My new t-rex 450 se v2 flies good,but I have a problem. The heli turns to the right as soon as I hit the throttle hold switch. Is this normal? Any help will be greatly appreciated thank you all.

what radio are you using? some radios have different trim setting in thr hold and IDLE 1 and 2.

I am using a dx6 withe hs-65mgs on the cyclic and a 401 and a 9650 tail servo.

What is your throttle hold pitch curve like? The other thing to remember is that 450 size helis really don't auto well, the blades are too small to maintain much momentum.

im not too familiar with that radio but look at the trims then flick the switch and seee if the trim moves if it has digi trims. not much else i can think of. is the gyro in HH?

Sounds like you have revo, tail offset set up in the hold. A little is the norm as the 450 tail does not hold that well when banging the throttle. Your gyro gain could also be too low.

It doesnt really matter which mode it is in,but as soon as you hit the throttle hold it swings hard to the right.

has it always done this or have you had it flying without the tail kicking out? does the gyro stay in the same mode when you fick the throttle switch?. The tail will always kick out from the torque effect when you kill the throttle, but the gyro should be able to stop most of it. Check all the tail linkages are smooth and check that autorotaion gear is spinning freely so theres no unneccesary drag from anything when you flick the switch
