We could suggest the manufacturer have a LED intensity setting for class of tank, i.e. switching to heavy would increase range OR register 2 hits on one shot for instance.
This would alleviate any tampering of the detector and put the setting where it should be - on the circuit board.
Yes this is what I would suggest. I am hearing everyone thinks the range of the current emitter is enough for long range. That makes this very simple. A small circuit board could be inserted between the IR LED output of the MFU and the LED. The power delivered to the LED would be set by adjusting jumpers that route the MFU output through different resisters on its way to the IR LED. This resistors would drop the current feed to the LED to produce ranges of 10 and 20 meters.
Simple and effective, with no change to the current Tamiya or DBC. Just a small plug in board.
