ISTR that with both engines lit, the EZ-Rocket _has_ to fly in a
Theoretically, yes. In practice they'd never *quite* spin at the same
rate. At these
kind of rotation speeds even 1% difference is 1000s of rpm. Plus, this
current
design of engine isn't throttleable but variations on the design of
course could be.
Still, the potential for SSTO is there with a

As with Roton, in principle all you need is an electric motor p
I think it's about time for us to set up a lunar colony.
For practice, first let's set up a hypothetical one. Certain ERPS members have the
following moon-ish domains: (let me know if others have them and want to participate)

With an even number of engines, you could handle all your roll control, at least when
you're under power, with brakes: apply the brakes on one or more engines, and it will
apply a torque to the rocket.
With an even number of engines, you could even handle an engine out scenario by
applying bra

At these RPMS would there be enough force to torque a frame? Any frame just
enough... I'm thinking of gyro forces acting at a right angle.
Wouldn't weather cocking start a progressive corkscrew?
