RE: Gyrotor indoor/outdoor Heli
I had the same problem with my Gyrotor. I used WD40 and a tiny needle to remove the clump of hair.
My Gyrotor flies perfectly. I found the key to flying it, you have to turn off the helicopter and remote control, then set the trim setting on the control to about center(This way when you adjust it during flight you don't run out of trim radius.)Turn the control on first(critical)then the helicopter second. Fly the helicopter low until you get the trim set right, make very slight adjustments, oversteer sends it out of control every time if you do it fast. One thing you have to understand is that it takes more thrust and more battery to turn left, that's why when you circle left it usually plummets. When you turn right the rear motor uses less power, therefore the main blades get more power, that's why it goes up. You'll probably experience the heli spinning right later in flight uncontrollably because the battery is too weak to spin the rear tail rotor fast enough to turn left.
