How to do a roll?

[mousie]

Ok I been flying my exi 450 and run through about 30 packs with no crashes.I have my radio set with 10 degrees+ at full and 5 degrees +at mid.Do I need - pitch to do a roll and what is the best way to try this procedure. Any help from you stunt jockies out there would be great.

[Gabe]

Yes!

You always need negative pitch when doing anything inverted. You will want a full positive pitch in your idle up/stunt mode along with full negative pitch as well. This is typically in a range of +9 to +11 and -9 to -11.

You will also want your aileron servos on high rates.

To do the roll, take the 450 up high. My first one was comfortably accomplished a little higher than a telephone pole. I'd also have her about 20 yards in front of you. You don't want the bird right over your head or you'll lose orientation.

When your hovering tail in comfortably, give the left stick just enough positive pitch for the bird to start rising, and simultaneously push your aileron stick (right stick) full right or left. As she starts to go inverted, slide your throttle below mid stick and hold it there so that the bird doesn't lose altitude - all while still holding your aileron full right or left (whichever you originally chose).

Now as the bird starts to come out of the roll, start bringing the throttle stick back to positive and release the aileron as she finishes the roll.

It's a very easy move but I would still recommend trying it on your simulator first.

Ok I will try to figure it out on my TX, Not sure how to set it up for stunt mode. Its a DS8000 Airtronics and Iam new to CP helies.How does - pitch work do you need to switch to stunt mode after you get it in the air and turn it back off to land? Not sure I understand the whole idle up stuff.

[Gabe]

I did a good write up on stunt modes at one point. I believe it's either in the glossary or it's in the advanced section. I'll see if I can find it and link it.

[mousie]

Thanks Gabe I will keep an eye out for it.

Also, if you do a fast forward barrel roll, you don't need much, if any, negative pitch.

Get going FAST in a straight line. Give it a little up elevator where the heli nose rises, then hit full aileron, right or left. As it goes inverted, reduce the pitch to zero. Apply pitch and let off the aileron as it finishes the roll.

Note that for any of these maneuvers, you need stunt mode enabled with throttle always on. My throttle in stunt mode is always 100%. This is when you need to learn to use 'Throttle Hold' if you get in trouble.

As Gabe mentioned, it's a very good idea to practice on a simulator first. It's safer! I had my worst crashes when learning to do some of these strunts. I didn't use the sim enough. But once you learn them, they are FUN!!

Good luck!

Well, it's not a "set up" post like I thought I was, but here is the excerpt from the glossary:

Normal Mode (Submitted by: Gabe)
Throttle response and head speed (rpm's of the blades) is directly linked to the position of the left stick. The pitch of the blades will always be positive once the heli has lifted off the ground. No inverted stunts are performed in this mode.

Idle Up/Stunt Mode (Submitted by: Gabe)
Typically linked to the GEAR switch on most radios, flipping the switch to idle up (or "1") will lock the head speed at a set RPM. This is typically 90-100% of the maximum RPM of the motor. In this mode, when the throttle stick is at the center or neutral position, there is 0 collective pitch and the heli should hover. When the throttle stick is at it's full down position, the blades will have full negative pitch (typically 9-11 degrees). When inverted, the heli will gain altitude with more negative pitch. When right side up, the heli will lose altitude with more negative pitch. When the throttle stick is in the full up position, the opposite will occur. Right side up the heli will gain altitude and vice versa for inverted flight.

ive found everything is easier at speed. rolls flips and loops. seems when things go bad i can recover during speed attempts than stantionary.

i like going fast into steep stall turns drop the stick to 1/2 or almost and do falling flips , this way your high 40-60 ft up and you see whats happening with left stick imput . youl see the falling flips turn to tighter stantionary flips with the right amount of left stick along with right stick.

i recently got the real flight sim and my flying is improved 100% im now flying the nose dang near as well as i fly the tail. the sim realy is priceless. i recomend 20 hours on the sim practicing everything all oreintations before doing the real thing.

made this vid on the sim that shows the sticks durring the flight. mayve someone else who flies better could make a similar vid

im not very good at rolls seems i get alot of noseforward on the stick
