Welcome to my
new "Tips from the Pro's feature...
will, over time, be one of the best sources for information gathered
by me from all over the world of RC helicopters. Over time, as
it grows, it will be broken down into different groups targeting
specific areas of knowledge such as Radios, Set up, flying, etc
further ado, lets get started ...
How the 2.4
GHz aerial should be used
Make sure that
you have the transmitter aerial (2.4GHz) is bent
at 90 degrees at the joint in it, and that it is pointing upwards
toward the sky if the radio is on it's back. The
signal that is emitted from the aerial is rather like a large
doughnut with it's centre along the aerial, so pointing the tip at a
model is the very worst thing you can do to make a connection, or to
Spektrum (and JR McGregor) radios.
experience problems sometimes getting these makes of radios to bind
correctly. You have to use a Bind Plug that is provided with the
radios to do this, and then depending on your version of radio, hold
one switch of\r the other or press a button on the back while
turning your transmitter on.
the Receiver just sits there flashing rapidly ? Whats wrong ?
Usually it is
because the radio is too far away for the model itself. Always
try to get the radio as close as possible
to the receiver when trying to bind. The manuals say you
can be several feet away, but that is often not the case.
sure that you have the transmitter aerial (2.4GHz) bent at 90
degrees as described in the TIP above
GROUP - SETTING THE
always a contentious area, but it is so important that many of us
could write a whole book on the subject. Although helicopters
can vary quite widely in their design and functionality, the basics
of mechanical set up are always pretty well the same.
to doing a mechanical set up
this is a point that is often missed, or misunderstood by a great
The point of
the mechanical set up has little to do with the actual flying
characteristics of the helicopter, it is all about getting the
mechanics of it correctly aligned so that the swash and lever
movements needed to make it fly are evenly distributed to avoid
logarithmic movements of the servos, tilting of the servo or swash
plate during collective movement etc.
need to have a known DATUM POINT to achieve this, and that is quite
simply a setting on any of our PITCH curves that gives us exactly
50% PITCH when the throttle stick is exactly at the mid point of
This may mean
that you have to modify one of your pitch curves to get this right,
or you may have a pitch curve that has it already.
If you do NOT
DO THIS, the mechanical set up will NOT BE OF ANY USE AT ALL ...
