2. Esk8 mode:
ZERO position: 1.5ms;
Throttle button: 1.5-2ms, max throttle is 2ms;
Brake button: 1.5-1ms, max brake is 1ms.

MTSKR1905WF Tips of Usage:

1. Wash the remote in freshwater after using in salt water.
2. The remote PCB is sealed by waterproof nano-coating and double protected by glue. The remote screen is sealed by waterproof nano-coating, not glue. When use it in water, water will get in between the outside and inside screens. It won't influence using. When you don't use it, please put it in dry place and it will dry slowly.
3. When charge the remote, please keep remote dry.
4. Receiver is not waterproof. Please put receiver in dry place.
5. Because each customer using situation is different, some customers may need replace the antenna with longer one . If you mount the reciever deep in your board, recommend to change to a long 2.4ghz antenna and lead the antena near to your top cover of your board for better signal.
6. When soldering, please pay attention that the two pins do not touch each other, otherwise it is easy to burn the receiver.
7. The extended antenna 1m and 3m PCBs are not waterproof.

MTSKR1905WF Note:

Now on sale is the MTSKR1905 remote control upgrade
Advantages of upgrade:
1:The signal of the upgraded version will be more stable.
2:The upgraded version uses magnetic filling glue, which can prevent rust and corrosion.
