Needs Help
 

Dear all,
I am a new RC helicopter player, I bought JR Voyager E and JR PCM9XII; JR 490T Gyro with Servo.
I use 8.4V Ni-Mh 3.6A battery. Everything is use the JR original Kits which included in Voyager E.
I have not do any upgrade for this helicopter due to I am a beginner (I never paly Helicopter in before)
I follow the Voyager E instruction manual to set up my toys.
I did balance the Blade in yesterday and I tried to play it today. However, I found out the helicopter is virabtion very serious.
Besides, I push the Throttle up to to 2/3 position the helicopter seems will take off but cannot and the tail turning from right to left (if I look from the tail of the helicopter.
I hope someone can teach me what reason I did wrong ? Pitch problem or else ?
To tell the true, I am not very understand how to set up the PCM9XII Radio.
The place which I living (my district)is no one paly helicopter and there is no one to play RC Helicopter in my friends so I need to do bymyself.
If you have any suggestion for me this beginner, could you please teach me ?
Appreciate all helicopter's players !
