WLtoys V977 Power Star X1 - Fix for not enough lift HD

Beginners should probably watch this video. This is a very, very common problem that occurs after a very light crash, then the helicopter requires a lot of throttle or collective to lift off. Reason: Main shaft is able to slide up and down. Fix: remove the slack between main gear and main shaft by pushing the main gear up. Hope this repair tip helps! • Review: http://www.rcgroups.com/forums/showthread.php?t=2110411 • Metal head upgrades: http://www.banggood.com/WLtoys-V977-V966-Metal-Conversion-Upgrade-Component-Red-p-943625.html?p=541709059675201205AM • Red canopy and rotor blades: http://www.banggood.com/WLtoys-V966-V977-RC-Helicopter-Parts-CanopyMain-BladeRed-p-935425.html?p=541709059675201205AM
