my only concern
6. Swash - A +50%, E+50%, P-34%
ideally get the swash of P to 50 and set the linkages mechanically... with 34% you will be compromising the pitch travel a lot
7. Pitch angles - Normal -2, +5, +10
my personal recommendation is -2, 0, +10

Anwar, you mean I should take the Pitch up to -50? Then the pitxch angle at max will probably go beyond 14. You would advice me to bring this down by adjusting the blade grip linkages?

hi mate.
do you get 'actual' +10 pitch at full throttle?
if so then no need to alter the swash setting.
have you tried to fly or hover the craft yet?
with that small pitch number the swash will not move much, and you may find you have very fast pitch change,

normal setting for swash is 60% for all three and some times you need more on pitch..it all depends on the setup and servos throw you are using.

I guess the question is for RcBazaar

Thanks Sunk and Anwar. I have started afresh to see if I can correct things any further. Yes I was getting an actual +10 on full throttle and -2 at zero throttle. No I have not taken the MT for a hover as yet. Thought I would get my funda in order first and get my setup to a point where the Gurus will say "Ok I think you can now give it a go".
By the way Anwar even when my pitch curve is 25-50-65-80-100 my pitch angle at mid stick should read 0? Because during setup with a linear pitch curve of 25-50-100 I think i had had 0 at mid stick.

I am not sure if the questions are directed to me or at RcBazaar/sujju.  Anyways, there are 3 different ways people setup pitch curves for normal flying/hovering.

1) "-x 0 +x" at zero, mid and full throttle stick positions.  Here "x" is 9 to 13, depending on the heli, and your style of flying.

2) "-3 +5 +x" at zero, mid and full.  The idea here is to hover at around middle stick.  This has the disadvantage that going to idle-up (3D modes) will cause the heli to sink, because the mid stick pitch will change from +5 to 0. But this may be better for absolute beginners because there is a wider pitch range around mid stick for finer adjustments.

3) "-3 0 +x".  This one is similar to [2] above, but avoids the pitch jump when you go to idleup/3D modes.  In this setup, your hover point will be above mid stick, somewhere around 65% to 75% position of the throttle stick.

So these are the choices when you are at 0, 50 and 100 on your pitch curve.

Note that this "-3" etc are not hard numbers, some people to -2 instead, others go to -4.  These are sort of guidelines.

Thanks Anwar. No.2 is what I had in mind as I am a total beginner with helis and all I have flown are 4 ch fixed pitch and some simulator. In that case my readings of -2, +5 and +10 should be ok giving me hovering at around mid-stick.
Thanks Sunk and Anwar for all your help. Will wait and see if Sujju has any suggestions.

Hi sunk and Anwar ( and anyone else out there)
I did some more homework, checked out Finless and other posts  and came to the conclusion that there are different schools of thought determining what the pitch angle should be at mid stick for a beginner. Some swear by +5 and others profess 0. Both have their "good and bad". The low end and the high end are non controversial at -2 or3 and +10 or 11. Anyway, as I had stated in my last post, I re did the full set up for the Mini titan again and got -10, 0 and +10 on linear pitch curve of 0, 25, 50, 75 and 100 with throttle at 0,25,50,75,100.   
So now I have set it up as follows:
Th Curve     - 0, 45,65,85,100
Pitch Curve - 45,55,75,85,100
Pitch angles - -2, 0, +5, +8, +10
I think that should be as good a beginning as any. However if I find that the chopper is unsteady at mid stick hover, I'll up the throttle from 65 to 70.
Cheers.

I will let you in on a secret  

For a beginner, absolute precision about these setups/numbers are just academic exercises !  If you are in the general range of values, what matters are your thumbs (i.e. sim time you have put in).  What goes wrong with many people is that they slam the heli down during landings, based on their sim training (and sims are very very forgiving).  Landing are to be done very gently, like trying to hover in one height, and then lowering the throttle stick just ONE click... and let the heli slowly come down on its own.  In other words, don't "fly it down", unless it is an emergency situation.  It has to "float down" instead.

Pradeep,

You should keep the Throttle curve as linear as possible and if you feel that the head speed is too much to handle (heli is very twitchy) then bring down the TH curve settings (still try to keep a straight line) .Your pitch at mid stick should always be 0 degrees as it will prepare you for 3D flying, and you can keep the -2 pitch at low stick for normal mode which is just to bring the heli down if you are flying it in a little windy day.

Hellyflyer

Now that gives me some reassurance! Thanks Guys.

hi mate.
the -10....0......+10 is to ensure you have full pitch range when setting up, and is used in idle up/stunt mode.

in normal mode -3..... +5 .....+10 is more normal and used for learning as the 'hover' is then around mid-stick+,    which is more comfortable for most.

so both options are right.

once setup you can alter the pitch at various stick positions with your pitch curve in the computer type tx to suit your level of flying.
