help... new raptor g2
when i try to power up the tail blade spins but the main blades spin really slow.. causing it to spin out of control. i tried powering it up before and it spun fine. what can it be. im new to rc and im in new york city and i dunno how popular rc helis are here. im also not too familiar with the controller.. so any info would help. thanx [&:][&:]
