I just got my Lama V3 in the mail today and while charging the battery I was reading through the manual and I dont quit understand some of the terms. Could really use your help.

Two things I need help with. Understanding the Proportion Trimmer and the Gain Trimmer. What would the heil be doing in the air for me to have to adjust the Proportion Trimmer and also the same thing for the Gain Trimmer?

I charged the battery for about an hour and flew the heli for about 5 minutes to make sure everything was in order. All seemed fine, but the heli keeps wanting to lean to the left and come back a bit. Also turns to the left a bit as well. What do I adjust on the 4-in-1 to balance this out? please help anyone. Thanks, Joe
