I was just looking at the EI MOD website and I see they have built an IR battle system to go with their extensive electronics upgrades for Heng Long.

Seems as if they have improved on the game a little. Apparently four sensors means they have programmed in different hit damage depending on where the tank gets hit. You can lose left ot right control of tracks or turret rotation. System also has provision for the holy grail shot that can take a tank out in one hit. Interesting concepts as they try to take IR battling to a new level.

69 euroes is not bad for the system and "mushroom" Of course you have to invest in the other EI MOD electronics as this works as an add on board.

The frequency is the same as Tamiya so they are compatitble in the fact each system can register hits.
