no lift

What is "pitch up" I have finally got my piccolo to hover pretty good and have been practing nose in flight, but can't seem to get it to do anything but hover. When I move it foward everything goes fine untill I let off and then the tail dops back and loses all lift. It pretty much does that in any which direction I fly? is this normal physics and do I just have to learn how to compensate this by SLOWLY let off of foward (or any direction) flight.??

As you translate from hover into forward flight, the forward-moving blade will generate more lift than the backward-moving blade. Intuition suggests this will make the heli want to roll, but gyroscopic precession means that instead of rolling, the heli pitches up i.e. tail down, nose up. As you come out of forward or backward flight you need to add some throttle to remain hovering as the heli loses its translational lift.

Certain blades are supposed to help combat pitch up by being stiffer etc, but my guess is that they simply rotate faster to create the same lift so the progression from hovering lift to translatory lift is a bit smoother. You could try depitching your blades a little to get more revs, which should make the translation a little more manageable. Unfortunately my flying hasn't allowed me to test this in practice, but someone with more experience will be able to comment further.

The pitch-up is also because of the coning which happens with the standard blades and it's truly the worst thing about the Piccolo, in my opinion. Adding a head stiffener will help to counteract it. Personally though, I found that even that didn't stop it enough (although it's much better). The CP Piccolo does not suffer from pitch-up problems, at least in my brief experience of it, and it's far, far more pleasant to fly as a result.

yes you can beat pitch up,rotor head mods,lower blade pitch and more forward c of g and you can rip the fixed pitch pic around the garden no problem.

It's not clear to me that coning contributes to pitch up. Wouldn't you think that pitching torques from coning would actually result in a rolling moment through the gyroscopic coupling? The principal cause of pitch up is differential lift between the advancing and retreating blade. This effect is mitigated with CP because of the higher head speed. Also, I think that the primary benefit of head stiffeners is to give more precise handling during sharp changes of direction. They do also reduce coning but it's not really clear how this helps things.

In any case, I had a severe pitch up problem with the stock blades on my FP, but this largely went away when I switched to MS blades.
