When I built my 1964 1/12th scale RC Mack Tractor (YT channel @cranemodelbuild, most recent video) I had a Spektrum DX8 Gen2 Tx and a Spektrum AR620 Rx available, so that is what I used. Now I am looking to switch the model’s radio system over to a 3 channel surface Tx/Rx system. I am looking at purchasing a basic low cost Spektrum Smart 3-Channel Tx with a SR315 Rx for about $100. Let me know if there is a better Tx/Rx set up I should be considering in that price range. Thanks!
