      SAFETY  Does your DX6 or 7 have a very sensitive throttle on starting to spool up
I have come across a few Spektrum DX6i and DX7 Transmitters that seem to be very twitchy on initial movement of the throttle stick, which makes them a little dangerous for as soon as you touch the stick, the helicopter starts to spool up.

There are of course several reasons for this, the most obvious being that your throttle curves do not start at ZERO%.  The second reason can be because you have not let your ESC "learn" the min and max throttle positions (assuming your ESC allows this, - most do)

However, if both these are correct, you can still find that the Tx is very twitchy about throttle.

A useful way to adjust this that few people seem to realise is to use the throttle settings in the SUB TRIM menu of the Tx.  If you adjust that value down so that it is has a left facing arrow (eg <-20), this will move the entire throttle range downwards a little bit, which means you will then need to move the throttle stick a bit MORE before the helicopter will start to spool up
