Nitro Receiver Question
 

Yo guys -
I just got a new to me HPI nitro truggy.

I have Spektrum D4 transmitter, and my other cars/trucks have been switched to a Spektrum rx.

Question is - will the standard Spektrum rx work?

If not, what do I need to be looking for?

The tx and rx are fine the way they are, but I have the DX4 for a reason (mostly cause I don't want to have to deal with more than 1 tx.)

Thanks
