<DIV>I have been testing one of the new Jeti Spin 75 controllers and it records
max rpm, max temp of controller, max amps, min voltage and a few other
things. Works well, easy to use and doesn't weigh anymore than it's
predecessor, the Jeti 77. It doesn't give you any ability to see
continuous values for the entire flight like the Eagle Tree, just minimums and
maximums and controller temps, flight times, etc.</DIV>

<DIV><FONT face=Arial size=2>I've got quite a bit of in-flight data from the
full blown data logger with telemetry. It is an excellent way of keeping
track of your batteries especially on a new plane. I had a helper
watching the mAh used while I was flying so I wouldn't exceed 80% of the
capacity. After a number of flights I found the consumption was very
consistent from flight to flight and I eventually could see I could
depend on time of flight to predict battery usage. The peak current is
normally slightly lower than that during the run-up on the ground before
taking off. The current graphs are very interesting. I find I'm
only over 40 amps for about 8 seconds at a time and then well below 40 for the
next 10 to 30 seconds. The average Watts during a flight is about 900 so
the motor and ESC stay quite cool. </FONT></DIV>

like a good way to track how much of your batteries you are using in
flight. I'm also wodering about if there is a significant difference
between current measured on the ground and in the air.<BR><BR>Ed<BR>
