Plane lost control today. No response from radio, plane nose dived 1000 ft into the ground. Pieces everywhere. Flying a T28 Trojan that has been awesome. I'm using a DX5 radio from the Apprentice kit. Has worked fine several times. After the crash, I tried the controls and they all worked. Albeit, in pieces. What happened? I'd like to upgrade to the p51 by eflite, but should figure out why this kind of thing would happen first. Thanks.
