[NSRCA-discussion] Plettenberg 30-10 evo and Jeti ESC

Hey Ron, the answer is truly I don't know, all i know is that once i changed
out the receiver, all the problems went away.  the receiver came with the
18MZ

Wait a minute. "The problem was with the receiver." doesn't quite cut it.
What was the problem?  

I'm glad you got the problem "solved", but you can't trust that receiver
until you identify the problem.  BTW, "I don't know" is a perfectly valid
answer, but you could save somebody else a lot of grief if you know what was
wrong with the receiver.

Well I think I found the issue with the Jeti and the Plettenberg.  The
problem was with the receiver.  I recently got a new radio, and installed
the new rx in the plane, and then the issue started showing up.  I even went
and borrowed a Jeti99Spin, to see if this would resolve the issue, but it
did not, so I started to think of everything that I had changed, and decided
to go back to my 8 channel receiver and voila, everything is back to normal.
Thanks to everyone for there input.  Feels good to have the problem behind
me

My suggestion to limit throttle isn't to limit current draw.  It's to limit
the motor RPM's so the ESC can remain synchronized with the motor.  If the
motor turns faster than the ESC can handle, the motor will begin screeching.
I've only seen this on outrunners, never inrunners.

That was my thought. I don't understand why one would want to limit the
throttle to something less than full. Why not install a prop that loads the
motor less?

Limiting throttle does NOT limit current to the motor, in fact, it can cause
higher current draw.  All throttle does is vary the on vs off cycle during
which voltage is sent to the motor.

Hi Rob, the Static amps on the ground is 81 amps.  My throttle is limited to
85 percent.  Even changed out the speed controller and the same thing
happened.   Really wish i knew what was going on?

Robert,

Which Jeti are you running?  Advance or Spin?  Just a guess, but all the
outrunners I've run require low timing advance and some require fixed end
points and the throttle to be limited to 70 percent or so.  Also, have your
checked your set-up on a watt meter?  Sometimes our set-ups pull more
current than we were expecting and the ESC over current protection kicks in.

Hope this helps.

Rob

Is anyone out there running this combo.  Went flying today, and had some
issue with the speed controller cutting out when i was setting up for my
approach into the pattern.  I was pulling up and advanced the throttle to do
an reverse cuban eight to get into my pattern, when the motor suddenly quit.
I pulled the throttle back and advanced it once again and the motor came
back it did this on every flight except the first flight where i had no
issues whatsoever.  my setting are high timing for the motor, low cut off
voltage, acceleration high, 

thnaks in advance
