Can someone help me?

" propellers(sp?)". It's usually spelled "blades".

Two things make lift. RPM & AOA (pitch). You have to generate enough lift to lift the weight of the heli. If you have plenty of RPM ... look at pitch next. If the pitch is at 0°, you're not going to generate the lift needed to fly the heli ... regardless of rotor RPM. If the rotor blade is flat bottomed air foiled in shape, you may make lift but not enough to fly. What is your main rotor blade pitch at low, mid, and high collective stick. If this is a fixed pitched heli, then what is your pitch setting?

Good Luck,
d.tipton

And by pitch do you guys mean the right stick moving it up (forward) or down (reverse)

So why don't you help me out... none of the websites I find break it down so a non RC heli person can understand it.. Do I need to take a class or something? How's a guy supposed to get into this hobby if there is no simple help?

In heli parlance, "pitch" refers to the angle of attack of the rotor blade ... not the orientation of the nose (ie nose up / down or elevator).
"pitch" is measure at the cord of the blade. When the cord line is parallel to the ground (assuming the heli is sitting level), this is 0° pitch. If the leading edge of the blade is angled upward from level by say 5° this is called +5°.

Go back a read this:

Does the walkera 60 have fixed pitch or collective pitch?
What is your pitch settings (angles of attack at each stick setting ... lo, mid, hi)? You will only have one setting if FP.

Pitch is measured with a pitch gauge attached to the rotor blades to determine the angle of attack (pitch).

Status: offline 		Tippy thanks for that awesome explaination. How much do pitch gauges run? I'm guessing that is what I will have to purchase. The 60 is CP so I guess I have to adjust it to get it off the ground.

This is the one I use. You can find it at www.heliproz.com

Status: offline 		a good setting for the df60 is -1 at low +5 at mid and +11 at high in normal flight mode (the right toggle switch flipped to the "N" possition) also make sure your blades are ballanced (make sure the are the same weight) and be sure to adjust the tracking as well (when the blades are going really fast make sure you can only see one set not two, this is why they have differnt collors on each blade... so you cand see whitch one is lower and ajust the pitch of it to match the other blade)

I hope this helps you with your df60 and oh by the way setting the pitch is a little hard on this model unless you mess with the "PIT" and "exponintial" functions on your tranmitter.... see manuel for the ,how to. by the way "PIT" ajusts how far your servos can move and the "exponitial" ajusts how they respond to your controller.
anyway I hope this helps. it took me a while to figure that out.

Status: offline 		Thanks for that info joshnakken, I'll put my heli on the table tonight and try to figure out which screws I need to loosen to adjust the pitch of the blades. How do I adjust it for the different levels i.e. low, mid, and high?

Thanks for all your help.

And thanks for the help with the pitch guages guys

Before the days of laser tracking guages etc, a piece of coloured to chalk would be put on the end of each blade, then someone had the lucky job of holding a stick with a stretched piece of cloth on and moving it carefully to the edge of the rotor disk until each blade left a mark across it. Look at the cloth and see which blade was high/lower than the rest. I would use the tip of a felt pen and a piece of paper, they dont have to be exactly level, but anything more than 2-3mm should be adjusted.
