Quick questions for the Airtronics crowd. Im getting back into RC and a lot has changed. I am looking to purchase the M11 or M11X. These requests are trivial so bear with me. I noticed on someones car that they had a very short receiver antennae that was kept under the body of the car and supposedly worked as good as the long antennaes. It was an Airtronics. Is this type of receiver available for either the M11 or the M11x? Next, I really dont care how fast my radio and servo set up is because my old M8 was plenty fast enough for my horrible drving abilities. Do I still need a digital servo? How can I use my old servos? I like the 2.4ghz synthesize system but I would like it with a short rubber antennae out the top rather than the side. is this only available on the M11X. Any help is appreciated. Thank you, G
