Ive ran spektrum dx3r and now the 3r pro for 4 years and have never had any interference issues.And for the past 2 years I've ran straight lipo with savoxs servos on my nitro cars without issues.I've just started running electric cars but so far no issues there either.If your buying the cheapest then you get what you pay for.I have always been a fan of airtronics but really for the features I actually use couldnt see paying the price difference.
