Tail little moves right when i suddendly increase collective

[maRRRco]

no, i am in avcs
i'm not no newbie
ehehe
and however with 65% in the gyro menu, the behavior is the same

maybe a 13T pignon is little for hard collective manouvers, i just ordered a 14T

i will fix, i'm waiting my order

my gyro set up
align gel with align band, gp750 with ds520
limit perfect, slider moves side to side to endopints
setting for small helis, red light
no delay
set up with servo arm 90° and hover in rate mode with no trim o subtrim, only adjusting pushrod
flip the grips

gain with ATV set to 40% and same issue in full collective

i think tail must not move also with +11 collective and fast imput

but i don't know how again i do

My tail shaft had some play in it too...I used a thin metal washer to fix that.

I still wonder if you have enough headspeed. The TT does actually have a little bit of a lower tail ratio than the belt tails. This is to allow for more headspeed. So a 13T may not be getting enough tailspeed? Does your motor bog when doing collective? 25C batts aren't enough.

in your opinion, if the mechanic is perfect in all aspect as i'm trying to do replacing all incognite parts
this issue can be caused only by headspeed, or it is an elettronic issue??

i don't know my RPM, i don't have a tachometer, but 25C are not enough??
maybe the 13T is not enough
the motor doesn't bog in full collective

are you sure that a flat curve is better then a V one??
if there is a headspeed problem, where tail lose authority, a V curve can keep the Rpm costant when i increase collective
for example
with 100% flat curve 3200 rpm at center stick
when i increase they become 3000

if i set 2800 rpm (90% curve) to center
and i increase collective they should become 3000, for pitch and torque they stay at 2800

it is only an example, maybe don't concern my problem

If the headspeed drops when you apply collective then that might mean that the tail is losing authority. If the tail loses authority it will move over to the right.

The other scenario is if you use a throttle curve that creates a lot of torque when you apply collective the tail will also want to move over to the right. The steeper the throttle curve the more this effect.

Another thing to consider is that with a low headspeed more of the rotation gets made into torque instead of lift. As you use a higher headspeed the blades get better at making lift and make less torque.

So the best thing for the tail is to have a higher headspeed and to have the headspeed stay nice and steady. This is why many people like to use a 14T with a flat 100% throttle curve. The other option is to use governor mode(it is complicated to set up and the stock brand isn't the greatest).

Try the 14T and definately try to get a higher C rated battery(it will fly better).

+1.....

100% throttle curve in idle up is working the best for me now after 5 months fooling around with it.....

well well
now i have a new enthusiasm
i'm so excited to try

I Must win, not heli, your help is fondamental for me
thanks

You will get it right.... Never give up.....

I've noticed on pictures of this problemed mismarvel that the tail blades have more pitch with the slider to the left than when the slider moves to the right. That won't fly, at least not correctly. Has Align addressed the issue? If not I'm not buying one! I don't settle for mediocrity and you shouldn't either!!! Time to boycott??? They haven't adjusted their prices in our economic crunch anyway!
