Few questions about the Short Course Nationals

[berry50]

I've just built up an SC10FT and am going to enter the next round at A1, but i've got a couple of questions if someone can spare the time.

1) I haven't got a transponder. Are they provided?
2) How are they mounted? I used to race 1/10th 2wd about 10 years ago and they were mounted in the wing. Not sure how to mount them in an SC truck.

Think that's it for now. Just hope i don't do too bad
