I was given one of these a year ago and tried to get it to 'fly' last night...with the body in place it will not climb, remove the body and it does a poor imitation of flight.  figured I'd replace the battery and found some 3.7v 150mah batteries  on eBay.  there seem to be a variety of types of the same voltage but  differing in the number of cells, either 12C, 15C, 20C or 25C. I presume this refers to the number of cells in the battery.  anyone have any idea as to which might be better? probably not worth the effort but the grand-kids might enjoy it...

Any info of the type/brand helicopter? 

If it is having trouble flying with the canopy in place, it is definitely going to be a weight/power trade off.  I believe the number of cells will just extend flight time, but you want to keep that down to a certain degree to even get it to loft.

I believe the 12C/15C/etc. refers to the discharge rate of the battery.. the higher the # the higher the discharge rate.

Try a Blade.
They cost a bit more but they're much better helis.

First, I know nothing about helicopters, but I would check the drive gears for binding first. A small alignment problem could be sapping enough power. A trick we used on slot cars back in the day when we couldn't afford top quality parts was a bit of toothpaste on the crown and pinion gear and run them in for a bit to match the gears.

+1 on blade mcx. I have two. Now I want a better controller. I have bought a bunch of junk helis, these are the best bang for the buck.

Toothpaste? As a diehard slot car guy back in the day, valve lapping compound was better. Wound my own armatures too.

More on topic, mike is correct, check for binds in the gears, alignment is key. Also try electronic spray cleaner to clean the general funk off the gears, just make sure it's plastic safe.
