Plane Big Stik 60.... 2 pervious flights, same crystals.... Yesterday after pre-flight cheked O.K. I taxied onto the runway and gave her full power for take-off "Nothing" the elevator would not lift her off, tried to shut-down the power and again "Nothing" and into the wire fence around our field. 80% destroyed..... Later my buddy, 30+ year flyer, checked the plane out. We found that with my original crystals nothing would work, we then changed to another frequency "Crystals" in the radio and receiver and the servos, etc, would work. Back to my original crystals and again "Nothing".

We believe that the receiver crystal failed!

Any idea's, suggestions, or does anyone think our "Autopsy" was correct??

Thanks [&o]
