*for flysky nb4
The first micro surface rx with an antenna-less version that integrates a transponder with editable personal ID number.
After using this receiver, users no longer need to install traditional bulky transponders on 1/28~1/24 RC cars.
Users can also modify the transponder's personal ID number easily and unlimited times.
When the transponder is not in use, the user can turn off the transponder on the receiver through the GUI (TP_LED is off )
 
No need to add a transponder and make your car a mess or heavy, this micro receiver has the transponder built into it!
Works with EASYLAP.
