HI all. I'm happy to have my new wing installed in my SlowPoke Sport 40. It went down hard in the fall. After having everything reassembled the other night i used my field charger to charge for speed. Was moving all my controls around seeing if everything was working ok. I thought maybe my elevator was sluggish. then in about two min. of moving surfaces my receiver battery was completely dead! Plane has sat for a few months uncharged. Maybe unwise to field charge it? put a battery on a wall charger and changed plane battery the following evening. Tested surfaces again, battery seems to be holding up fine, put my meter on for a load to drain it again, took quite a while to come down.Makes me wonder if battery was damaged from crash? Maybe it wasn't pilot error( crash ), could have had enough power for range test, then take off but not enough for complete flight + a dead stick in the sun.Ailerons and rudder move way faster then elevator or mabe it was always like that? maybe binding or bad servo?Hmm think I'm going to the basement to check for binding. Opinions appreciated thanks.
