The IR sensor in a Heng Long is focused at detecting a different Frequency then the DBC or Tamiya. IF you buy one of Davids DBU kits you have four IR sensors that can be used in this conversion. The HBU(Heng Long battle unit) has a mirror assembly like Tamiya and only needs one IR sensor per unit. You take out the Heng Long Sensor and install one of David's in it's place. The pin out is different though so you have to make sure you get the pins on the sensor where they need to go. Using Davids DBU instructions you can figure out which pin is which.
