I have been asked me to clarify the 640g all up weight claim that I made previously.

640g all up includes the Drive, a modified Kontronik 650 Pyro motor, (extended shaft and extra front bearing...) the rear support, front and rear spinners, and front and rear props with prop nuts.

It doesn't include carbon fiber plates, (fuselage plate and motor plate) or the Budd rubber mounts.

We are also looking at the Kontronik 600 Pyro motor, which would save an additional 70g, but it's only rated for an 8s pack, so we aren't holding our breath.
