those mixing armsI have two v120d02's. Those mixing arms are so fragile they can, and will, fly apart in mid-flight. pick up a supply of them, and a bunch of the front taildrive gears, which are also fragile.
or, instead upgrade both parts of the heli
I highly recommend Heli-worx V1 FBL head
and their 48mm titanium main driveshaft.
the drive shaft is out of stock right now. it is required form the head.The V1 head has no mixing arms.
and it is great. you will need no other parts other than these to upgrade the crappy walkera FBL head.
the front taildrive gear can be replaced with a metal one by emailing wolfgang at email@example.com
. just inquire about his metal gear for the v120d02.
these two upgrades will make your new heli a joy to fly. without these upgrades, in my opinion, the heli has serious drawbacks. Replacing that front gear will drive you nuts. Its the first thing to go in a crash. its not easily replaced. and those mixing arms are a joke.
