I reentered the hobby last year after a 15 year break so everything is new (mucho cars have I) 2.4 radiios, brushless and lipos are the bomb. The car I bought was complete other than an rx and has only a few runs on it.
So I had a little time and did some component swapping.
The LRP got signal from another rx, I didn't attempt to program it however. Conversely when I plugged a working esc into the suspect new out of the bag rx it did not get a signal so I think the rx is bad right out of the bag. More testing when I have time to verify. In the meantime I will use a known rx and install it and setup the lrp with it. The TX has room for 9 more cars, guess I need 9 more recievers.
thanks for the tip
