I was flying my Lama V4 in slight breeze and a few minutes into my flight it started losing power like it was at the end of the battery. I also noticed that I had the left stick all the way to the left. I put in a fresh battery and the same thing happened but in less time. At first I could lift off but I had to give it more and more left stick and had to keep increasing the throttle. I brought it inside, took the cover off and checked the gears because this is similar to how it acted when I striped one of the gears. But they were alright. I tightened everything, put it back together and tried to fly it again. The same thing happened. Iā€™m thinking that one of the motors is losing power for some reason.
Anyone out there had this problem before?

The brushes on one of the motors could be getting low.

The motors are only about a month old. But it's certainly worth checking out. Thanks.

my friend has the same bird.. one of his motors went out in two weeks.. he had the same problem you are having.. he changed out the motor and it works great now.. actually better!~! jake.

I ordered a set of brushes for each motor. I guess I need to give the motors more time to cool down between batteries. I have heat sinks on them but the heat sinks seem really small. I may add another heat sink on each motor. Also, Iā€™m thinking about getting the Xtreme Sport Conversion. That should provide more air flow.

Just an update. I finally got the brushes but they did not fix the problem. I ordered a new motor.

For anyone that may be having the same problem, the new motor fixed everything.
