I do have mussle spassans tingeling in my arms.. I can't sleep at night either.. As far as the check out on the radio.. I checked it right out of here.. I then bought the first 7c 2.4. I bought it new from tower then had to send it back due to a bubble in the lcd.. But I do have 4 other 72 mhz systems all Futaba. ch 48 and 55. It's crazy I set up the plane on the 72 band walk around and glitch glitch bind. It acts as there is someone else on the same channel as me.. But I do have a scanner and on any given day no one else is on. Heck no one is on where I live.. But when the plane does this I hand the tx over to my girl and she can walk out of sight with no trouble at all. Then she will walk back I walk in between her and the plane full down and or full left or right aileron. I mean a full lock. It has striped gears because of this.. I take you have heard of this ??
