Some time ago I purchased a Spektrum dx6i dsm2.Along with this Tx I purchased 9 orange rx plus satellite rx this combination worked ok.Later I purchased a dx6i dsmx Tx which also worked ok with the dsm2 receivers.The dsm2 TX became faulty and sort to get another dsmx TX.I was advised by suppliers that the dsmx could not be used with dsm2 receivers but the manual clearly states that the dsmx TX can be used with all dsm2 receivers do I need to ditch all my receivers
