Group,
 
    Thought this would be of interest to those of the group flying ahead or behind an "IVO" prop.................Thanks to Kenneth Johnson
for pointing the way to this information.............
 
   Go to "Matronics" archive http://www.matronics.com/search and search "IVO prop motor current limiter and electronic CB report"
for a list of posts leading to a current limiting circuit design by Bod Nuckolls which was built by another list member and apparently
proven to work satisfactorily................Below is a link to the circuit design and photos of the packaged assembly................You need to
read all the posts of this thread to gain all the necessary info on adjustment made to the circuit when installed (they were minor)....
 
  I have not found any further info on the design of the electronic CB described in the posts by Bob Nuckolls so far.................It was to
be done when at a later date when he had time..............

Hi All,
In June of 2010 AeroElectric began a discussion on a simple wiring system to turn off the ivo prop motor when current progressly increases as the motor reaches the end of its run.  This might be an alternative to the amp meter.  Ken Johnson
