Newly built Ionx-2. During first few flights, the head seems very "mushy". Set up to exact manual settings.

Any ideas?

get the harder durometer (90 i think) head dampers from ronlund/heliproz south. also make sure you have the metal headblock installed.

i got a stratus and had the same when i bought it, then changed them and it was nice and stiff.

!boo!

Is there a specific spec or stiffness in dampners I should call on?

Is NOT the dampers
The "mushy" feeling is all in the collective. Cylic feels ok.

I cranked the collective up and even in +12 -12 feels mushy.

It could be the rpm which I forgot to tach,

Still, flyingbrian's Freya at 1500 feels absolutely precise. His Ion X collective wanders around in comparison.

He was was using s9252 which are very accurate servos.

If it feels unstable. Then set up the heli by using a clear square. Then sub trim the servos 90' to the main shaft, set up everything 90' to the main shaft you can't eye ball it. They will feel unstable if it is not square at zero pitch.

The trim will move the servo ball .0015 of a inch. It is very precision.

My first fury someone (a very good flyer ) eyeballed it and it had a unstable feel. After I went through it and made everything right. It felt locked in.

All subtrims were zero, everything was dead squared.
Swash collective mixing was maxed out until it almost bind with cyclic.

A bit unstable in the begining at lowest flybar ratio, but after adjusting that, cyclic felt good in wind or calm.

The weird feel is only on collective.

punch up ok, as it comes down quickly you add collective,
and add collective
and ADD MORE COLLECTIVE

and finaly reacts and stops the fall. Blades were Mavrikk wide chord 690s

even a sloth700 at 1000rpm stops a decent faster
.

Power is the original Actro 32-4 with Jazz ESC. Not sure of the gear ratio

how old are the cyclic servos?

9252's are a brilliant servo. I'm using 9255's which are a little better, but still after a VERY long nose dive, it does take a little persuading and bending on the coll stick to arrest the fall and get her level again, lol, my stratus is a little on the heavy side at 5.5kg, She fat like her owner.

Maybe your servos are being driven at a lower voltage, they can take 6v forever. Its been proven

A pic of your heli would be good too.

thr 9252 are only 5-7 flights old.

Powered by a Western Robotics hercules, 2 leads to the RX at 5.2V

To be more specific, the deadness is around zero, at full collective is reacts normal. Between zero and 6 is like there are no blades.

like I said, I cant make heads or tails of this.

Old yeller after being shot had more life than the collective on this Ion.

FlyingBrian,

We need to tach this thing to know for sure what is the RPM

Hi chago! Make sure there is no expo dialed into the pitch curve. On another note are you going to marks meet next week?

double checking TX set ups, and the heli was not programmed with Pitch expo.

No expo, straight line pitch.

The head RPM may be too low (gearing) and it behaves mushy.

Planning to go with Milner Sat or Sunday to Mark.

If we are correct, the gear ratio is about 10.97:1
Main gear-93T, pinion 12t, motor pulley 24t, large pulley 34t

Does anyone knows for sure what is the KV on the Actro 30-4?

My colleage says 555kv, but sone places online say is 415kv
Which is right

The 32-4 is 415 the 32-3 is 555. I did not see any 24t motor gear listed, saw a 22. If it is a 22 the ratio is 11.97 from MA chart.

10 cell batt the head speed will be 1,282

12 cell batt the head speed will be 1,525

44volt * 415 = 18,260 \ 11.97 = 1,525 head speed

Using 10S
You are correct, I did not see a 24t pulley either. if is the 32-3 motor at 555kv then:

Throttle 75% 1561rpm
Throttle 80% 1605rpm
Throttle 85% 1649rpm

If is the Actro 32-4:

Throttle 75% 1167rpm
Throttle 80% 1200rpm
Throttle 85% 1263rpm

Either way, it sound like we found the issue, too low rpm.

24T motor pinion is available, as I have 2 of them, one with a 6mm bore and the other with an 8mm bore.

My set up:

Ion X2
Neu 1912 1Y 825KV
TP 4400 12S 65C
HW 120HV
V-Bar full size blue line W/Gov active
8717's on cyclics and a BLS251 for the tail
CC Pro V2 BEC set at 5.6V and run from only one of the main batteries
22T motor pinion and 44T driven pulley for a 15.5:1 GR
Head speed set at 2100 at 11% headroom below nominal battery voltage.
Motor RPM approx. 32,600
Collective pitch is set at 14+ degrees
Cyclics are set as much as possible w/o binding

I first started with 1900 HS and 12 degrees pitch and it was very mushy on the collective. Then turned up the pitch to 13 degrees, better but still mushy. Turned up to 14+, now it performs well, and that little Neu motor has a lot of power. It pulls through the high pitch and cyclic range very well. Now, when I fly hard, I've found the weak point is the crown gear...I've done some things to make it better, and it is better, but still the weak point on the whole heli.
