My 4-blade set shipped on Aug 13. At least I hope they did. I am going to give them a month.
In other news, I received both my tail pitch arm from microhelis.de last Friday and my CopterX 4-blade head from ehirobo yesterday. Both took about 3 weeks to get here from when I ordered them.
I am pretty impressed that for $117USD (that includes shipping) I got the 4-blade rotor head, a swash plate, main shaft and collar, swash follower and links. I was just expecting the head by itself!
