WLtoys V912 eight upgrades. Very simply, effective and cheap.

Here are eight mods of WLtoys V912: Speed and Agility 1. Shorten top of Main Inner Shaft SKU056689 (lower the aluminium cover) to prevent flybar from tail and canopy strikes. 2. Bent Balance Bar horizontally SKU055997 for reducing bell rotor head and gyro effects, it means better aerodynamics and agility (This is the best option from all I&tested , including shorten weights arms. The worst was bent weights up, because very unstable) 3. Remove Tail Strut for better aerodynamics and for improving the center of gravity 4. Upgraded Battery 7.4V 1000mAh 25C 61 g SKU067026 - 6.01€ for improving the center of gravity and for longer flight 5. Red back light SKU127984 – 1,40€ for better visibility and orientation in second socket (just soldering red high light diode) 6. Battery low voltage Alarm SKU006458 – 2,10 € for safety landing and for improving the center of gravity 7. Transmitter mod for pernament servo ultra setting (accelerate button replacement) - speed and agility 8. Twist the tail fin around the bottom screw a little bit forward (and drill new holes for the upper screws) for preventing tail propeller strike ground.
