[wunderbar]

i would recommend to anyone if your flybar or tailboom breaks, try to find a metal replacement.

i have stainless steel "hypodermic" tube for the flybar, and aluminum tube for tail boom. way stronger than the carbon (won't crack), and if somehow you do manage to bend it, you can bend it back..

also the set screws for the flybar paddles & tail holder / chassis will hold much better on metal than carbon. i think that's a bad design in general (set screw into carbon rod) - the screw inevitably splinters the carbon.

you really need steel for the flybar, and ideally precision tube which is lighter & stronger than piano wire.

mcmaster.com sells hypodermic tube in the sizes you need - 19ga for flybar and i think 13ga for tailboom. i'm switching to stainless for tailboom too (bends less than aluminum).

this weighs a fraction more, and costs more but still cheap.

they are the best improvements i've done to this heli.

that & the plastic stir straw as antenna tube, which i'm pretty convinced reduces radio glitching. you fold the antenna wire up (1/4-lengths are ideal i think) and slide the bundle in the straw, then attach to landing gear w/ fishing line or whatever.
