Hey Jeyjp,
if you can please post pictures of your modification. I've been seriously considering getting the spectrum but a couple of guys had wierd issues on the track this weekend with 'em. I say it was wierd because before their cars worked fine bout 1 out of ever 5 races they complained about loosing signal. One racer said as a turn marshal got btwn him and his car the car went dead.!!!!!!!!!! So i'm not sure. But on the other hand alot of non specturn drivers had problems as well on the back straight away.
What is the likeliness of the spectrums causing interfarence with the non spectruls an visa versa? Its seems to me that the more spectrums we get on our track the mroe problems we seem to have, but that could just be my imagination.
