Fly Bar Mod for
Lite Machines
helicopters
All of these mods may have some risk of damage to your helicopter parts. I
can not be held responsible if you do any of these mods and they do not
work out for you. So do them at your own risk. I will also not be responsible
for any injury or damage to you or your property or any one else.
This mod to the fly bar is best done after you get into forward
flight.
It helps stop the pitch up condition of the helicopter when
you are flying around. When you fly your helicopter you may
have noticed that it tends to rise up when you try to stop at the
end of a flight. This is due to the lift of the fly bar. To stop the
pitch up condition all you have to do is heat the fly bar a little with
a heat gun like the ones used for hobbies. Do not get it so hot that
you melt the plastic. Once it is hot enough, you will be able to
bend it to remove all pitch angle from the fly bar, making it nice
and flat. You do not have to get it that hot to make it hold its
shape and you do not have to heat the blades to bend it. Only the
thinner middle section needs to be heated. This one makes a big
difference in how your helicopter handles. A must do mod.
Thanks to Matt from Ballistic Technology for
sharing that mod with me some time ago on
RCGroups.
