Hey want to change my battery pack...... Bought my plane earlier this year and tried several times to fly that thing but it won't go up.....will it be a battery problem or the charger problem? Plzzzzzz suggest iam a beginner 

Which is your plane and what exactly is happening if you try to fly it?

What's the battery voltage , capacity, type?

Try to go up but the head drops down

It's a 7.4v 360 mah nimh 2/3aaa

You can get a 2S LiPO of around the same weight of your NiMH pack.

But the actual problem of your plane may not be the battery, so Post clear pictures of your plane and also which model it is.

Which is your motors and props, and if this is a ready to fly plane bought from retailer, specify the model name of your plane too.

A battery won't always be the issue for a plane not taking off.

Four engine low wing bomber!!! Although I may be a noob but I am pretty sure...

That battery (7.4v 360mah) would work great for headlights on that setup!!
