Hi it seemes to be hard to tune,have to adjust the hs needle 1/2 turn every day? (my os .18 is like "set it and forget it") also the primer on the tank,stoped functioning properly after about 5 tanks.at my LHS I saw one with the primer removed,and the hole epoxied shut.I wonder if its leeking air there,and this is why it wont stay tuned? I live in illinois,not to drastic of weather change this time of year.any problems like this?
PS:this fancy radio says I can run 6 cars,do I have to buy 5 more of those $80 recivers?
