Default Big Lama upgrade

First post!

I just completed the Esky Big Lama upgrade.
Parts added;

15mm extended inner shaft, aluminum swash plate and lower blade mounts, black, Xtreme hardened upper and lower blades.
I also moved the battery forward about a 1 1/2". In doing so I had to adjust my flying as it now tends to pitch forward upon lift off rather than simply hovering which was the intention for outdoor flight anyway.
Just to let some of you know that if you decide to replace the stock shaft with the extended one it would be prudent to also purchase the aluminum blade holders. The original lower, plastic holder has two screws set into the shaft and the plastic threads strip as soon as you remove the two screws. You'll never be able to fly as the lower blades will just spin on the shaft and will not counter act the torque of the motor. Your helicopter will not lift off and will spin in circles on the ground!
I also snookered myself with the extended shaft as I cannot use the upper aluminum blade holder without losing the 15mm extension. I had purchased everything from ESky helicopters.com. The extended inner shaft is a little different than other aftermarket parts suppliers so if I add the aluminum upper blade holder I lose the 15mm extension. Oh well, the plastic upper blade holders in in perfect shape.

I have to say that the Xtreme blades are way more resilient than the stock plastic blades. I've whacked a few trees in the back yard and they don't have a mark. The Stock blades would have broken or split at that point. Their larger surface area provides a lot more lift too!

Anyway I have a question to add.

I also upgraded to the 11.1v Lipo battery. I continue to use the balancing charger that came with the Big lama. I rarely use the helicopter so the battery stays plugged in all the time. Is this the wisest thing to do even with the balancing charger? Once the battery is fully charged should I disconnect it from the charger or will it go flat over a period of several weeks? I know that if it drains all the way down it is toast and has to be pitched.
Thanks
