Argh! This one is a bit frustrating

Up until yesterday i had no problems at all having plenty of power to take off with my Piccolo ECO V2. Im using 1 lithium-Ion pack (the long flight upgrade which should give 30-40 mins flight time) and the standard NIMH pack that comes with the kit (-+7 mins. FT). I've been storing both batteries either fully or mostly fully charged (when I empty one of them i put it back on the charger till its charged and then let it sit). The Lith-Ion pack because of its longer flight time I've been using throughout the day when i feel like playing with the heli so at times it may take me 4-6 hours to completely drain that one. Between flights it sits with the charge left in it if its not dead.

Now the problem.

Last night after emtpying both batteries, I charged them both back up and now the heli wont leave the ground. It will get light but wont leave the ground. The motor and rotors sound and look like they are pushing the same RPM's (cant be sure of this) but it just wont leave the ground. I've added no new pieces (weight) since the recharges and have had no major crashes (damage). The rotors are brand new. The thing just doesnt want to leave the ground anymore

Can anyone offer some advice?

Scratch that Figured it out. Should have listened for a difference in sound. The bearings for the flybar on either side of the rotorhead had come out of their seating. That will do it i guess
