If you read the section on functions specifically permitted item 5
you will find:<br>
<br>
"Examples of control functions permitted:<br>
1) Control rate or control movement limit devices that are manually
switched by the contestant.<br>
2) Any type of button, dial switch, or lever control that is
initiated and terminated by the contestant.<br>
3) Manually operated switches to couple control functions.<br>
4) Alerts to the pilot through telemetry that provides a safety
function such as out of range battery voltage, current and
temperature.<br>
<i>5) Engine management systems that control RPM directly from
throttle position."</i><br>
<br>
This is specifically to allow the RPM feedback systems that are
coming. These will connect the transmitter stick position to a motor
RPM, thereby correcting automatically for different batteries or
states of charge. This was added to eliminate any question of
legality for RPM feedback to the ESC.<br>
<br>
The item in the disallowed section examples is to disallow full
autothrottle operation that might tie power output to airspeed or
other aircraft performance parameter that could be used for
feedback. This means that you cannot set up the throttle to be an
airspeed request and have a regulated speed regardless of attitude.<br>

Does that make systems such as the Hacker Senestrol system which
ensures a consistent RPM based on throttle position illegal? I

have been popular...</div>

Attached is a summery of the RC Aerobatics rules change
proposals for the<br>
2013-14 cycle. I put this together for a presentation at our
judging seminar<br>
yesterday.<br>
<br>
The actual proposals can be viewed at<br>

The initial vote ballots are due at AMA headquarters May 1
2012.<br>
Contact your AMA district contest board representative with
your concerns<br>
and preferences regarding these proposed changes immediately
as time is<br>
short. Here is a link to the contest board members.<br>

I pause before sending this fearing I may not have it all
correct. If I'm in<br>
error just delete it and accept my apology.<br>
