alright i have a spectrum system...tried putting a known good reciever in my X5 truggy, when it is installed i get glitching like crazy on my steering. tried other servo's and still glitches....even tried another known good reciever from another car still glitches..... now when i put the recievers and servo's in any of my other cars no glitches at all....what could this be.... i ended up resorting to using my old school crystal fm transmitter and reciever and it works fine in the X5....some crazy stuff goin on here
