LEARNING TO DO ROLLS
**NOTE** REMEMBER! THESE ILLUSTRATIONS ARE
TO GIVE YOU ONLY AN IDEA OF WHAT IS TO HAPPEN. YOU NEED TO BE MUCH HIGHER
IN ALTITUDE BEFORE TRYING ANY AEROBATICS FOR THE FIRST TIME. USE EXTREME
CAUTION AND HAVE AN INSTRUCTOR THERE WITH YOU AT ALL TIMES. ALSO THESE
ILLUSTRATIONS AND LEARNING TECHNIQUES ASSUMES THAT YOUR HELICOPTER IS
SET UP TO DO THESE AEROBATICS. MAKE SURE YOUR MIXES AND COLLECTIVE IS
SET CORRECTLY! GET AN EXPERIENCED FLYER TO CHECK THEM OUT AND DO FEW FIRST.
Like learning the loop, to learn the roll you will probably just give
full right cyclic and let the helicopter "fling" its self over
to the right. Helicopters that have clockwise rotation (looking down from
the top) usually will roll to the right easier. So do them to the right
to start. I have noticed that rolling to the left takes less negative
pitch to do but usually feels kind of weird to me... maybe its because
I'm right handed. As with the loop, the faster you go into them the less
negative pitch you need when your inverted. You should start with a good
normal speed going into them.
Photo #1
 
Photo #1 shows the helicopter flying straight and level from right to
left. Unlike a roll you should do the roll down wind. This will keep you
from running out of forward speed. For contest style rolls you will want
the point where the helicopter is inverted to be right in front of you.
You will also want the last part of the roll to be the same length as
the first part of the roll. However since these are your first rolls do
them as the helicopter passes you. This way your behind the helicopter
again if any thing goes wrong.
Photo #2
 
Photo #2 shows the helicopter on its side. When the helicopter is on
its side you want to be about 1/4 throttle stick or where your 0degres
of pitch is. This way the helicopter doesn't push in towards you if you
have to much positive pitch or pushes away from you if you have to much
negative pitch. Usually this is minimal if you have good forward speed.
Also notice that on the radio your not pushing the right cyclic stick
any more. You have backed off it. Its a good idea to do this because when
your inverted your not pushing the nose of the helicopter up. In fact
after you learn to do rolls and want to do slow rolls you will have to
start pulling the stick back some.
Photo #3
 
Photo #3 shows the helicopter at a full inverted position. Here you are
at full negative pitch. However depending upon your forward speed, you
might not need full negative pitch. Just enough to hold the helicopter
level. Again, you might need to pull some aft cyclic to bring the nose
of the helicopter back down. This is more so if your trying to do slow
rolls.
Photo #4
 
Photo #4 shows the helicopter back on its side. Just like in Photo #2
your back up towards 0degree of pitch so the helicopter will not blow
into or away from you. Just a note: if your tail rotor mix is off you
will see it in photo #2 and photo #4 the best. The tail rotor will either
push the tail towards the ground or up and you will or can get a "cork
screw" type roll. However!!! if you are just off on the collective
stick with your timing... you can get the same signs...
Photo #5
 
Photo #5 shows that your roll is done. It has finished hopefully at the
same distance from you it has started (GRIN). Your transmitter sticks
are now back in the forward flight position.
Well ...that's it... good luck... Its pretty easy if your high enough.
