This turned into an expensive weekend. It started with, what would be, the 5th flight of my Magister. After about 3 minutes of performing simple aerobatics, I decided to do "touch and go's", unfortunately as I banked the airplane to begin an approach run, I lost all control of the plane (I don't know if it was interference or what) and ended up planting the plane from about 75 feet in the air, directly on it's nose, which destroyed the gear box, motor, the wing mount, and the aileron servo. As bad as that sounds, it gets worse. I decided to fly my stryker and after a couple of close calls, (due to, I assuming interference again) I decided to pack it up for the day. Which brings us to today. My first flight for today went well, I flew two batteries out of the stryker with no problems. Then it happened.....battery 3 in the stryker, during level flight, at 3/4 throttle the plane rolled left and slammed into the ground. Before it hit, I was trying to counter it, but the plane did not respond. Luckily the plane was unhurt (amazing how tough that plane is.) I decided to let the stryker rest and fly the T-28 (maybe I'm just being stupid at this point), after turning on the TX and plugging in the battery, I started to taxi the plane, getting ready for take-off, just as I throttled up, the motor stopped immediately, the prop was trying to spin backwards and frontwards fighting itself, I went over to pick up the plane and unplug the battery, after checking all of the connections, I tried plugging the battery back in and the arming tones were so quiet you could barely hear them. When I tried to give it throttle nothing happened, all other control surfaces were responding normally. So I decided to put the T-28 away and fly the only plane I had left, the stryker, only to have the speed controller to go up in smoke, as soon as I plugged the battery in. Is this normal????? The temperature at the time was about 90 degrees out, the stryker had been sitting for about 45 minutes since it's last flight. I've flown at the same spot for the last 2 months with no problems. Any ideas of what could've caused all of this?????????

On a side note, after I got home, I swapped the speed controller from the T-28 to the stryker and the stryker works fine now. The T-28 on the other hand, with exception of control surfaces, doesn't work at all. Could the brushless motor in the T-28 have fried, seeing how the speed controller works fine in the stryker??

As for the Magister, I'll save that for another thread.
