mostly becuz i still see a fair portion of LS user continue to have issues with spectrums. even the almight Rs. imo, they are a great radio for anything NOT GAS. i wonder how the Air guys that run gassers are liking their Spekys. but i know alot of the gasser guys are still hit and miss with them.
maybe i shouldnt say they are junk, but rather worthless for a gasser.
as far as 2.4 goes, you can bascially run up to 80 Like Units at the same time in the same area. the 81st guy will have to wait for someone to shut off to get an open channel... pretty cool poop really, when it wont even connect to its own bound rx if there isnt an open channel. No worries ever of turning your radio on, or haveing someone else turn on theirs, and taking a rc out of commision.!
