I was a bit adventurous last time I took my MCPx out and started attempting to fly upside down.
Although I did manage a pretty sketchy barrel roll I eventually crashed and snapped the tail boom and landing gear.
I started googling for parts and found their are plenty of upgrades available for this helicopter.
I brought a stronger longer tail boom (still and official part for the heli) and carbon fibre landing skids.
I was tempted by an aluminium tail boom but I figured this would just impart the force from a crash onto the main frame instead.
