Not twitchy at all. The best way of describing the pedals is as follows. For those that drive manual cars think of it like this. The clutch on your car will need adjusting just before a service so the pedal travels a long way before the effect, thats your notar. After service clutch is adjusted so the clutch pedal now like an on off switch thats your tail rotor.
Basically it doesnt react as quick but it will then over react as you put too much input in. Once you are used to it it is easier to do spot turns. Best fun with a new pilot is to put one in the hover and take your feet off the pedals, she will sit in the hover and if you are gentle you can transition a way fly a circuit and back to the hover without using the pedals !!!! A very surprised new pilot:
