RE: Double Horse 9053 Helicopter
9053 is not really suitable for outdoor flight - however you can make mods to assist
Add counter weight (a coin for example) to inside noise cone stops the backwards tendancy during take off
trial & error to find sweet spot works
Tail rotor blades are too small - replace with Sky King #8500 rotor blades, you'll need to "trim" clearance on rear 9053-19 Balance stabilizer too
Replace metal 9053-01 Balance bar with plastic one from Double Horse Balance Bar 9060-01
Upgrade battery to 2200mAh
Grab several parts cos ya guna need them with running repairs
