The gear ratio should be specified in the instruction manual for your helicopter. Especially with electric models it will vary depending on the motor pinion used. For helicopters with a single-stage gear drive the reduction can be calculated by dividing the number of pinion teeth from the main gear tooth count.
Example: Shape S8 - Main gear tooth count 130 teeth / 15 tooth pinion. Gear ratio apprx. 8.65:1. F - Status-LED purple flashing, G - Status-LED red, H - Status-LED purple.
For SAB Goblin helicopters you can calculate using a 165 tooth maingear. I.e. 18T pinion will result in 165/18 apprx. 9.15:1. F - Status-LED purple, G - Status-LED flash. purple, H - Status-LED red.
