my skysport 6a seems to have limited range.. i get around 85' with antenna fully colapsed , is this ok?? ( i get 3 times this on my other radios ) radio was just sent in for checkover & tune.. its in a 1/3 pitts with g38 , but i get the same range motor running or not.. i was told 85' was ok for this radio , is this accurate ?? any advice appreciated !! thanks rob m
