I asked the same range question down a few posts below, if you haven't checked this post above out, try it, there's some mod ideas, one includes a 27mhz getting like a 30ft+ range or so, those might help you. you can boost the range of the 27mhz, its not impossible, just probably harder than if you had a 49. hell, i'd give you my silver porsche shell if i didn't mod the hell out of it =p
if the list doesnt work just look for the post on the forum, it's pretty helpful
