Airtronics SD-10. Nothing changed but the battery and the throttle cut is once again lower than the brake engagement by A/C response. I checked my notes on the transmitter setup and the only thing I did not write down is the % setting for brake and throttle cut. All other items are written down. I will see if the program is the same tomorrow.

Mike,
What's the radio? Has it had a s/w update recently?
Would recommend that your throttle cut position is at least as low
as the lowest setting you can acheive with idle switching and the
trim lever. Keep in mind that doing this may require you to toggle
throttle cut in the event of a low voltage cutoff in order to
restore throttle authority but you will never fail to arm when you
turn on with the throttle cut active.

OK, the problem is solved, but not the mystery
behind the settings change.....
I have an idle down set that engages the brake on landing
and a throttle cut that won't let the motor respond at all
until it is disengaged. These are on separate switches. My
normal start up sequence is plug in, listen for the proper
Castle music, turn off the brake, disengage the throttle cut,
spin the motor up, and take off.
I put a normal servo on the throttle, replacing the ESC and
tried a couple of different combinations of brake and throttle
cut on/off. The throttle cut position was NOT lower than the
brake. Also, the brake moved more when toggled between the
two positions than I thought it would. I did notice that with
brake on though and throttle cut off, the trim was at the
lowest position.
I hooked up the ESC again an plugging in the batteries with
the normal starting positions (brake on, throttle cut on), the
ESC did not arm. I turned off the throttle cut and this time
left the brake on. The trim went to the lowest position and
the ESC armed. I was able to spin th motor. The throttle cut
did not stop the motor if it was already spinning, although
throttle did not respond. With the brake switch off, the idle
was quite high. This was not the way things were at the end
of the last season. I lowered the % throw for the brake and
throttle cut until I got the settings where I wanted them to
be and all is back to "normal" now, including my start up
sequence. The mystery is, why did it change in the first
place?
The only difference between this season and last season was
I replaced the airplanes battery system with a redundant one
and replaced the NiMh battery in the TX with a LiPo.
Thoughts?
Regards,
Mike C

ESC question.
I
brought my airplane out of its winter
hibernation today and simply went to test
the airplane with some new batteries. I
have not changed any ESC or radio settings
since the end of the last season. When I
released the throttle cut/safety switch
and went to spin the motor, nothing
happened.
In
more detail: I plugged in ESC and got the
normal spark. The ESC played
the Castle power tune, counted 10 cells,
but does not play the arming tune. Setting
the throttle to full (with a restrained
plane of course) did yield additional
beeps, but did not ever spin the motor. I
don't see any troubleshooting on the
Castle website, hence the post.
If
I do plug the ESC into the castle link
controller to double check settings,
does the motor have to be unplugged? I
have shrink wrapped the bullets for the
motor/ESC connection together and would
rather not separate them. I will remove
the prop, of course.

Mike
