A DBC3 in an HL Airsoft tank will allow you to have a full functioning airsoft HL tank and you can have a completely Tamiya compliant IR system,

Just a recap on the DBC3 features, as it appears people are not aware of all it does.

Completely Tamiya compliant IR, with weight classes complete with the interface with the drive motors to slow down the tank when it has been hit
Blocks the Heng Long recoil jerk
Removes the superspin
Adds Momentum
LED Flash
Interfaces with a standard RC receiver

If and when you want to add Benedini sound that option is available to you.

Plug and play for $100


Cheers
