I got my home built IR battle system installed into a T-34 and a Tiger. A lot of trial and error but I have something that works pretty good now. The Tiger is fully loaded with EI mod electronics, and VS tank airsoft cannon. Ouch, this one you have to be careful with.!!

The T-34 continues to get pieces added, and this one is basically a Heng Long T-34. No airsoft gun, just the IR battle system.

The saucer thing is an inverted parabolic mirror that redirects IR hits down to an upward facing IR reciever.
