Hi,Im new on here and like to say hello.
I have had a Horrobo Shuttle ZTS for nine months now and im finding it very interesting.Ive progressed to forward flight and have attempted some rolls and a few loop the loops.Crashes have appeared now and again,but i have learned by my mistakes.

Thats enough about me now here's the question.

I have read on these forums that some people have a pitch curve of -!0, 0 ,+10(0 being center stick) would that be on there normal mode or idle up one.I do know that if your are attempting 3d you set up your TX on idle up two to this.
Because if its on there normal, surely if there throttle curve is 11,25,50.75,100 at lift off there throttle would be around 75%.
I read on here that some people,mainly 3d,have there stick at three quarters for hover.To me that would be 75% throttle.
There may be an obvious answer but not to me.
Thanks

hi

i have it set up +- 10 or what ever your engine will take across all flight modes then i dont usually touch the pitch curves anymore,if i do it just the low and high points then just adjust the points on your throttle curve to get the head speed you want.

To me that would be 75% throttle
Yes, that would be correct. 50% throttle opening at 0º pitch , half stick. I also have then same set-up as Andy. 10/10 or whatever in all flight modes, including Throttle Hold. You can trim some of the negative off the Normal, for an easier landing, but once you get used to the 10/10 it's an easy transition.

personal preference
I prefer to hover at 50 - 55% stick input, just in case I decide to take the heli up to a higher altitude I have enough input to slow a quick decent.

I may be totally wrong, I have not even programmed the second mode for forward flight.

Actually with the pitch curve at -10 / 0/ +10

your throttle curve should be:
100% 50% 35% 50% 100%

The hovering point would be about +5 deg @ 50% throttle.

The Normal curve would be -5 / 0 / +10 so you have a mellower bottom curve to help in smooth landings.

The throttle curve would be:
0% / 25% / 35% / 50% / 100%


Of course the % values are variable depending on the heli equipment and setup.

Yes, where you hover, has nothing to do with what it takes to stop a fast decent.

I like to run linear curves on all my modes.. normal, idle-up1 & 2. this prevents any variations as i go throug my stick inputs and everything is even. my V curve in idle-up1 was 100 70 55 70 100. this maintained my headspeed at about 1800 - 1850. I have a throttle jockey now so i let that worry about the headspeed so i dont use my curves anymore.

im running a OS 61 on a R60, 30% CP

that v curve pic showing 35% on point 3 is too low. you can loose alot of headspeed if you bring down your stick to center and bang your elevator or aileron.
