Problems with my blade 120SR

[bixlertje]

I have flown my helicopter for 3 years now. Last week I bought a new battery (the Original from e-flite 1S 3.7V 500mah). Wen I want to fly with my new battery my helicopter stop flying after 2 minutes. I took it from the ground and gave throttle again and he flew again for 3 minutes. What would be the problem?

My second problem is how to trim my helicopter because if I want to go forward he will automatic go to the left

I just picked one up and have been practicing hovering (noob heli driver here) and noticed that mine drifts to the left too. I have tried to trim it out but as soon as I think I get it, I swap batteries and start over. I was able to find the balance for the batteries but am thinking about going over to my LHS and asking them if it's operator error or if maybe one time when it bashed against the house I messed something up.

If I could just get it to not drift right I think I could get it in a "near" hands off hover.


As for your battery problem make sure the battery is securely connected and also doesn't move in the battery holder. I picked up a bunch of batteries and noticed that maybe 80% of them needed something to make them fit more snug in the battery holder.
FYI I am only getting 6 minute flight times but that's because I am trying to respect the 80/20 rule. After flying my batts are reading between 3.7-3.8V
