Etronix Pulse Transmitter issue

[gainsy]

Hi
Been using my Etronix pulse transmitter with no issue's for the last month, that was until my son drove his monster truck over it & destroyed the throttle stick!!
It's completely destroyed
Tried emailing the company to see if i could get the parts to fix it but have heard nish back from them
If i was to buy another set would i be able to bind the new tranny to the old receiver as well as the new receiver? so i could use 2 cars but 1 tranny
Cheers
