1. About this Model

Thank you for purchasing this 1/28th scale JR128-R01 2WD indoor Racer
Ready Set.
JR128-R01 series models are ultra small high performance 2WD indoor racing
cars with a lot of very advanced opportunities for fine tuning and car setup, which
you might find very surprising in a car of this very small size.
9 built-in ball bearings, an adjustable ball differential with 64dp fine pitch and a
1S / 3.7V Lipo battery + charger make you really ready to race out of the box.
The cars are already equipped with a 12mm micro servo for steering, a small
2.4 GHz receiver and an ESC (Electronic Speed Controller) running with
1S / 3.7V Lipo batteries, providing 5.5V current for receiver and steering.
Various other commercially available steering servos, micro receivers and micro
car ESCs for brushed or brushless motors from other brands can be built in and
used in this car. (Attention: Do not use motors with less than 40 turns (40T)
togehter with this ESC, to avoid damage of the ESC!)
Ask your dealer for our brushless motor and ESC - system and for our 2S Lipo batteries,
if you need 8.4V power supply for your preferred electronics.
