Today I tried to have an IR battle with a friend.
We both have taigen tanks with the v2 control board. My tank is 1 year old his is brand new.
It seems his tank is unable to hit mine. He fires but tank does not react

We swapped the IR receivers - same problem.
We checked the IR Led on his tank - this one is fine.
Both tanks react to a simulated hit from my universal ir remote control.
So it is pretty sure that my tank is not the problem.
Any suggestions what I could check next?
