Yes but with the IBU, the emitter is virtually identical to the TBU's one, so how does one tell if they are using a legal emitter for teh competition? Things like that are hard to regulate. Esp for an official tamiya competition, you will think that one needsto use only tamiya battle units?

The whole point I was trying to put across is that why put something that has an advantage in your tank in the 1st place when your man intention was fun. Its not like the said user did not have an original tamiya emitter, its just that he does not want to give up his advantage he had on others.

Anyway, I am not saying the the IBU is not good, coz it would seem that certain ppl are defending it esp when business is concerned. I am just stating my 1st hand experience fighting with such a system. When your 45 deg defense is 1 metre less than your opponent, I wonder what kind of tactics you can come up with when he plays the tango with you.
