Hello I race 10th scale pro stock truck and need to upgrade my radio system and was wondering if anyone could tell me the differences between the Airtronics m11 and m11x.

better reponse time
lighter and rx are smaller too
the rx can support hv servo

me a have 3pm 2,ghz before that and when a have this radio this was a major upgrade!!

Also, M11x has a built in module which is better than having the 2.4ghz module antenna sticking out precariously at the back of the transmitter for the M11 (if you choose to swap the module to a 2.4ghz)
