I had to rewire all 3 of my of Clarks like I posted above to get them to work. After that they would take hits from all over, even in seperate rooms, they didnt seem to be accurate at all, the tanks didnt even need to be pointed at each other to take hits. I then installed Tamiya Battle Units with the Tamiya IR emitter. Now they work well and even work great with my BARC4/TBS mini in HL Tiger I. If you dont plan to battle other IR tanks, or not to worried about accuracy, the Taigen Apple will work fine, just rewire as posted above.
