If you are still a little shakey doing loops and
stall turns, GOOD. If this was 'easy' more people
would be flying Helicopters.
Rolls are probably the most intimidating of the
basic manouvers. Questions about roll rate, revo
settings, and sustaining head speed at negative
pitch settings SHOULD be on your mind. If you have
come 'this far' it is time to just GO FOR IT.
Your basic setup should now be pretty close to
ideal for the 'Idle Up 1' mode. Fine tuning will
NEVER end, and finding a new twist on setup is the
name of the game.
When doing your first roll, the Key is keeping
FORWARD speed up. Keeping head speed high when going
to negative pitch has been taken care of with your
setup by now.
Unlike an Airplane, you do not have the luxury of
having a constant source of power pulling you
forward. The Heli depends on INITIAL forward speed
to complete a roll. So we CHEAT a little bit. Just
go into a shallow dive. First time it will be scary,
but started high enough, you will survive. Just DO
NOT do what the Aircraft guys do and start the roll
climbing even a little. As long as you maintain
forward speed, all the little fears about Revo
mixing, roll rate, etc. will disappear.
Note*** A heli's forward speed is a function of "verticle
lift" and "disk angle", sort of like constantly
sliding 'down hill'. When entering a roll, the heli
should be in a 'Nose down' attitude, generating
verticle lift and forward speed, as the heli rolls
to inverted, the applied negative pitch and
"maintained" Nose down attitude will make
consecutive rolls possible with a little practice.
The tails attitude (slightly high) will be
maintained throughout the rolls without any control
input to the T/R. (assuming a half decent revo
setup). Plank flyers will find doing consecutive
rolls almost as easy with helis, only difference is
pumping collective instead of elevator.
Rolls can be done 'with the wind' or 'into the
wind'. With the wind they will look smoother but
started late, the heli may be a long way out before
completion. Done into the wind, the roll will look
'pitchy' and erratic but will not travel as far.
Having said that, I don't think it matters much.
Lets Get Started....
Just sit down and think about the sequence of
controls for a bit and do some dry runs with your
thumbs BEFORE attempting the roll in the air. As
long as you do not panic you will pull this off with
no sweat.
For the faint of heart, start as high as you can
and as fast as you can. The rest of you just follow
these simple directions.
Make a big sweeping turn at the end of the field
to conserve forward speed. Settle into a fast level
pass at full throttle/collective, making sure you
are NOT climbing. The faint of heart should actually
be decending very slightly to come back into sight.
OK NOW...
Your level, your fast, the heli is right in front
of you, your heart is pounding, Give it full
aileron...Jeez, it seems slow doesn't it?...Can't
fold now, in for a dime, in for a dollar.
As it starts to roll, you should remember to give
it full 'negative' collective (all minus 2 or 3
degrees), you can slam it this time, and work on
technique in the future. It WILL come around, and it
will NOT loose much, if any, altitude. As it starts
to return to right side up, give it positive
collective again and release the aileron when level.
The roll probably looked better than most
aircraft rolls. With a bit of practice they will.
It won't be long now before you are trying
consecutive rolls, split 'S's, Cuban '8's, reverse
inside loops.....watch out Curtis Youngblood. |
