Roll in forward flight
During forward flight, do I need to give negative pitch when the heli is upside down during the roll, or do I just apply left or right ailron to roll it without the need to worry about the collective stick?

You need to apply negative. You'll find the cleanest roll will be performed by bringing the collective to neutral while the helicopter gets started in the roll at the first ninety. Use a little negative when upside down, go back to neutral at the next ninety and normal positive when it is upright.

It should be a continuous motion with the left stick from positive to neutral to negative to neutral and back to positive. All of this correctly timed while the helicopter rolls. Same thing with 4 point rolls but you hesitate accordingly with the collective at each point.

If you have a slight nose down attitude when you start, you should be able to maintain speed through the maneuver. If the helicopter slows down, you may need to give a touch of back cyclic when it is upside down. Not to much though or you will dive.

Your bailout plan when you first get started should be to immediately roll upright and add positive pitch once there. Keep the collective near neutral while you get it back in control.

So that means it is the same as a stationary roll.

If the pitch remains positive or neutral throughout the roll, will that become a barrel roll?

Yes and it will probably descend rapidly as you roll over.

I have found that the more speed you can get, the cleaner and tighter the roll will be... ImoT-rex 600n super pro , Trex 450 se, Gaui 200, Trex 500, Blade cx, . "If ya plant corn, ya get c

When I started doing them I couldent get it to not corkscrew, I found pauseing while inverted for a breif second seemed to work.
Also I was trying to get em right for a couple of weeks with no luck, I accidentily flipped over the other way to what I was used to in a nervous moment and to my surprise the roll came out perfect.

I think you will find that if you hit 0 while rolling, you should be fine.It's a complex, costly, glow powered anti-gravity machine!

Also worth mentioning that a poorly balanced heli can make an clean axial roll much more difficult. I had never really been to critical of balance until I began rolling/inverted flight. It makes a huge difference.

Keep the nose down when initiating the roll else it may corkscrew into a strange attitude that can be dis-orienting to recover for a newer pilot!!
