i am not quite sure what all this dumb thumbs fault is about. personally, out of 4 years and 4 crashes, only one has been my fault. my 1st crash was at the infamous basin where i got a radio hit, (everything worked fine afterward. crystal was in when i found the wreckage and battery was charged and plugged in) the 2nd time was one of the best recoveries i could do with about 0 airspeed and 5 feet off the ground with a deadstick, (not good) the 3rd time was when the wing peeled back on my cap 232 (just a simple spin folks) and the 4th was a mid-air, just a couple of weeks ago.
