What kind head speed have you got ?

Also with a stock motor you might need a little more pitch than called for

Dont try using a 10cell (12v) pack with your stock motor or speed controller you'll toast the lot!! They are not rated for that power!!

The 10cell I recommended is for using with the brushless Hacker C40 and appropriate controller.

You could try 9.6v but we aware that the stock speed controller is I believe only offically rated at 8.4v, though a number of people have used it with 9.6v, so its a bit of a gamble. The stock motor will run at 9.6v but you will probably find yourself having to replace the brushes on a regular basis.

The only real answer is the brushless route. Unfortunately the cost of doing so, as I found out, was more than the cost of my VoyagerE in the first place!!

But it was worth it and I wouldn't part with mine now!!

Maybe I'm mistaken but I guess the problem lies in
with set up as book on tx .
throttel and pitch curves as in book ..
I'm not sure what you mean by "as book on tx", but
I guess that the actual throttel and pitch curves
are quite different from those given on manuals
that come with the TX. For example, the manual for
my tx gives example pitch and throttle curves like

Normal Pitch curve: 24% 30% 55% 75% 95%
NOrmal Throttle curve: 0% 30% 50% 70% 100%

I remember reading somewhere that these "example" curves
are based on nittro helis, and the curves for EP helis
should be different. Probably you can "Search" this
forum to find what other people's pitch and throttle
curves are like.
