[NSRCA-discussion] Rules change proposals

[Keith Hoard]

I just added some down thrust to my plane, is that illegal?

Scott, I don't want to beat this to death but you must be very careful.  I
could interpret this to disallow Contra Drive prop set ups that
automatically cancel the effects of spiral slipstream, torque, gyroscopic
precession and P-Factor.  What about adding aerodynamic appendages that
improve stability and damping?  It is not clear why the aerodynamicist
should should be given an advantage over the power management guy or the
electronics guy.  I'll never understand why the variable thrust alignment
system was disallowed.

I don't really care what is decided, but if the rule is not well defined it
will cause turmoil and new guys thinking about getting into pattern won't
like it.

Good Afternoon,
   First, let's agree that "Engine managment" was not a correct term that
we derived from the "old days" and we will fix that (per John Fuqua)
assuming it passes the initial vote.  Second, let's not lose sight that we
are speaking about telemetry and we are speaking of automated functions
here, not those that require direct and manual input.  The wording is such
that engine management systems that COORDINATE (through telemetry and read:
automatically adjust) power output (to maintain a speed or anything that
may relate to) with model performance, position, or attitude.  Honestly,
this is no different than a gyro correcting attitude and we certainly don't
want to allow that.  We simply are trying to allow telemetry that is
important for safety and continue to dis-allow anything that automates
flying the aircraft.  In my very humble opinion and to answer your
question; Yes, I think we do want to outlaw something that makes our models
fly better IF it is automated and not pilot-induced.
