not used the Gyro that you mentioned so I can't help there.

Good luck and I'm sure others with way more experience than me will weigh in.
