Sorry to hear about that!

It could have been worse! I know of one pilot who had his model so perfectly trimmed that he did not use aileron on takeoff. When he did, 20 meters up, it rolled over and crashed. Later, the accident investigation found he had plugged  the Y harness for the dual aileron servo backwards, and did not do any checks after.

Remember to check the model over before, AND after the wings  go on!
