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 ( to be clear this is not just for the DBC3 chip, this is for a complete plug and play DBC3.)

You will have to use a hobby receiver and radio. THe DBC3 does away with the Heng Long radio

If you want Benedini sound you then have to purchase the Benedini TBS for $139. This is a programmable sound card that allows you program what ever sound you want in the tank. So you don't need a sound specific sound card for each tank you own. If you put the sound card in a Sherman , you download a Shermans sound set. IF you move the sound card over to a Panther, then you just download a Panther sound set into it. The system is very versatile. You could have the DBC3 in every tank, and then just have one Benedini card to move around. It is plug and play and takes minutes to swap over. Or you could build a DBC/Benedini/ receiver package that you move between tanks. I have done up a video showing how simple it is to move a prebuilt package between HL tanks. It is available on my web page on the demo video page.
