First off I would change you pitch curves to the same for all modes.
-10/0/10
There is nothing necessarily wrong with what you have now but in the future when you step up to aerobatics you don't want a sudden pitch change when changing flight modes. Better to set it now and get used to it instead of having to change it later.

As to your question:
You've already learned about transitional lift but there is another significant factor involved in the maneuvers you are flying. When doing slow figure 8's you are using mostly the tail to turn the helicopter. When you do this you are changing the load on head causing the head to speed up or slow down depending on the direction you are turning. A turn to the right uses more energy than a turn to the left due to the torque induced by the rotor. So a turn to the right will reduce you head speed (ever so slightly) thus producing less lift. The opposite is true for a left turn.

I went through the same learning steps you are doing now and I just learned to increase or decrease the collective to maintain altitude. A governor helps some but you still need to constantly adjust the collective to maintain your altitude.

And the more you fly the more you automatically learn to not use pitch as much in FF

Same as with an airplane, the faster you go the less elevator is required to maintain the same altitude.

Setup is everything, All my heli's can fly far better than I can pilot them

cool all great advice but I do have a question:

-10/0/10

.......I'm supposed to have -10 to + 10 in normal mode? if my normal pitch curve is -2/-1/0/5/10 and my idle up is -10/-5/0/5/10 this wont give me any pitch change when switching correct?

Good information already posted, just wanted to say I have the same thing. The faster you go, the more lift you get. A plus is you also get more time from your pack! I can clearly see a difference in how much charge it takes after hovering, vs. flying 8's or just zipping around the field (no 3D). This is in normal mode, I have yet to progress to idle up.

I didn't go to -10/0/-10 in all modes until I advanced to 3D. It is a matter of personal preference. With -2/-1/0/5/10, you shouldn't have a collective pitch change when switching modes, but the collective will be just as sensitive, unless you lowered your throttle curves a tad in Normal mode. I'm not crazy about the idea of novices learning on -10/0/+10. That just leads to discouragement. Mechanically setup the heli for 3D (if that's your goal) and set up your curves on your radio for training. The argument about "Learn 3D curves right off the bat" is ridiculous IMHO. You should "transition" away from training modes as your skills improve.

FWIW, I encourage putting the pitch curve in Normal for novices at -3 to +10, straight line, with no kinks. This softens the collective and makes it less jumpy. Even for beginning hovering on the training gear, I'll even encourage 0 to +8 or something like that on small electrics. That way, if you're hovering a couple of feet off the ground on training gear (no higher), and you start to lose it, bringing the throttle/collective stick full down won't hurt it at all, whereas if -3 degrees were suddenly applied in a panic, you'll break something.

Yes, that will give a collective pitch change when switching modes, but it won't make a difference if you:
1) Change modes up high or,
2) Change modes on the ground at mid stick.

Once your confident and safe enough, then switch everything to -10/0/+10.

Just wanted to say thanks for all the advice.My slow FF is comming along well now,My fig 8's sort of look like an 8 nowand I can keep a constant altitude MUCH better now. as with everything else practice is the key and I'm taking my time and not getting any bad habits(I hope)as I'm learning my hovering in ALL directions moving clockwise and counter so I dont start to favor any one direction....also today I did my first nose in take off's and landings and it went well(heli's in one piece)although I did need a cigarettebut Thanks for all the tips and advice ....What would be my next step after I get the fig 8's a little neater and I'm ready to move on??

Your next step is quiting smoking! I'm gonna rip you for posting that on here! You are paying to "kill yourself" any educated person today knows that smoking is a retarded thing to do!
Back to helis, nose in like it is your job. I learned next to fly backwards. Altitude is your friend...

My Grandmother was well educated and kicked the HABIT,,finally.
She quit at the age of 91,,cause her home said no smoking,,, she died of other causes within a year of quiting. I did quit it was the best thing I have ever done for myself though.

By the way though don't buy any food from other countries like China,,South America,,etc,,DDT is rampant along with other pesticides known to cause cancer. America asks,,is it chemical safe?? They say YES!!
No one there or here check it all,,,,, but it won't kill you for 20 years
Dont smoke ,,dont eat,,dont buy retarded stuff,,,,good luck,,,

Hi

When i think back to 'when i learned'....

I had flown planes for about 14 years. I found the collective very sensitive in hover.

In forward flight, even slow FF, i was suprised how much i needed to move the collective stick to keep it at a constsnt altitude and speed. Turning from into wind to down wind was one problem area. The second was learning to stop....i felt i was comming off the stick way too much, but it was necessary.

Setting your pitch curve and throttle curve becomes more imprtant when you start flying about. When hovering, you are realy only at one stick possition.....quite easy to set. When flying, you move the stick alot more and this makes the setup necessary over the whole range.

Regards

Paul

...this is what surprised me a first which is why I thought I was doing things wrong.....but since its rarely perfectly still the wind is a big factor also.....its funny the more I learn the more I see how much there is to learn
