during my first hoverig session, nevertheless i was using exponential setting on cyclic servo command i incurred in overcontrol with near catastropich tail boom strike damage by blade contact.

my mistake was(now i now!) setting almost 100 (mechanical end to end) travel
on radio.

wich are the forum experiences in the correct travel have a good command autority without incurring in tail boom strike (enev at high g manoeuvres)?

If you have it, try using dual rate instead of exp. I have dual rate set to 55% on my Futaba 7CH (FF7) and the cyclic is a puppy.

Damn nose in hover

I , myself, use a lot of expo and no dual rates. Trhen I don't have to flip any switches and if I need 100% throw I can get it, I just go to 100% stick. I set my ATVs even on each side of the throw to where there is no binding on the servo. That is Aileron is 90% LEFT and 90% RIGHT.

On the T-REX I use a ton of expo, 75%, this allows for near FAI stability in the hover. However I can go to full stick and get some good acro moves in.

Dose'nt matter where your setup is if you set this bird down on the hard side it will boom strike. If you are a newbie, which I think you are you have to go into your pitch settings and take away most of your negative pitch, so you dont slam it down when you get into trouble, zero to negative one degree at bottom stick would be a good starting point for you, but dont fly it a strong breeze because it will tend to float around a bit. Hope this helps.

Set it up so you have 6deg of cyclic pitch. You don't need much swash plate travel to get that.
I originally set my endpoints up to have max cyclic movement without anything binding. While tracking the blades once I was moving the cyclic around a bit and I swear I could have caused a boom strike if I gave it full up 'elevator'. I set the dual rates down to about 65% and on my setup that gives me 6deg of cyclic pitch, which for is enough to do stationary flips and rolls.

I never would have thought the heli could be so agile with such a small amount of swash tilting, but I'm a noob so that's why I thought more is better.

Think I read somewhere that anything over 6deg of cyclic pitch isn't good as it will cause the blades to stall. Hopefully some experts can chime in on this.
