Well one bad day, something happened, my instructor take off the plane and he scream "I have no control" and the plane crash, not much damage, it's ready for tomorrow but my instructor felt very bad, I told him to no worry about it, **** happens, and crashes are part of the hobby, then a tease him telling him that today I learned 2 lessons:
1.- How to repair my plane, and
2.- Give the buddy box to the instructor

ja, ja, ja; we have another flying field like 2 miles away, and we have a frequency deal with those guys, my best guest is that someone at that field used the wrong radio, because no one else at the field use my channel, and when we check the radio after the crash it was and is working perfectly.

Well lets hope tomorrow is going to be a better day.
