I neglected to mention that the AUW of the Cirrus flight pack (RX, 2 servos & ESC) is under their advertised weight at 9.5 grams rather than the 10 grams they state.

As Micro Builder, probably knows, I am not a fan of the other gear you asked about. I feel it is too delicate for most people, the thin PCB is easily breakable, soldering often shoddy, leads are single-strand Litz wire rather then the twisted multiple strands other actuator mfgs use and very delicate (breakable), assembly of smaller moving parts is often poorly accomplished, the magnetic battery connection causes problems, and their return policy is not free... When you happen to get a good set, it does perform as advertised. It is suited to peanut sized models.
