No, no, it's clean I promise.

Don't worry about my mate who thinks I am going to hit some poor dog walker. I missed him by at least 20 metres. He does get a bit exctited my mate. Bless 'im.

How do you get it upside down, Surely the rotors would push it down towards earth...?

Re: Playing with my chopper.
 

nice, someone's been practising ;), out of interest are you mode 1 or mode 2?

its called collective pitch, the blades turn at a constant RPM but the blades move individually to make the helicopter go up of down, like a elevator on a plane. hold the throttle gimbal at the bottom and the blades angle to push the air up, hold the throttle gimbal on full and the blades angle to push the air down

Re: Playing with my chopper.
 

ahhhh that makes sence... duh! lol

Re: Playing with my chopper.
 

Hee hee. Yeah, lots of practice. Started heli's in Jan this year so am quite chuffed how things are going.

Yep, basically you change the pitch of the blade so that it blows the other way. Ooeer! :rolleyes:

Oh and mode 2 (left throttle) all the way!

Re: Playing with my chopper.
 

well some helicopters have fixed pitch which is what you think of, the blades dont move so the helicopter cant go inverted or it will as you say hit the ground lol.

some planes use variable pitch props that work on the same principles as collective pitch

lol i am such a nerd :p

Re: Playing with my chopper.
 

ahh ghey mode 2'er ;)

Re: Playing with my chopper.
 

you obviously don't fly remote control stuff in Scotland! think everyone I know flys mode 2! the best laugh I've had in ages tho is indoor flying. small foam/polystyrene planes and a big gym hall makes for a great laugh!

Re: Playing with my chopper.
 

its the yanks that invented mode two, mode one 4 eva!!

we do that in winter, higher out a local vellodrome (sp) and smash teh sh!t out of each other, never had such a laugh

Re: Playing with my chopper.
 

I don't know anyone who uses mode 1. Everyone I know uses mode 2. So you're the weirdo! :D

Yep, fixed pitch the altitude is governed my the speed at which the rotors spin. If you want to go higher, increase the throttle. Want to come down? Reduce the throttle.

Collective pitch is where you change the angle of the rotor blade. So to go higher you increase the pitch of the blade, want to go lower, decrease the pitch of the blade. This means you can set the throttle to something constant and just use the pitch to control your altitude. Collective pitch heli's also have the added bonus of being able to autorotate. In short, you can turn off the engine and still be able to land safely and under full control.

Yep, me be a heli-nerd!! :smurf:
