Flying yesterday and the Apprentice seemed to be nose diving almost thought I had lost total power of it went on a preety serious dive had no trim left got it down safe... Tried to manually trim from servo arm than took off little bit better same thing was happening trim was all out of wack . I think the battery was not seated 100% tight. Anyways plane got a little far from me got a little nervous and you know what happens from there......tree magnet. Plane is approximately 40-50 ft in tree in a persons back yard who is actually nice lol. Did some reading and it seems the tennis ball with fishing line is the best solution any ideas would be highly appreciated.... Thanks in advance
