The BD10 Setapp is for all Yokomo racers out there. Have a quick look at the manual, check the team drivers setups or create your own setup sheet and save it inside the app. Calculate the gear ratio of the BD8/BD9/BD10 or any other touring car and set up the toe-in and toe-out of your BD8/BD9/BD10. On top, the BD10 Setapp features a stopwatch for timing your practice laps or full runs.
