Just Got My New T-rex Brushless It Really Scared Me To Death !!!

I just receive my first T-RE HDE already assembled from GWS-EXPERT.
I already have since 3 months a HONEY BEE CP2 and before i have flown for 4 months on G3 SIMULATOR with good flying results and beginning to do some 3d figures that i have never had the courage to try on my CP2 for the moment...
My new T-REX is all ALIGN BRUSHLESS set up with A HITEC OPTIC 6.
This early morning i try it for the first time......and belive me compare to my CP2 he scared me to death I just try some hovering and discover that this beast is very very sensitive compare to my CP2 and this put me a little of sadness because maybe i bought an heli that is not a good choice for a beginner like me ... anyway i have done only some hovers and move a little bit in fron and rear but i was too scared to try a real fligh cause a crash.I have noticed also that the rear rotor move a little from right to left and viceversa like a little zig zag.....is it normal or is there something wrong ?
I'm sad and scared...PLEASE any help and advises...

Same happened to me going from a Blade CP to Trex - believe me, after you get used to it - you'll think the CP2 is slow and lazy.......

Sorry to hear of your disapointment.

Dial in a bit of Dual Rates on the Optic 6, should help calm down the Rex.

About the tail, is it just moving from left to right yeah? It may be that your GAIN on the gyro is too high. Try reducing that, and see how it is. Oh, what gyro is it?

Going thru that scary part myself, but loving every bit of it!! Can't wait until I have the to take it on a full flight. Right now just hovering around, coming from a GWS MiniDF this TREX is a total beast. Enjoy!!!!!!!!!

Dial in some expo, about -25% to tame it down a bit while your thumbs are getting used to it. Once your brain can deal with the responsiveness and higher headspeed you will start dialing it out again. I started out with 40% on my X-400 and quickly got rid of it and now I love the responsiveness.

Try adding some flybar weights as detailed here
http://trextuning.com/flybarweights.htm

I had some paddles off a dragonfly #39 on mine to start with, which was like having thd dual weights, and an experienced pilot tried it out and said it was a good "trainer" since the cyclic response was nice and gentle.

I've no gone to lighter weights, and now to removing them altogether as my skills progress and it sure is snappy compared to running the weights.

Yep, that's my story too! Like the others have said, some expo or dual rates programmed in will help and you will get used to the responsiveness. I'm glad I had the Blade as a stepping stone.

You have the right Heli. Just take it easy until you feel comfortable. Hover and practice. It is great little Heli just totally different from any Sim I have tried and also the CP2. As far as the wagging you mentioned fly it a bit more and reduce the gain on the gyro very slightly.

There's a section "Reducing helicopter twitchiness" in the EHBG which should help you.
