Otto,

I am not wanting to throw a spanner in the works here but im not sure that your use of the victors LED will be sufficient.

The victor that I use flashes on and off an orange signal if no proper signal is received from the receiver. This would not do for a power indicator as a power indicator cannot flash.

It shouldnt be too hard to quickly wire in an LED to fix the problem (I have done it the night before a competition a few times!).

You are best contacting the event organisers directly with your concerns as they will be able to give you a yes or no.
